On a trip into Winchester, former Chief Inspector Angus Sinclair learns of a tragedy that has taken place in the village he is staying in. Beloved church organist Greta Hartmann has slipped and fallen to her death in a shallow creek, and while investigations conclude it to be an accident, her friend and housemate Vera remains unconvinced. After learning that Greta was the widower of a prominent anti-Nazi German preacher, Sinclair meets with the distraught Vera, and he resolves to dig deeper into the story. His investigations lead him to the stately manor of Julia Lesage where she lives with her devoted staff which include her secretary, cook, and driver. Though confined to a wheelchair, Julia is an electrifying spirit with a sharp wit, and those who know her adore her. Among those who do, a gentleman with dubious business dealings is also staying at the house--and Julia appears to be in love with him. A blizzard hits, keeping Sinclair, and later Madden, on the grounds with little to do but analyze the case of Greta's death until a murder takes place, and everyone becomes a suspect.
