'The House That Jack Built' by Brian Clemens

Mrs. Peel receives a letter from her lawyer informing her that she has inherited a house from her uncle Jack. Despite not being aware that she even had an uncle Jack, Mrs. Peel goes to take a look at her new property. But once inside, she finds herself trapped inside a maze of rooms and moving walls designed to drive her insane. Meanwhile, Steed becomes alerted when he discovers that the key to the house has ruined the negatives of the film he is developing. Mrs. Peel discovers that her ‘uncle’ is in fact a deranged technology businessman who wants revenge for sacking him when she was Mrs. Peel-Knight of Knight Industries. As Steed rushes to the rescue, Mrs. Peel finds her life is about to be cut very short indeed…
