Such was the problem which my visitor laid before me. It presented, as the astute reader will have already perceived, few difficulties in its solution, for a very limited choice of alternatives must get to the root of the matter. Still, elementary as it was, there were points of interest and novelty about it which may excuse my placing it upon record. I now proceeded, using my familiar method of logical analysis, to narrow down the possible solutions.

“The servants,” I asked; “how many were in the house?”

“To the best of my belief there were only the old butler and his wife. They seemed to live in the simplest fashion.”

“There was no servant, then, in the detached house?”

“None, unless the little man with the beard acted as such. He seemed, however, to be quite a superior person.”

“That seems very suggestive. Had you any indication that food was conveyed from the one house to the other?”
