It was no difficult matter for an athlete like Gurdon to push his way through and drop on to the bed on the other side. Then he shook the form of the slumbering lad without reward. The boy seemed to be plunged in a sleep almost like death. As Gurdon turned him over, he noticed on the other side of the lad's collar the single word "Lift." It began to dawn upon Gurdon exactly what had happened. In large hotels like the Grand Empire there is no fixed period when the lift is suspended, and consequently, it has its attendants night and day. For some reason, this boy had evidently been drugged and carried into the room where he now lay. There was no doubt whatever about it, for it was impossible to shake the lad into the slightest semblance of life. Gurdon crossed to the door, and found, not to his surprise, that it was locked. His first impulse was to return to his room and call the night porter; but a strange, wild idea had come into his mind, and he refrained from doing so. It occurred to him that perhaps Mark Fenwick or the cripple had had a hand in this outrage.
"I'll wait a bit," Gurdon told himself. "It is just possible that my key will fit this door. Anyway, it is worth trying."
Gurdon made his way back to his own room again, to return a minute or two later with his key. To his great delight the door opened, and he stood in a further corridor, close against the cage in which the lift worked noiselessly up and down.
It was absolutely quiet, so that anybody standing there would have been able to carry out any operation of an unlawful kind without observation. Gurdon stood, looking down the lift shaft, until he saw that the cage was once more beginning to ascend. It came up slowly and smoothly and without the least noise, until it was level with the floor on which Gurdon was standing. It was one of the open kind, so he could see inside quite clearly. To all practical purposes, the lift was empty, save for the presence of one man, who lay unconscious on the floor. The cage was ascending so leisurely that Gurdon was in a position to make a close examination of the figure before the whole structure had risen to the next floor. It did not need a second glance to tell Gurdon that the man in the cage was the attendant, and that he was suffering from the same drug which had placed his boy assistant beyond all power of interfering.
"Now what does all this mean?" Gurdon muttered. "Who is there on the floor above who is interested in getting these two people out of the way? What do they want to bring up or send down which it is not safe to dispose of by the ordinary means? I think I'll wait and see. No sleep for me to-night."
The lift vanished in the same silent way. It hung overhead for some little time, and once more appeared in sight, this time absolutely empty, save for a small square box with iron bands at the corners, which lay upon the floor. As the cage descended, Gurdon suddenly made up his mind what to do. He sprang lightly on to the top of the falling cage, and grasped the rope with both hands. A moment later and he was descending in the darkness.
As far as he could judge, the lift went down to the basement, where, for the time being, it remained. There was a warm damp smell in the air, suggestive of fungus, whereby Gurdon judged that he must be in the vaults beneath the hotel. As his eyes became accustomed to the gloom, he could make out just in front of him a circular patch of light, which evidently was a coal shoot.
He had no need to wait now for the full development of the adventure. He could hear whispered voices and the clang of metal, as if somebody had opened the door of the lift. One of the voices he failed to understand, but with a thrill he recognised the fact that the speaker was talking in either Spanish or Portuguese. Instantly it flashed into his mind that this was the language most familiar to the man who called himself Mark Fenwick. Beyond doubt he was quite right when he identified this last development with the actors in the dramatic events earlier in the evening.
"Now don't be long about it," a hoarse voice whispered. "There are two more cases to send up, and two more to come down here. Has that van come along, or shall we have to wait until morning?"
"The van is there right enough," another hoarse voice said. "We have the stuff out on the pavement. Let's have the last lot here, and get it up at once."
