“It didn’t amount to anything as a clue,” returned Rob moodily. “I showed it to some of the servants, and they said they had never seen such a thing before. Harris was quite sure that none of the men who came here ever use them. I asked Carleton, just casually, for one the other day, and he said he didn’t have any and never had had any. I asked Willard for one at another time, and he said the same thing. It must have been dropped by some of the decorator’s men; they seemed a Frenchy crowd, and I’ve been told the French are addicted to these things.” Rob took the tiny silver sphere from his pocket and looked at it as he talked. “Besides, it wouldn’t mean a thing if it had belonged to anybody. I just picked it up because it was the only thing I could find in the drawing-room that wasn’t too heavy to lift.”
