'Has the Captain here explained the situation to you yet?'

'He has.'

'And what do you think?'

'I don't think at all,' Devlin told him. 'Especially where you lot are concerned.'

'The purpose of terrorism is to terrorize, that's what Mick Collins used to say,' McGuiness told him. 'I fight for my country, Liam, with anything that comes to hand. We're at war.' He was angry now. 'I've got nothing to apologize for.'

'If I could say something,' Fox put in. 'Let's accept that Cuchulain exists, then it isn't a question of taking sides. It's accepting that what he's doing has needlessly protracted the tragic events of the past thirteen years.'

McGuiness helped himself to a whiskey. 'He has a point. When I was O.C. Derry in nineteen seventy-two, I was flown to London with Daithi O'Connell, Seamus Twomey, Ivor Bell and others to meet Willie Whitelaw to discuss peace.'

'And the Lenadoon shooting broke the cease-fire,' Fox said and turned to Devlin. 'It doesn't seem to me to be a question of taking sides any more. Cuchulain has worked deliberately to keep the whole rotten mess going. I would have thought anything that might have helped stop that would be worth it.'

'Morality is it?' Devlin raised a hand and smiled wickedly.

'Good then, let's get down to bra.s.s tacks. This fella, Levin, who actually saw Kelly or Cuchulain or whatever his name is, all those years ago. I presume Ferguson is showing him pictures of every known KGB operative.'

'And all known adherents of the IRA, UDA, UVF. Anything and everything,' Fox said. 'That will include looking at what Special Branch in Dublin have because we swop information.'

'The b.a.s.t.a.r.ds would,' McGuiness said bitterly. 'Still, I think we've got a few that neither the police in Dublin nor your people in London have ever seen.'

'And how do we handle that?' Fox demanded.

'You get Levin over here and he and Devlin look at what we've got - no one else. Is it agreed?'

Fox glanced at Devlin who nodded. 'Okay,' Fox said. Til ring the Brigadier tonight.'

'Fine.' McGuiness turned to Devlin. 'You're sure your phone's not tapped or anything like that. I'm thinking of those Special Branch b.a.s.t.a.r.ds.'

Devlin opened a drawer in the desk and produced a black metal box which he switched on so that a red light appeared. He approached the telephone and held the box over it. There was no reaction.

'Oh, the wonders of the electronic age,' he said and put the box away.

'Fine,' McGuiness said. 'The only people who know about this are Ferguson, you, Captain, Liam, the Chief of Staff and myself.'

'And Professor Paul Cherny,' Fox said.

McGuiness nodded. 'That's right. We've got to do something about him.' He turned to Devlin. 'Do you know him?'

'I've seen him at drinks parties at the university. Exchanged a civil word, no more than that. He's well liked. A widower.

His wife died before he defected. There's a chance he isn't involved in this, of course.'

'And pigs might fly,' McGuiness said crisply. 'The fact that it was Ireland he defected to is too much of a coincidence for me. A pound to a penny he knows our man, so why don't we pull him in and squeeze it out of him?'

'Simple,' Fox told him. 'Some men don't squeeze.'

'He's right,' Devlin said. 'Better to try the softly-softly approach first.'

'All right,' McGuiness said. Til have him watched twenty-four hours a day. Put Michael Murphy in charge. He won't be able to go to the bathroom without we know it.'

Devlin glanced at Fox. 'Okay by you?'

'Fine,' Fox told him.

'Good.' McGuiness b.u.t.toned his raincoat. Til get off then. I'll leave Billy to look after you, Captain.' He opened the French window. 'Mind your back, Liam.' And then he was gone.

Ferguson was in bed when Fox phoned, sitting up against the pillows, working his way through a ma.s.s of papers, preparing himself for a Defence committee meeting the following day. He listened patiently to everything Fox had to say. 'So far, so good, Harry, as far as I can see. Levin spent the entire day working through everything we had at the Directorate. Didn't come up with a thing.'

'It's been a long time, sir. Cuchulain could have changed a lot and not just because he's older. I mean, he could have a beard, for example.'

'Negative thinking, Harry. I'll put Levin on the morning flight to Dublin, but Devlin will have to handle him. I need you back here.'

'Any particular reason, sir?'

'Lots to do with the Vatican. It really is beginning to look as if the Pope won't come. However, he's invited the cardinals of Argentina and Britain to confer with him.'

'So the visit could still be on?'

'Perhaps, but more.important from our point of view, the

war is still on and there's talk of the Argentinians trying to get hold of this d.a.m.ned Exocet missile on the European black market. I need you, Harry. Catch the first flight out. By the way, an interesting development. Tanya Voroninova, remember her?'

'Of course, sir.'

'She's in Paris to give a series of concerts. Fascinating that she should surface at this particular moment.'

'What Jung would call synchronicity, sir?'

'Young, Harry? What on earth are you babbling about?'

'Carl Jung, sir. Famous psychologist. Synchronicity is a word he coined for events having a coincidence in time and, because of this, the feeling that some deeper motivation is involved.'

'The fact that you're in Ireland is no excuse for acting as if you've gone soft in the head, Harry,' Ferguson said testily.

He put down the phone, sat there thinking, then got up, pulled on his robe and went out. He knocked on the door of the guest room and went in. Levin was sitting up in bed wearing a pair of Ferguson's pyjamas and reading a book.

Ferguson sat on the edge of the bed. 'I thought you'd be tired after going through so many photos.'

Levin smiled. 'When you reach my age, Brigadier, sleep eludes you, memory crowds in. You wonder what it has all been about.'

Ferguson warmed to the man. 'Don't we all, my dear chap? Anyway, how would you feel about running over to Dublin on the morning plane?'

'To see Captain Fox?'

'No, he'll be returning here, but a friend of mine, Professor Liam Devlin of Trinity College, will take care of you. He'll probably be showing you a few more photos, courtesy of our friends in the IRA. They'd never let me have them for obvious reasons.'
