'Fishing for what, for hell's sakes? If there's a story, share it. Who gave you Frost for free? Where can you go that is not more beautiful for Brother Lukie's presence?'

Pretty well anywhere, Jerry had said unkindly, and managed to leave without waking him.

He made first for the market and sipped a soupe chinoise, studying the stalls and shop fronts. He selected a young Indian who was offering nothing but plastic buckets, water bottles and brooms, yet looking very prosperous on the profits.

'What else do you sell, sport?'

'Sir, I sell all things to all gentlemen.'

They foxed around. No, said Jerry, it was nothing to smoke that he wanted, and nothing to swallow, nothing to sniff and nothing for the wrists either. And no, thank you, with all respect to the many beautiful sisters, cousins and young men of his circle, Jerry's other needs were also taken care of.

'Then, oh gladness, sir, you are a most happy man.'

'I was really looking for something for a friend,' said Jerry.

The Indian boy looked sharply up and down the street and he wasn't foxing any more.

'A friendly friend, sir?'

'Not very.'

They shared a cyclo. The Indian had an uncle who sold Buddhas in the silver market, and the uncle had a back room, with locks and bolts on the door. For thirty American dollars Jerry bought a neat brown Walther automatic with twenty rounds of ammunition. The Sarratt bearleaders, he reckoned as he climbed back into the cyclo, would have fallen into a deep swoon. First, for what they called improper dressing, a crime of crimes. Second because they preached the hardy nonsense that small guns gave more trouble than use. But they'd have had a bigger fit still if he'd carted his Hong Kong Webley through customs to Bangkok and thence to Phnom Penh, so in Jerry's view they could count themselves lucky, because he wasn't walking into this one naked whatever their doctrine of the week. At the airport there was no plane to Battambang, but there was never a plane to anywhere. There were the all-silver rice jets howling on and off the landing strip, and there were new revetements being built after a fresh fall of rockets in the night. Jerry watched the earth arriving in lorryloads, and the coolies filling ammunition boxes frantically. In another life, he decided, I'll go into the sand business and flog it to besieged cities.

In the waiting room, Jerry found a group of stewardesses drinking coffee and laughing, and in his breezy way he joined them. A tall girl who spoke English made a doubtful face and disappeared with his passport and five dollars.

'C'est impossible,' they all assured him, while they waited for her. 'C'est tout occupe.'

The girl returned smiling. 'The pilot is very susceptible,' she said. 'If he don't like you, he don't take you. But I show him your photograph and he has agreed to surcharger. He is allowed to take only thirty-one personnes but he take you, he don't care, he do it for friendship if you give him one thousand five hundred riels.'

The plane was two-thirds empty, and the bullet holes in the wings wept dew like undressed wounds.

At that time, Battambang was the safest town left in Lon Nol's dwindling archipelago, and Phnom Penh's last farm. For an hour, they lumbered over supposedly Khmer Rouge-infested territory without a soul in sight. As they circled, someone shot lazily from the paddies and the pilot pulled a couple of token turns to avoid being hit, but Jerry was more concerned to mark the ground layout before they touched down: the parkbays; which runways were civil and which were military; the wired-off enclave which contained the freight huts. They landed in an air of pastoral affluence. Flowers grew round the gun emplacements, fat brown chickens scurried in the shell holes, water and electricity abounded, though a telegram to Phnom Penh already took a week.

Jerry trod very carefully now. His instinct for cover was stronger than ever. The Honourable Gerald Westerby, the distinguished hack, reports on the siege economy. When you're my size, sport, you have to have a hell of a good reason for whatever you're doing. So he put out smoke, as the jargon goes. At the enquiry desk, watched by several quiet men, he asked for the names of the best hotels in town and wrote down a couple while he continued to study the groupings of planes and buildings. Meandering from one office to another he asked what facilities existed to airfreight news copy to Phnom Penh and no one had the least idea. Continuing his discreet reconnaissance he waved his cablecard around and enquired how to get to the governor's palace, implying that he might have business with the great man personally. By now he was the most distinguished reporter who had ever been to Battambang. Meanwhile, he noted the doors marked 'crew' and the doors marked 'private', and the position of the men's rooms, so that later, when he was clear, he could make himself a sketch plan of the entire concourse, with emphasis on the exits to the wired-off part of the airfield. Finally he asked who was in town just now among the pilots. He was friendly with several, he said, so his simplest plan - should it become necessary - was probably to ask one of them to take his copy in his flightbag. A stewardess gave names from a list and while she did this Jerry gently turned the list round and read off the rest. The Indocharter flight was listed but no pilot was mentioned.

