Young Tom French is found dead, lying in a marsh on the Norfolk coast, with his head bashed in and his binoculars still around his neck. One of the best birders in England, Tom had put the village of Rushy on the birdwatching map. Everyone liked him. Or did they?

A routine weekend visit by the Gillibry Bird Observatory Trust is made memorable by the owner’s announcement that he is going to sell the island. A sale would mean the end of the Observatory, which for some of the birders makes life worth living. A fire in Charlie Todd’s cottage adds to their distress. And when, next morning, after a fierce storm, they find Charlie dead in a bird hide, their pleasant September weekend assumes a dangerous new face.

Newlyweds Jim and Sarah are welcomed home from their honeymoon to the Scottish island of Kinness with a huge celebration, and the whole island is present to witness the bitter end. But did Jim’s younger sister Mary fall? Or was she pushed? George Palmer-Jones, retired birdwatcher and amateur detective, suspects the latter. But proving it will be difficult – no one wants to upset the balance of the island’s ancient relationships.

The sight is a particularly horrible shock for George Palmer-Jones, ornithologist and amateur detective, as he was an old friend of the victim Eleanor Masefield. George and his wife Molly are staying at Eleanor’s family-run hotel, and whilst George believed Eleanor was a beautiful and charming widow, Molly has other ideas.
