But when tourists start turning up dead, he's reluctantly drawn back into detective work-egged on by his barmaid Rosa, a crime drama superfan. With Dennis's real-world experience and Rosa's encyclopaedic TV knowledge, each episode sees the duo tackling a new murder in paradise, whilst trying to remain on the right side of the local Spanish cops.
