“The writing of this note was identified by Miss Cowper as that of Mr. Prinsep. It is one of the puzzles of this affair.”
“You mean that it would have fitted in better if John Prinsep’s body had been found in the garden,” suggested the superintendent.
“Exactly; as things are it is confusing. About this time Mr. Carter Woodman, Sir Vernon Brooklyn’s lawyer, arrived. At his suggestion we went across to the theatre which overlooks the garden, although the place where the crime was committed and the body found is completely concealed by trees from both the house and the theatre. Our object was to find if any one from the theatre had seen anything of what happened. A caretaker stated that he had seen Mr. Prinsep walking in the garden some time between eleven o’clock last night and a quarter past. I made further inquiries, both in the house and at the theatre; but that, I think, exhausts the discoveries I have made so far.” And the inspector stopped and wiped his face with a green handkerchief.
“You have stated the case very plainly,” said Superintendent Wilson. “Now tell me what you make of it?” And he gave what can best be described as the ghost of a chuckle.
“Ah, that’s just where the troubles come in, sir,” replied the inspector. “I don’t know what to make of it. As I said, it’s as plain as a pikestaff, and yet it can’t be. When I examined Mr. Prinsep’s room I found abundant evidence pointing to the conclusion that he was murdered by Mr. George Brooklyn. But when I go into the garden, I find Mr. George Brooklyn lying dead there, under circumstances which strongly suggest that he was killed by Mr. Prinsep. Yet they can’t possibly have killed each other. It’s simply impossible.”
“You say that there is strong ground for suspecting that Prinsep killed Brooklyn. What is the ground?”
“Well, first there’s that cigar-holder. The second thing is the letter in his writing, though I admit that raises a difficulty. The third thing is that I’m practically certain the finger-prints on the club correspond to those I took from Prinsep’s hands. Then Prinsep was certainly seen walking in the garden.”
“In short, Inspector Blaikie,” said the superintendent, half smiling, “you appear to hold very strong prima facie evidence that each of these two men murdered the other.”
The inspector groaned. “Don’t laugh at me, sir,” he said. “I’m doing my best to puzzle it out. Of course they didn’t kill each other. At least, both of them didn’t. They couldn’t. You know what I mean.”
“You mean, I take it, that they could only have killed each other and left their bodies where they were found, on the assumption that at least one corpse was alive enough to walk about and commit a murder and then quietly replace itself where it had been killed. It will, I fear, be difficult to persuade even a coroner’s jury that such an account of the circumstances is correct.”
