Again the shadow round this strange man seemed to me to be taking more definite shape. His record must be examined. His rooms must be privately searched. Stackhurst was a willing collaborator, for in his mind also suspicions were forming. We returned from our visit to The Haven with the hope that one free end of this tangled skein was already in our hands.

A week passed. The inquest had thrown no light upon the matter and had been adjourned for further evidence. Stackhurst had made discreet inquiry about his subordinate, and there had been a superficial search of his room, but without result. Personally, I had gone over the whole ground again, both physically and mentally, but with no new conclusions. In all my chronicles the reader will find no case which brought me so completely to the limit of my powers. Even my imagination could conceive no solution to the mystery. And then there came the incident of the dog.

It was my old housekeeper who heard of it first by that strange wireless by which such people collect the news of the countryside.
