Quick recap
In London, Dr. Watson, an army surgeon invalided home from Afghanistan, shares rooms on Baker Street with Sherlock Holmes, a consulting detective with odd methods. A man is found dead in an empty house in Brixton, the word RACHE written on the wall in blood. When a second body turns up, Holmes deduces his way to the killer, a cab driver. The second part goes back to the American West, among the Mormons of Utah, and shows the revenge behind the crimes. It is the pair's debut, in 1887.
