Dean Allison led the way downstairs quickly. Craig did not spend more than a minute in the gymnasium, but the locker-room he examined carefully.

It was a long room. Each locker bore the name of its owner and he hastily ran his eye over them, getting their location.

I don't know that even he had, yet, any idea that he would find anything, but it was just his habit to go over the ground of a tragedy, in hope of picking up some clew.

He looked over the floor very carefully, now and then bending down as if to discover spots. Once he paused a moment, then continued his measured tread down the long row of lockers until he came to a door at the other end of the room. We went out and Kennedy looked about closely.

"Oh,—about Benson, the steward," he said, looking up quickly and stroking his chin as if an idea had occurred to him. "Is there anyone here who might know something about him—his habits, associates,—that sort of thing?"

"Why—yes," considered Allison slowly, "the chef might know. Wait, I'll call him."

As Allison disappeared in the direction of what was evidently the kitchen, we stood outside by the door, waiting.

Kennedy's eye traveled back and forth about us and finally fell on a row of rubbish barrels a few feet away. He moved over to them.

He had half turned away, retracing his steps back to me thoughtfully, when his eye must have been attracted by something gleaming. He turned back and poked at it with his stick. Peeping from the rubbish was a dented thermos bottle, the lining of which was cracked and broken.

He was about to turn away again when his eye fell on something else. It was the top of the bottle, the little metal cap that screws over it, or rather it was what was left of the cap.