'Captain Andreas still flying for Indocharter?' he enquired.

'Le Capitaine qui, monsieur?'

'Andreas. We used to call him Andre. Little fellow, always wore dark glasses. Did the Kampong Cham run.'

She shook her head. Only Captain Marshall and Captain Ricardo, she said, flew for Indocharter, but le Capitaine Ric had immolated himself in an accident. Jerry affected no interest, but established in passing that Captain Marshall's Carvair was due to take off in the afternoon, as forecast in last night's signal, but there was no freight space available, everything was taken, Indocharter was always fully contracted.

'Know where I can reach him?'

'Captain Marshall never flies in the mornings, monsieur.'

He took a cab into town. The best hotel was a flea-bitten dugout in the main street. The street itself was narrow, stinking and deafening, an Asian boomtown in the making, pounded by the din of Hondas and crammed with the frustrated Mercedes of the quick rich. Keeping his cover going, he took a room and paid for it in advance, to include 'special service' which meant nothing more exotic than clean sheets as opposed to those which still bore the marks of other bodies. He told his driver to return in an hour. By force of habit he secured an inflated receipt. He showered, changed and listened courteously while the houseboy showed him where to climb in after curfew, then he went out to find breakfast because it was still only nine in the morning.

He carried his typewriter and shoulder bag with him. He saw no other roundeyes. He saw basket-makers, skin-sellers and fruit-sellers, and once again the inevitable bottles of stolen petrol laid along the pavement waiting for an attack to touch them off. In a mirror hung in a tree, he watched a dentist extract teeth from a patient tied in a high chair, and the red-tipped tooth being solemnly added to the thread which displayed the day's catch. All of these things Jerry ostentatiously recorded in his notebook, as became a zealous reporter of the social scene. And from a pavement cafe, as he consumed cold beer and fresh fish, he watched the dingy half-glazed offices marked 'Indocharter' across the road, and waited for someone to come and unlock the door. No one did. Captain Marshall never flies in the mornings, monsieur. At a chemist's shop which specialised in children's bicycles he bought a roll of sticking plaster and back in his room taped the Walther to his ribs rather than have it waving around in his waistband. Thus equipped, the intrepid journalist set forth to live some more cover - which sometimes, in the psychology of a fieldman, is no more than a gratuitous act of self-legitimisation as the heat begins to gather.

The governor lived on the edge of town, behind a verandah and French colonial portals, and a secretariat seventy strong. The vast concrete hall led to a waiting room never finished, and to much smaller offices behind, and in one of these, after a fifty-minute wait, Jerry was admitted to the diminutive presence of a tiny, very senior black-suited Cambodian sent by Phnom Penh to handle noisome correspondents. Word said he was the son of a general and managed the Battambang end of the family opium business. His desk was much too big for him. Several attendants lounged about and they all looked very severe. One wore uniform with a lot of medal ribbons. Jerry asked for deep background and made a list of several charming dreams: that the Communist enemy was all but beaten; that there was serious discussion about reopening the entire national road system; that tourism was the growth industry of the province. The general's son spoke slow and beautiful French and it clearly gave him great pleasure to hear himself, for he kept his eyes half closed and smiled as he spoke, as if listening to beloved music.

'I may conclude, monsieur, with a word of warning to your country. You are American?'

'English,'

'It is the same. Tell your government, sir. If you do not help us to continue the fight against the Communists, we shall go to the Russians and ask them to replace you in our struggle.'

Oh, mother, thought Jerry. Oh boy. Oh God.

'I will give them that message,' he promised, and made to go.

'Un instant. monsieur,' said the senior official sharply, and there was a stirring among his dozing courtiers. He opened a drawer and pulled out an imposing folder. Frost's will, Jerry thought. My death warrant. Stamps for Cat.

'You are a writer?'

'Yes.'

Ko's putting the arm on me. The pen tonight, and wake up with my throat cut tomorrow.

'You were at the Sorbonne, monsieur?' the official enquired.

'Oxford.'

'Oxford in London?'

'Yes.'

'Then you have read the great French poets, monsieur?'

'With intense pleasure,' Jerry replied fervently. The courtiers were looking extremely grave.

