Sherlock Holmes: A Study in Scarlet #1

Dr. Watson returns from the war in Afghanistan and shares a flat on 221 Baker Street with the consulting detective Sherlock Holmes. Holmes brings Dr. Watson along on a case where an American named Enoch J. Drebber has been killed and the word \"Rache\" (German for \"revenge\") written in blood on the wall. Soon, another American, Joseph Strangerson, is stabbed to death with the same modus operandi. Holmes deducts that the killer is coach driver Jefferson Hope, who blamed Drebber and Strangerson for the death of his girlfriend Lucy. She had been forced to marry Drebber and comitted suicide.
