Colonel Barclay, a commander of the Royal Mallows Regiment, is dead. His wife is the first and main suspect because the servants in the house heard the couple fight and quarrel over something. Some screams followed and shortly after the driver found the commander dead and his wife passed out on the coach. Sherlock Holmes takes up on the case and investigates the crime scene. As always there is much more to the story than it seems in the beginning so he digs deeper in Colonel's past. "The Adventure of the Crooked Man" is a part of "The Memoirs of Sherlock Holmes".
