'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. Passing 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 passage between the glass 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 assumed 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 glasses 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 space of a few seconds. There were two constables at the door, Hemming and another, the latter of whom was at that moment lustily blowing his whistle. At the entrance to the stairs leading to the basement 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 space of a second he had ejected three bullets in the direction of Henricksen; for his was an automatic pistol, the class 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.
