Mark Ablett is the amiable host of a country-house party to which his estranged brother, Robert, arrives from Australia. Robert is the black sheep of the family who is said to have borrowed money in the past and had written to warn of his visit. One afternoon a gunshot is heard, and Robert is found shot in the head while locked in the library, while his brother Mark has vanished. Tony Gillingham, who has arrived to visit Bill Beverley, one of the guests at the house-party, takes it upon himself to investigate the death. Together Tony and Bill form a Holmes and Watson partnership and seek to solve the mystery in an unorthodox manner, taking over from a bumbling police force.
