When a retired cop is murdered on a remote Scottish Isle, DI Alec McKay must dig into the man’s corrupt past in this British crime thriller series.

When he’s found dead, the police assume it’s an accident—until Bridie reveals that he’s been receiving mysterious letters containing only the phrase: “NOT FORGOTTEN. NOT FORGIVEN.”
