Thus, once more, my reasoning only led me into a blind alley at the end of which was the will, regular and valid and fulfilling all the requirements that the law imposed. Once again I had to confess myself beaten and in full agreement with Mr. Marchmont that "there was no case"; that "there was nothing in dispute." Nevertheless, I carefully fixed in the pocket file that Thorndyke had given me the copy that I had made of his notes, together with the notes on our visit to New Inn, and the few and unsatisfactory conclusions at which I had arrived; and this brought me to the end of my first morning in my new capacity.

"And how," Thorndyke asked as we sat at lunch, "has my learned friend progressed? Does he propose that we advise Mr. Marchmont to enter a caveat?"

"I've read all the documents and boiled all the evidence down to a stiff jelly; and I am in a worse fog than ever."

"There seems to be a slight mixture of metaphors in my learned friend's remarks. But never mind the fog, Jervis. There is a certain virtue in fog. It serves, like a picture frame, to surround the essential with a neutral zone that separates it from the irrelevant."

"That is a very profound observation, Thorndyke," I remarked ironically.

"I was just thinking so myself," he rejoined.

"And if you could contrive to explain what it means—"

"Oh, but that is unreasonable. When one throws off a subtly philosophic obiter dictum one looks to the discerning critic to supply the meaning. By the way, I am going to introduce you to the gentle art of photography this afternoon. I am getting the loan of all the cheques that were drawn by Jeffrey Blackmore during his residence at New Inn—there are only twenty-three of them, all told—and I am going to photograph them."

"I shouldn't have thought the bank people would have let them go out of their possession."

"They are not going to. One of the partners, a Mr. Britton, is bringing them here himself and will be present while the photographs are being taken; so they will not go out of his custody. But, all the same, it is a great concession, and I should not have obtained it but for the fact that I have done a good deal of work for the bank and that Mr. Britton is more or less a personal friend."
