“Exactly! As far as it goes. How would all that bear upon the visits by night to the old crypt? We can’t fit that into our plot.”

“No, sir, and there is something more that I can’t fit in. Why should Sir Robert want to dig up a dead body?”

Holmes sat up abruptly.

“We only found it out yesterday⁠—after I had written to you. Yesterday Sir Robert had gone to London, so Stephens and I went down to the crypt. It was all in order, sir, except that in one corner was a bit of a human body.”

“You informed the police, I suppose?”

Our visitor smiled grimly.
