Sir Derek O'Callaghan is receiving death threats because of the position he takes as member of the House of Lords. He is taken to a nursing home with pains and dies during an operation - a death that is found to be murder. Alleyn investigates. Was it the nurse O'Callaghan used and rejected (and who was also in the operating room)? The doctor who loves her (and led the surgery)? Those threatening his life?
