Chief Superintendent Adam Dalgliesh investigates the death of Alice Liddell who ran a home for unwed mothers. One of those residents is Sally Jupp who was a witness in a drugs smuggling and murder investigation in London. Sally works at the local manor house for the Maxies and it is apparent that eldest son Stephen has more than just a passing interest in her. The night after they announce their engagement, Sally is found strangled in her bed. The question is whether her death is related to the London investigation or a completely different reason altogether. Her engagement created a good deal of ill feeling among the Maxies and several guests in the house with any one of them having a motive to kill her.
