Sherlock: A Study in Pink

The BBC has created a "series" which consists of mini-movies, basically (90 mins long) Sherlock is set in modern-day London. (he is obssessed with texting)

The first show was loosely based on "A Study in Scarlet", the first Sherlock Holmes story, which was a short novel. The adaptation completely changed the back-story of the crime, but kept some of the essential elements: two pills, one that is harmless, and one that will kill. Also, the (last) victim wrote "RACHE" (although in the novel it is the criminal who wrote this) Holmes thinks it's an attempt at Rachel, which is in the novel. But in the novel it turns out it really is "RACHE" (German for revenge) Here, it is Rachel, and it is the password to her phone. The adaptation is much darker, as the victims are completely innocent. In Study in Scarlet, we feel the victims were anything but innocent. Much of the TV show is spent developing the characters of Holmes and Watson. One of the police force tells Watson that Holmes is a psychopath. I'm not sure Doyle ever intended to paint him in such a terrible light, but he certainly is quirky.

Doyle never implied that Watson's war injury is only in his head. But the TV show has him completely drop his cane when he really does need to run, and he never even realizes it is gone.
