For Detective Sergeant Fin O'Malley, things are going from bad to worse. His wife and daughter have left him, and his boss is sidelining him. He is tasked with tracking down a suspect who has been dead for ten years in a godforsaken spot somewhere on the northwest coast of Ireland. There are some skeletons in the closet here, and initially, Fin's questions hit a brick wall. This is especially true with Charlotte Quinn, who repairs church frescoes and lives in a lonely lighthouse. In the local pub, Fisherman's Fellow, he gets his first clues and wakes up with a headache the next day. Did the old witch Nora Nichols really want him to believe that Charlotte was a mermaid? Exciting, filled with humor and Irish charm, Carolin Römer tells a story in her crime novel that could only take place in Ireland. Here, former pirates, atheist priests, and undercover agents make an appearance.
