An interesting quick novella of about 100 pages.
Jimmy Perez, detective, receives a request from his ex-wife, Sarah. She asks him to leave his base on Shetland Island, and privately investigate a personal case which is making her distraught.
Sarah has married a doctor in a small village on the mainland of Scotland. A young unmarried school teacher has been found dead, and the local police have concluded she committed suicide. Local gossips
are spreading the word that Sarah's husband was having an affair with the teacher and may have murdered her.
Perez doesn't want to be away from his regular job and daughter for more than two days. He walks around the village questioning various people and neatly solves the case within that time.
