You've pulled the curtain round so well.'

David nodded. He was wondering whether he could trust himself to answer the fellow, for it was obvious that his own ident.i.ty was not even suspected. Then, emboldened by that fact, he answered the man in a hoa.r.s.e whisper.

'I came along out here to make sure. It's fine, ain't it? Them police couldn't suspect that we'd got a hot flame going against the safe. Look here, my boy, Henricksen wants you to go along up to Ovanovitch and give him a hand. When you've cleared the jewels, get away up to the next floor. He says some new furs came in yesterday, and you could carry away in your arms enough to keep you for a year. Get along quick.'

The Russian looked at him for a moment as if he suspected, though, as a matter of fact, he was merely puzzling to translate the meaning of the words, for as yet he was not an excellent English scholar.

'Get along up and help Ovanovitch, yes,' he repeated. 'Then--I did not follow--you said?'

'S-s-sh! The police!'

There came a sudden rattle at the letter-box, whereat both he and the Russian sank promptly to the ground, while David imagined that a faint light over by the office lessened. Then there was silence again. A heavy footfall was heard on the pavement, and after it, silence once more.

Slowly he and the Russian rose to their feet.

'What was it?' asked the man. 'You said I was to help Ovanovitch.'

'Listen,' whispered David, speaking very plainly, 'help Ovanovitch with the jewels.'

'Yes, yes; I have that'

'Then take him to the floor up above.'

'Floor up above. Yes, yes; I have that too.'

'Where you will find some valuable furs brought in only yesterday.'

'Only yesterday, furs; valuable furs. Yes; go on.'

'You can carry enough away on your arm to make you rich for a year. Got it?'

Spolikoff nodded vigorously, and gave expression to some guttural words of approval.

'Now?' he asked. 'You watch here?'

'Yes,' said David, 'Go at once; no need to hurry back.'

His hand was shaking ever so little as he took the Russian by the sleeve and urged him towards the stairs; for the feeble light above the place had suddenly shown him another figure. The man was descending the stairs, and was almost at the bottom. David could see that a bundle was suspended over his back. It was Ovanovitch without doubt, descending now that his task was completed.

'Tell him; go up at once,' David managed to whisper, though his tongue almost stuck to the roof of his mouth. 'I am going back to Henricksen.'

He slid off at once, slipped behind a huge showcase, and then stared back through the gla.s.s at the two Russians. And as he did so the tight feeling about his chest and neck slowly lessened. He drew in the first comfortable breath he had taken for some minutes. A sigh almost escaped him; for Spolikoff had been absolutely deceived. It was clear that he was not in the smallest degree suspicious. He had taken our hero for the Admiral, and was obeying instructions in a manner almost child-like. He went at once to Ovanovitch, and for a few seconds they whispered on the stairs. Then they turned their backs to the ground floor and went up two steps at a time, as if eager to get to their destination.

'Got 'em,' David could have shouted, though he restrained himself, hugging his arms instead. 'Got 'em, I do believe. Now for the rest of the business.' His brain had been working hard in the last few minutes, and already he had mapped out a course of procedure. After all, that was exactly like the young fellow; his friends knew him to be exceedingly practical. Edward Harbor, his father, had endeavoured to train his boy to conduct matters of any moment with sense and discretion.

'Decide first of all what you're going to do,' he had often said. 'Don't start without a plan, all haphazard, and find when you are half way through that matters aren't promising. Stand away a bit, as it were, and have a clear view; then make your plans, and set to at the business.' Practical? Of course it was. Common sense management? Who can doubt it? A little advanced for one of David's age? Certainly, if you wish so to describe it. But that is worth remedying. Others can be trained as our hero had been, and the training has its undoubted advantages; for a practical young fellow is of infinitely greater value in these strenuous days than a lad always wool-gathering, who lacks energy and initiative, who begins a task only to fail, who succeeds only where a course of procedure has been already laid down, and when previous practice has made perfect. It is the uncertainties we want to train our lads to face, as well as the hum-drum certainties of this life.

'Got 'em,' David e.j.a.c.u.l.a.t.ed again, in a deep whisper. 'Now to close the holes and divide the conspirators. First downstairs--that is the main burrow I have to see to.'

He had lost all his trepidation now. True, he was more than a little excited; but his hand no longer shook. He had seen already the possibilities of making a gigantic success of what had at first appeared to be an enormously difficult task. Straightway he stole across to the stairway leading to the bas.e.m.e.nt, and tripped down three steps at a time. Then he ran across to the cupboard through which the four men had gained access to the store. Out came his electric torch, and a beam was flashed into the interior.

'As I thought: these fellows must have hired a house or a room in one of the buildings lying up against this place, and have knocked a hole clean through the wall. Then they cut through the back of the cupboard.

No; no they didn't; they bored holes through the wood in a big circle, and so managed to remove a piece without making a sound. If they had employed a saw I should have heard them. Now, I shut the cupboard, and lock the door.'

It was not a flimsy affair, this cupboard, but a strongly built piece of furniture, firmly attached to the wall, and having doors which slid along in grooves. David gently moved the doors into place, found a key in the lock, and shot the bolt to. Then he tried to open the cupboard.

It was closed and defied his efforts.

'Number one loop hole gone,' he said. 'Now for the warning and number two.'

He had planned out the whole course of movement, and came hopping up the stairs again, three at a time. A quick glance told him that the oxy-acetylene flame was still in use. A dull glow on the ceiling told its tale without shadow of error, while as he listened a gentle buzz came to his ear. From the upper floor there was not so much as a sound.

