Sir Arthur Conan Doyle: The Return of Sherlock Holmes

6. The Adventure of Black Peter. (continued)

Sherlock Holmes's face showed that he was thoroughly taken aback by this new development.

"I must admit both your points," said he. "I confess that this note-book, which did not appear at the inquest, modifies any views which I may have formed. I had come to a theory of the crime in which I can find no place for this. Have you endeavoured to trace any of the securities here mentioned?"

"Inquiries are now being made at the offices, but I fear that the complete register of the stockholders of these South American concerns is in South America, and that some weeks must elapse before we can trace the shares."

Holmes had been examining the cover of the note-book with his magnifying lens.

"Surely there is some discolouration here," said he.

"Yes, sir, it is a blood-stain. I told you that I picked the book off the floor."

"Was the blood-stain above or below?"

"On the side next the boards."

"Which proves, of course, that the book was dropped after the crime was committed."

"Exactly, Mr. Holmes. I appreciated that point, and I conjectured that it was dropped by the murderer in his hurried flight. It lay near the door."

"I suppose that none of these securities have been found among the property of the dead man?"

"No, sir."

"Have you any reason to suspect robbery?"

"No, sir. Nothing seemed to have been touched."

"Dear me, it is certainly a very interesting case. Then there was a knife, was there not?"
