During the time Elspeth Duff, special security advisor for the Kennington hotels, is in forced retirement in Scotland, she discovers an old diary written by her mother in 1943 that gives an account of an unsolved murder that happened on Tay Farm at that time. Dissatisfied with her new life, Elspeth decides to ferret out the murderer despite the long time that has passed since the killing had occurred. She begins by questioning her parents about an escaped prisoner of war, the four Land Girls who worked on the farm and the members of her family who were involved. Her investigation leads to an unexpected conclusion that can only cause pain to people still alive. Should she remain silent or reveal the truth?

Set against the background of the hardships of the Second World War, A Tangle on Loch Tay is rich in details about wartime Scotland and what life was like on the Homefront for the people who lived and worked at Tay Farm, as well as Elspeth’s family history.
