I told you that I had proposed to myself one or two hypotheses to account for and explain Jeffrey Blackmore's will, and I may say that the curious misplacement of this photograph fits more than one of them.

I won't say more than that, because I think it would be profitable to you to work at this case independently.

You have all the facts that I have and you shall have a copy of my notes of Marchmont's statement of the case.

With this material you ought to be able to reach some conclusion.

Of course neither of us may be able to make anything of the case--it doesn't look very hopeful at present--but whatever happens, we can compare notes after the event and you will be the richer by so much experience of actual investigation.