'Then perhaps monsieur will favour me with his opinion of the following few verses.' In his dignified French, the little official began to read aloud, slowly conducting with his palm.

'Deux amants assis sur la terre.

Regardaient la mer,'

he began, and continued for perhaps twenty excruciating lines while Jerry listened in mystification.

'Voila,' said the official finally, and put the file aside. 'Vous l'aimez?' he enquired, severely fixing his eye upon a neutral part of the room.

'Superbe,' said Jerry with a gush of enthusiasm. 'Merveilleux. The sensitivity.'

'They are by whom would you think?'

Jerry grabbed a name at random. 'By Lamartine?'

The senior official shook his head. The courtiers were observing Jerry even more closely.

'Victor Hugo?' Jerry ventured.

'They are by me,' said the official and with a sigh returned his poems to the drawer. The courtiers relaxed. 'See that this literary person has every facility,' he ordered.

Jerry returned to the airport to find it a milling, dangerous chaos. Mercedes raced up and down the approach as if someone had invaded their nest, the forecourt was a turmoil of beacons, motorcycles and sirens; and the hall, when he argued his way through the cordon, was jammed with scared people fighting to read noticeboards, yell at each other and hear the blaring loudspeakers all at the same time. Forcing a path to the information desk, Jerry found it closed. He leapt on the counter and saw the airfield through a hole in the anti-blast board. A squad of armed soldiers was jog-trotting down the empty runway toward a group of white poles where the national flags drooped in the windless air. They lowered two of the flags to half mast, and inside the hall the loudspeakers interrupted themselves to blare a few bars of the national anthem. Over the seething heads, Jerry searched for someone he might talk to. He selected a lank missionary with cropped yellow hair and glasses and a six-inch silver cross pinned to the pocket of his brown shirt. A pair of Cambodians in dog-collars stood miserably beside him.

'Vous parlez francais?'

'Yes, but I also speak English!'

A lilting, corrective tone. Jerry guessed he was a Dane.

'I'm press. What's the fuss?' He was shouting at the top of his voice.

'Phnom Penh is closed,' the missionary bellowed in reply. 'No planes may leave or land.'

'Why?'

'Khmer Rouge have hit the ammunition dump in the airport. The town is closed till morning at the least.'

The loudspeaker began chattering again. The two priests listened. The missionary stooped nearly double to catch their murmured translation.

'They have made a great damage and devastated half a dozen planes already. Oh yes! They have laid them waste entirely. The authority is also suspecting sabotage. Maybe she also takes some prisoners. Listen, why are they putting an ammunition house inside the airport in the first case? That was most dangerous. What is the reason here?'

'Good question,' Jerry agreed.

He ploughed across the hall. His master plan was already dead, as his master plans usually were. The 'crew only' door was guarded by a pair of very serious crushers and in the tension he saw no chance of brazening his way through. The thrust of the crowd was toward the passenger exit, where harassed ground staff were refusing to accept boarding tickets, and harassed police were being besieged with letters of laissez passer designed to put the prominent outside their reach. He let it carry him. At the edges, a team of French traders was screaming for a refund, and the elderly were preparing to settle for the night. But the centre pushed and peered and exchanged fresh rumours, and the momentum carried him steadily to the front. Reaching it, Jerry discreetly took out his cable card and climbed over the improvised barrier. The senior policeman was sleek and well-covered and he watched Jerry disdainfully while his subordinates toiled. Jerry strode straight up to him, his shoulder bag dangling from his hand, and pressed the cable card under his nose.

'Securite americaine,' he roared in awful French, and with a snarl at the two men on the swing doors, barged his way on to the tarmac and kept going, while his back waited all the time for a challenge or a warning shot or, in the trigger-happy atmosphere, a shot that was not even a warning. He walked angrily, with rough authority, swinging his shoulder bag, Sarratt-style, to distract. Ahead of him - sixty yards, soon fifty - stood a row of single-engined military trainers without insignia. Beyond lay the caged enclosure, and the freight huts, numbered nine to eighteen, and beyond the freight huts Jerry saw a cluster of hangars and park bays, marked prohibited in just about every language except Chinese. Reaching the trainers, Jerry strode imperiously along the line of them as if he were carrying out an inspection. They were anchored with bricks on wires. Pausing but not stopping, he stabbed irritably at a brick with his buckskin boot, yanked at an aileron and shook his head. From their sandbagged emplacement, to his left, an anti-aircraft guncrew watched him indolently.

