The Blackhouse is the first novel of The Lewis Trilogy by Scottish writer Peter May. A suspense thriller, the action takes place mostly on the remote and weather-beaten Isle of Lewis off the coast of northern Scotland. The protagonist, Detective Inspector Finlay Macleod (known as Fin), a native of the island, is sent from his Edinburgh police station to investigate the murder of a man who, it transpires, was the bully at Fin’s school. The modus operandi of the crime resembles a murder that Fin recently investigated in Edinburgh, so there is the possibility of a common perpetrator.
