A Murder of Crows (1999)

Storyline:
In the wake of a career-ending scandal, disgraced lawyer Lawson Russell moves to Key West, where he befriends aging novelist Christopher Marlowe. After letting Russell borrow his latest manuscript, Marlowe dies of a heart attack. When Russell publishes the dead man's manuscript under his own name, he makes the best-seller list—and unwittingly becomes the prime suspect in the investigation of a grisly multiple homicide.