'Qu'est-ce que vous faites?'

Half turning, Jerry cupped his hands to his mouth. 'Watch the damn sky for Christ's sakes,' he yelled in good American; pointing angrily to heaven, and kept going till he reached the high cage. It was open and the huts lay ahead of him. Once past them he would be out of sight of both the terminal and the control tower. He was walking on smashed concrete with couch-grass in the cracks. There was nobody in sight. The huts were weather-board, thirty feet long, ten high, with palm roofs. He reached the first. The boarding on the windows read 'Bomb Cluster Fragmentation Without Fuses'. A trodden dust-path led to the hangars on the other side. Through the gap Jerry glimpsed the parrot colours of parked cargo planes.

'Got you,' Jerry muttered aloud, as he emerged on the safe side of the huts, because there ahead of him, clear as day, like a first sight of the enemy after months of lonely marching, a battered blue-grey Dc4 Carvair, fat as a frog, squatted on the crumbling tarmac with her nose cone open. Diesel oil was dripping in a fast black rain from both her starboard engines and a spindly Chinese in a sailing cap laden with military insignia stood smoking under the loading bay while he marked an inventory. Two coolies scurried back and forth with sacks, and a third worked the ancient loading lift. At his feet, chickens scrabbled petulantly. And on the fuselage, in flaming crimson against Drake Ko's faded racing colours, ran the letters OCHART. The others had been lost in a repair job.

Oh, Charlie's indestructible, completely immortal! Charlie Marshall, Mr Tiu, a fantastic half Chinese, all skin and bones and opium and a completely brilliant pilot...

He'd bloody well better be, sport, thought Jerry with a shudder, as the coolies loaded sack after sack through the open nose and into the battered belly of the plane.

The Reverend Ricardo's lifelong Sancho Panza, your Grace, Craw had said, in extension of Lizzie's description. Half Chow, as the good lady advised us, and the proud veteran of many futile wars.

Jerry remained standing, making no attempt to conceal himself, dangling the bag from his fist and wearing the apologetic grin of an English stray. Coolies now seemed to be converging on the plane from several points at once: there were many more than two. Turning his back on them, Jerry repeated his routine of strolling along the line of huts, much as he had walked along the line of trainers, or along the corridor toward Frost's room, peering through cracks in the weatherboard and seeing nothing but the occasional broken packing case. The concession to operate out of Battambang costs half a million US renewable, Keller had said. At that price, who pays for redecoration? The line of huts broke and he came on four army lorries loaded high with fruit, vegetables and unmarked gunny bags. Their tailboards faced the plane and they sported artillery insignia. Two soldiers stood in each lorry handing the gunny bags down to the coolies. The sensible thing would have been to drive the lorries on to the tarmac, but a mood of discretion prevailed. The army likes to be in on things, Keller had said. The navy can make millions out of one convoy down the Mekong, the air force is sitting pretty: bombers fly fruit and the choppers can airlift the rich Chinese instead of the wounded out of the siege towns. Fighter boys go a little hungry because they have to land where they take off. But the army really has to scratch around to make a living.

Jerry was closer to the plane now and could hear the squawking as Charlie Marshall fired commands at the coolies.

The huts began again. Number eighteen had double doors and the name Indocharter daubed in green down the woodwork, so that from any distance the letters looked like Chinese characters. In the gloomy interior, a Chinese peasant couple squatted on the dust floor. A tethered pig lay with its head on the old man's slippered foot. Their other possession was a long rush parcel meticulously bound with string. It could have been a corpse. A water jar stood in one corner with two rice bowls at its base. There was nothing else in the hut. 'Welcome to the Indocharter transit lounge,' Jerry thought. With the sweat running down his ribs, he tagged himself to the line of coolies till he drew alongside Charlie Marshall, who went on squawking in Khmer at the top of his voice while his shaking pen checked each load on the inventory.

He wore an oily white short-sleeved shirt with enough gold stripes on the epaulettes to make a full general in anybody's air force. Two American combat patches were stitched to his shirt front, amid an amazing collection of medal ribbons and Communist red stars. One patch read 'Kill a Commie for Christ', and the other 'Christ was a Capitalist at Heart'. His head was turned down and his face was in the shadow of his huge sailing cap, which slopped freely over his ears. Jerry waited for him to look up. The coolies were already yelling for Jerry to move on, but Charlie Marshall kept his head turned stubbornly down while he added and wrote on the inventory and squawked furiously back at them.

