A Study in Scarlet

The novel is split into two quite separate halves. The first is titled Being a Reprint from the Reminiscences of John Watson, M.D., Late of the Army Medical Department. This part is told in first person by Holmes' friend Doctor John H. Watson and describes his introduction in 1881 to Sherlock Holmes through a mutual friend and the first mystery in which he followed Holmes' investigations. The mystery revolves around a corpse found at a derelict house in Brixton, England with the word "RACHE" scrawled in blood on the wall beside the body.
