Gurdon fell in readily enough with the suggestion. Indeed, there was nothing else for it. He took his number and key from the sleepy clerk in the office, and made his way upstairs to Venner's bedroom.
"I'll just have one cigarette before I turn in," he said. "It seems as if Fate had ordained that I am to keep in close touch with the leading characters of the mystery. By the way, we never took the trouble to find out who the handsome cripple was."
"That is very easily done in the morning," Venner replied. "A striking personality like that is not soon lost sight of. Besides, he has doubtless been here before, for, if you will recollect, his attendants took him to the right table as if it had been ordered beforehand. And now, if you don't mind, I'll turn in—not that I expect to sleep much after an exciting evening like this. Good night, old fellow."
Gurdon went on to his own room, where he slowly undressed and sat thinking the whole thing out on the edge of his bed. Perhaps he was suffering from the same suppressed excitement which at that moment was keeping Venner awake, for he felt not the slightest disposition to turn in. Usually he was a sound sleeper; but this night seemed likely to prove an exception to the rule.
An hour passed, and Gurdon was still sitting there, asking himself whether it would not be better to go to bed and compel sleep to come to him. Impatiently he turned out his light and laid his head resolutely on the pillow.
But it was all in vain—sleep was out of the question. The room was not altogether in darkness, either; for the sleeping apartments on that landing had been arranged back to back with a large, open ventilator between them. Through this ventilator came a stream of light; evidently the occupant of the adjoining room had not yet retired. The light worried Gurdon; he asked himself irritably why his neighbor should be permitted to annoy him in this way. A moment or two later the sound of suppressed voices came through the ventilator, followed by the noise of a heavy fall.
At any ordinary time Gurdon would have thought nothing of this, but his imagination was aflame now, and his mind was full of hidden mysteries. It seemed to him that something sinister and underhand was going on in the next room.
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."
