To go back meant death, and the loss of Beverley's papers. Besides, she had been seen. For once, Clo's wits refused to work. Like a frozen flower, she remained motionless in the window.
The figure in the doorway was that of a man. The light coming from behind made his face a blank for her eyes, but the girl saw that he was taller than O'Reilly and of a different build. Perhaps it was the owner of the suite, he who had gone out with the beautiful woman. The man made no move. He stood in the doorway as if rooted to the floor. "My God!" Clo heard him mutter.
"The fool takes me for a ghost," she thought. "Now's my chance, before he plucks up courage!"
Down came the other white shoe on the carpet with no more noise than a rose-petal falling. Then followed a second of indecision. Should she risk pushing the man aside, and fleeing past him into the hall? No, her touch would break the spell. She must go on with the ghost-play, and vanish in the dark!
Light from outside showed her the open door of an adjoining room. Thence came the draught which had set the curtains blowing. Clo took a few floating steps toward the man, then dodged aside, and disappeared into the room beyond. Softly she closed the communicating door and slid the bolt. Almost opposite where she stood opened a cross passage leading to a wing of the hotel. With a bound she reached it, not daring to look behind, yet listening with the ear of the hunted for the hunter, as she ran. Coming to a staircase the girl plunged down it two steps at a time. On the floor below, however, she ventured to moderate her pace. This was the dinner hour; most of the guests would be in the restaurant, or out of the hotel for the evening; but there would be servants about. Clo forced herself to descend sedately, flight after flight of stairs, not daring to enter a lift. At last, when it seemed that she had come to earth from the top of Jacob's ladder, the stairway ended. Timidly following a passage that opened before her, she ventured into a wide, important hall.
There was a cloakroom in the hall. Ladies were going into it and coming out. Clo heard music in the distance and saw a marble balustrade. This balustrade was for her a landmark. She knew by it that she must have reached the story above the ground floor, and that the large corridor of the cloakroom opened on to a gallery overlooking the main hall. She had glanced up and admired that marble balustrade when she first entered the hotel. She had seen also a wide marble staircase leading up to the gallery. It must be near, she thought, but it was a way of exit to avoid. If O'Reilly were on guard below, or even if he had merely telephoned her description to the office, she and the stolen envelope would be promptly nabbed in the hall below. She had dared too much to be tamely taken now. Mirrors were let into the panels of the wall, and Clo paused before one, pretending to straighten her hat. She wanted time to make up her mind.