At once he crossed to the door, and pulled the flap of the letter-box open. Click! Down went the glare over by the manager's office. Lying p.r.o.ne on the floor, and staring in that direction, David saw a man's head protruding from the opening. Then the fellow stepped out and stood listening. A whisper came to his ear, and at once the Admiral--for he it was without doubt--slid back into the manager's office to help in the task of forcing the safe. The reflection on the ceiling told its tale again promptly.

'Out with the life preserver, and then upstairs,' said David. 'No time to wait; those fellows will have found their furs by now.'

Very craftily he pushed the end of the life preserver through the flap, and left it wedged in position. Then he ran across the floor to the stairs and raced up them. Pa.s.sing the first floor, he was soon at the entrance to the second. And as he reached it his eyes fell on the two figures of the Russians. They were staggering along the centre pa.s.sage between the gla.s.s show cases, their arms piled with furs. They were thirty paces away, perhaps, whispering as they came.

Dare he do it? Dare he pull the door of this portion of the store to in their faces?

David closed his teeth with a firm click; his chin a.s.sumed that very bulldog squareness for which he was notorious. He stepped coolly into the opening, gripped the iron fire door, with which the entrance to every one of the departments of the store was furnished, and brought it to with a bang. The hand-operated latch went to its socket with a scrunch. The door was fast. Number two loop hole was closed. The burglars were inevitably separated.

'And now for the last move.'

Conscious that the noise he had made might well have reached Henricksen, and yet hopeful that it had not done so, David descended the stairs faster than ever before in his life. He reached the ground floor just as a sound came from the letter-box. He fancied he heard voices outside. He was sure that the oxy-acetylene flame was working, and at that second watched as its reflection seemed to be wiped away from the ceiling above the manager's office. Then he did a smart thing. He opened the outside doors of the lift with a bang, leaped in, and ran the elevator up till it was half way through the gap leading to the first floor. He brought it to a rest there with a sudden jerk, and throwing himself flat on its floor, levelled his weapon at the door of the manager's office. And by then there was a commotion in that direction. Two figures come helter-skelter from the opening, their hands held before them, their smoked gla.s.ses already torn from their faces. At the same instant there came the sound of a key in a lock, and then the main entrance of the store was burst open.

'Stop there, Henricksen and the Admiral!' David shouted. 'Stop where you are or I fire. Constable, hold the door, I have closed the other places.'

Ping! Bang! From some point up above our hero, there came a revolver shot, and he heard the missile thud against the roof of the elevator and tinkle on to the floor near him. Ping! A second came, and then he felt the elevator moving. It was ascending. Some one had put it into operation from above. At once he guessed what had happened. The two Russians, shut into the fur department, had heard the lift working. They had torn the doors open, and reaching through had gripped the rope by means of which it was operated. David at one sprang to his feet and gripped the handle which operated the rope. Instantly he brought the machine to a stop, and turning the handle again, brought the elevator back to its former position, a shot coming from above as he did so.

Then he cast his eyes into the store, and at once took in the position, which had altered in the s.p.a.ce of a few seconds. There were two constables at the door, Hemming and another, the latter of whom was at that moment l.u.s.tily blowing his whistle. At the entrance to the stairs leading to the bas.e.m.e.nt stood the Admiral, a revolver in his hands, while the other rascal was nowhere visible; but a minute later he came racing up the stairs, and burst into the department.

'Give me the shooter,' he cried, breathlessly. 'They've shut the cupboard below and boxed us in. Give it me. I'm not afraid to use it.'

He seized the weapon from his comrade's hand, and in an instant there was a flash. The constable blowing his whistle staggered into the doorway. David at once leaned forward, levelled his own weapon, and pulled on the trigger. And in the s.p.a.ce of a second he had ejected three bullets in the direction of Henricksen; for his was an automatic pistol, the cla.s.s of weapon that wants careful controlling, and which will fire seven shots in less number of seconds, automatically moving a fresh cartridge into position after each shot. Certainly the bullets astounded David, and Henricksen also. He swung round, and then our hero knew what it was to be under fire. Something hissed past his cheek. The hair on his head stirred restlessly. A red-hot brand appeared to have been of a sudden thrust right through his body. But he was game to the last. He leaned over a little, fixed his revolver sights as well as he was able, and pressed his trigger again.

An instant later Henricksen went staggering up against one of the gla.s.s show cases. He upset the whole affair, and came crashing to the floor with gla.s.s smashing and splintering all about him; then his comrade darted forward, and stooped to pick up the weapon which he had dropped.

'Stand away from that place,' David commanded hoa.r.s.ely. 'I'll drop you, Admiral, as sure as you move a step. Now, hands up above your head.'

'Admiral, Admiral, what's that?' came from the doorway. 'Where are you, David Harbor?'

'In the lift, half way up,' our hero called out, wondering vaguely at the weakness of his own voice. 'Half way up, Hemming. The man who fired at you, and whom I have just sent down is Henricksen, one of the employees here. The fellow with his arms up is known as the Admiral.'

'Phew.' There came a shrill whistle from Hemming. 'The Admiral did you say? Wanted in a dozen capitals. Swindler, forger, burglar, everything.'

'And two Russians upstairs, whom I have trapped in the fur department.

Now, Hemming, got those handcuffs?'

Feeling curiously shaky David touched the handle of the lift again, and brought it down to the floor level, unmindful of the shots which still came from above. And all the while he held his weapon directed at the man standing so close to Henricksen.

'Now, Hemming,' he called out. 'Shut the door, or he might try to bolt.

Slip the handcuffs on him; but first of all, switch on the lights just inside the door.'