'Captain Marshall, I'm doing a story on Ricardo for a London newspaper,' said Jerry quietly. 'I want to ride with you as far as Phnom Penh and ask you some questions.'

As he spoke, he gently laid the volume of Candide on top of the inventory, with three one-hundred dollar bills poking outward in a discreet fan. When you want a man to look one way, says the Sarratt school of illusionists, always point him in the other.

'They tell me you like Voltaire,' he said.

'I don't like anybody,' Charlie Marshall retorted in a scratchy falsetto at the inventory, while the cap slipped still lower over his face. 'I hate the whole human race, hear me?' His vituperation, despite its Chinese cadence, was unmistakably French-American. 'Jesus Christ, I hate mankind so damn much that if it don't hurry and blow itself to pieces I'm personally going to buy some bombs and go out there myself!'

He had lost his audience. Jerry was halfway up the steel ladder before Charlie Marshall had completed his thesis.

'Voltaire didn't know a damn bloody thing!' he screamed at the next coolie. 'He fought the wrong damn war, hear me? Put it over there you lazy coon and grab another handful! Depeche-toi, cretin, oui?'

But all the same he jammed Voltaire into the back pocket of his baggy trousers.

The inside of the plane was dark and roomy and cool as a cathedral. The seats had been removed, and perforated green shelves like Meccano had been fitted to the walls. Carcasses of pig and guinea fowl hung from the roof. The rest of the cargo was stowed in the gangway, starting from the tail end, which gave Jerry no good feeling about taking off, and consisted of fruit and vegetables and the gunny bags which Jerry had spotted in the army trucks, marked 'grain', 'rice', 'flour', in letters large enough for the most illiterate narcotics agent to read. But the sticky smell of yeast and molasses which already filled the hold required no labels at all. Some of the bags had been arranged in a ring, to make a sitting area for Jerry's fellow passengers. Chief of these were two austere Chinese men, dressed very poorly in grey, and from their sameness and their demure superiority Jerry at once inferred an expertise of some kind. He remembered explosives-wallahs and pianists he had occasionally ferried thanklessly in and out of badland. Next to them, but respectfully apart, four hills men armed to the teeth sat smoking, and cropping from their rice bowls. Jerry guessed Meo or one of the Shan tribes from the northern borders where Charlie Marshall's father had his army, and he guessed from their ease that they were part of the permanent help. In a separate class altogether sat the quality: the colonel of artillery himself, who had thoughtfully supplied the transport and the troop escort, and his companion a senior officer of customs, without whom nothing could have been achieved. They reclined regally in the gangway, on chairs specially provided, watching proudly while the loading continued, and they wore their best uniforms as the ceremony demanded.

There was one other member of the party and he lurked alone on top of the cases in the tail, head almost against the roof, and it was not possible to make him out in any detail. He sat with a bottle of whisky to himself, and even a glass to himself. He wore a Fidel Castro hat and a full beard. Gold links glittered on his dark arms, known in those days (to all but those who wore them) as CIA bracelets, on the happy assumption that a man ditched in hostile country could buy his way to safety by doling out a link at a time. But his eyes, as they watched Jerry along the well-oiled barrel of an AK47 automatic rifle, had a fixed brightness. 'He was covering me through the nose cone,, thought Jerry. 'He had a bead on me from the moment I left the hut.'

The two Chinese were cooks, he decided in a moment of inspiration: cooks being the underworld nickname for chemists. Keller had said that the Air Opium lines had taken to bringing in the raw base and refining it in Phnom Penh, but were having hell's own job persuading the cooks to come and work in siege conditions.

'Hey you! Voltaire!'

Jerry hurried forward to the edge of the hold. Looking down he saw the old peasant couple standing at the bottom of the ladder and Charlie Marshall trying to wrench the pig from them while he shoved the old woman up the steel ladder.

'When she come up you gotta reach out and grab her, hear me?' he called, holding the pig in his arms. 'She fall down and break her ass we gotta whole lot more trouble with the coons. You some crazy narcotics hero, Voltaire?'

'No.'

'Well, you grab hold of her completely, hear me?'

