Sherlock Holmes - Deductions

“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.”

“All I heard pointed in the one direction. The amazing strength, the skill in the use of the harpoon, the rum and water, the sealskin tobacco-pouch with the coarse tobacco — all these pointed to a seaman, and one who had been a whaler. I was convinced that the initials ‘P. C.’ upon the pouch were a coincidence, and not those of Peter Carey, since he seldom smoked, and no pipe was found in his cabin. You remember that I asked whether whisky and brandy were in the cabin. You said they were. How many landsmen are there who would drink rum when they could get these other spirits? Yes, I was certain it was a seaman.”

“If it were a seaman, it could only be a seaman who had been with him on the Sea Unicorn. So far as I could learn he had sailed in no other ship.

When I found Patrick Cairns among the harpooners, my research was nearing its end. I argued that the man was probably in London, and that he would desire to leave the country for a time.”
