Clo had been able to think very clearly, while there had been something definite to think about, but her brain refused this problem of an extra five minutes, which might mean success or failure. She couldn't stop where she was; she couldn't hang about in the street, lest the real Kit had given the false Kit away to the "gang"; yet to dawdle in the corridor, or on the stairs of the Westmorland Hotel, was unthinkable. When the murder of Peterson was discovered someone might remember that slim girl in brown. The police were diabolically clever--now and then. Who could say if they might not trace that girl in brown, and, finding her, eventually reach Beverley Sands? "One minute must have gone, just while I've been thinking of it!" Clo told herself. "And Peterson hasn't come alive. Now, if I can only think hard enough, and forget him and the silence, for two or three minutes, I can start." But the silence broke. Once more her nerves thrilled to the telephone bell. She was standing by the door, her back resolutely turned to the figure in the chair, when the sound began. The girl snatched the receiver and called "Hello" but no one answered. She must get out quickly, at the risk of having to wait in the street before O'Reilly could arrive. "Unless they live close by, they won't have had time to reach me yet, even if Kit's given the show away," Clo thought. But of course, "Chuff" might have 'phoned from a house round the corner. Peterson might have chosen the Westmorland Hotel in order to be near his friends! Clo locked the door, took out the key, and dropped it behind the trunk at the end of the hall. That would not be unfair to the owner of the trunk, she thought, for in any case, the blood stains would direct suspicion to Peterson's vanished neighbour. The key would be only a detail. As she descended the stairways leading from the sixth story to the ground floor, she met two or three men, but they had the air of tired commercial travellers going up to bed. Apparently the veiled girl in brown had no special interest for them. Next came the ordeal of the entrance hall, and passing the desk; but there a new group of men had collected. Clo peered through her brown veil, but encountered no curious glances. Yet the worst was to come. The eight minutes could hardly have run out; besides, O'Reilly might be late. If "Kit" were true to her pals, and if she had seen from her hiding place in the trunk, who went into Peterson's room, the coming moment might hold the greatest peril of all. The girl hesitated at the door, then sprang into the street as she might have sprung into a wave.