She started up the ladder. When she had gone a few rungs she began croaking and Charlie Marshall contrived to get the pig under his arm while he gave her a sharp crack on the rump and screamed at her in Chinese. The husband scurried up after her and Jerry hauled them both to safety. Finally Charlie Marshall's own clown's head appeared through the cone, and though it was swamped by the hat, Jerry had his first glimpse of the face beneath: skeletal and brown, with sleepy Chinese eyes and a big French mouth which twisted all ways when he squawked. He shoved the pig through, Jerry grabbed it and carted it, screaming and wriggling, to the old peasants. Then Charlie hauled his own fleshless frame aboard, like a spider climbing out of a drain. At once, the officer of customs and the colonel of artillery stood up, brushed the seats of their uniforms, and progressed swiftly along the gangway to the shadowed man in the Castro hat squatting on the packing cases. Reaching him, they waited respectfully, like sidesmen taking the offertory to the altar.

The linked bracelets flashed, an arm reached down, once, twice, and a devout silence descended while the two men carefully counted a lot of bank notes and everybody watched. In rough unison they returned to the top of the ladder where Charlie Marshall waited with the manifest. The officer of customs signed it, the colonel of artillery looked on approvingly, then they both saluted and disappeared down the ladder. The nose cone juddered to an almost-closed position, Charlie Marshall gave it a kick, flung some matting across the gap, and clambered quickly over the packing cases to an inside stairway leading to the cabin. Jerry clambered after him, and having settled himself into the co-pilot's seat, he silently totted up his blessings.

'We're about five hundred tons overweight. We're leaking oil. We're carrying an armed bodyguard. We're forbidden to take off. We're forbidden to land, Phnom Penh airport's probably got a hole the size of Buckinghamshire. We have an hour and a half of Khmer Rouge between us and salvation, and if anybody turns sour on us the other end, ace operator Westerby is caught with his knickers round his ankles and about two hundred gunny bags of opium base in his arms.'

'You know how to fly this thing?' Charlie Marshall yelled, as he struck at a row of mildewed switches. 'You some kinda great flying hero, Voltaire?'

'I hate it all.'

'Me too.'

Seizing a swat, Charlie Marshall flung himself upon a huge bottle-fly that was buzzing round the windscreen, then started the engines one by one, until the whole dreadful plane was heaving and rattling like a London bus on its last journey home up Clapham Hill. The radio crackled and Charlie Marshall took time off to give an obscene instruction to the control tower, first in Khmer and afterwards, in the best aviation tradition, in English. Heading for the far end of the runway, they passed a couple of gun emplacements and for a moment Jerry expected an overzealous crew to loose off at the fuselage, till in gratitude he remembered the army colonel and his lorries and his pay-off. Another bottle-fly appeared and this time Jerry took possession of the fly swat. The plane seemed to be gathering no speed at all, but half the instruments read zero so he couldn't be sure. The din of the wheels on the runway seemed louder than the engines. Jerry remembered old Sambo's chauffeur driving him back to school: the slow, inevitable progress down the Western by-pass toward Slough and finally Eton.

A couple of the hills men had come forward to see the fun and were laughing their heads off. A clump of palm trees came hopping toward them but the plane kept its feet firmly on the ground. Charlie Marshall absently pulled back the stick and retracted the landing gear. Uncertain whether the nose had really lifted, Jerry thought of school again, and competing in the long jump, and recalled the same sensation of not rising, yet ceasing to be on the earth. He felt the jolt and heard the swish of leaves as the underbelly cropped the trees. Charlie Marshall was screaming at the plane to pull itself into the damn air, and for an age they made no height at all, but hung and wheezed a few feet above a winding road which climbed inexorably into a ridge of hills. Charlie Marshall was lighting a cigarette so Jerry held the wheel in front of him and felt the live kick of the rudder. Taking back the controls, Charlie Marshall pointed the plane into a slow bank at the lowest point of the range. He held the turn, crested the range and went on to make a complete circle. As they looked down on the brown rooftops and the river and the airport, Jerry reckoned they had an altitude of a thousand feet. As far as Charlie Marshall was concerned, that was a comfortable cruising height, for now at last he took his hat off and, with the air of a man who had done a good job well, treated himself to a large glass of Scotch from the bottle at his feet. Below them dusk was gathering, and the brown earth was fading softly into mauve.

'Thanks,' said Jerry, accepting the bottle. 'Yes, I think I might.'
