"Occasionally, monsieur."

He looked under the cot.

"Then you must have the rest of the bed; where is it?"

His quick eye had discovered the inconsistency of the mattress,—as, indeed, Massard himself had already done,—and his fertile brain jumped at once from cause to effect.

"Probably to wrap the body in. Where's the sink?"

In the little antechamber, redolent with the peculiar and indescribable odor of human flesh and its preservatives, was a long ice-chest, a big iron sink, an old-fashioned range, pots, pans, shelves with bottles, etc.

Massard hurriedly opened the chest, as if half expecting to see a human body there.
