Usually, no one would identify the Grand Empire Hotel with crime and intrigue; but that did not deter Gurdon from rising from his bed and making a determined effort to see through the ventilator into the adjoining room. It was not an easy matter, but by dint of balancing two chairs one on top of the other the thing was accomplished. Very cautiously Gurdon pushed back the glass slide and looked through. So far as he could see, there was nothing to justify any suspicion. The room was absolutely empty, though it was brilliantly lighted; and for a moment Gurdon felt ashamed of his suspicions, and turned away, half determined to try and sleep. It was at that instant that he noticed something out of the common. To his quickened ear there came a sound unmistakably like a snore, and pushing his body half through the ventilator he managed to make out the bed in the next room. On it lay the body of a boy in uniform, unmistakably a messenger boy or hotel attendant of that kind. Gurdon could see the hotel name embroidered in gold letters on his collar. Perhaps there was nothing so very suspicious in this, except that the boy was lying on the bed fully dressed, even to his boots. It was a luxurious room; not at all the class of apartment to which the hotel management would relegate one of their messenger boys, nor was it possible that the lad had had the temerity to go into the vacant room and sleep. "Something wrong here," Gurdon muttered. "Hang me if I don't get through the ventilator and see what it is." 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.
