The series follows George and Molly Palmer-Jones, a married pair of amateur sleuths whose shared interest in birdwatching repeatedly draws them into murder investigations. Travelling through varied communities and landscapes, they encounter suspicious deaths, hidden tensions, complicated relationships, and secrets lurking beneath seemingly peaceful surroundings. Combining traditional British mystery with Cleeves’ strong sense of place and interest in the natural world, the series offers atmospheric, character-driven mysteries centred on an engaging husband-and-wife team.
