Murder at Lilac Cottage

Murder at Lilac Cottage is a 1940 detective novel by John Rhode, the pen name of the British writer Cecil Street. It is the thirty third in his long-running series of novels featuring Lancelot Priestley, a Golden Age armchair detective. In the Times Literary Supplement  reviewer Maurice Willson Disher noted "With both ingenuity and originality at command, he will keep puzzle-solvers guessing until it pleases Dr. Priestley to explain why clues are not what they seem." while Ralph Partridge gave it a broadly positive review in the New Statesman.

Synopsis
In a largely peaceful village in England during the early stages of the Second World War the body of the young man who owns Lilac Cottage is found dead. The only clue that the investigating officers of Scotland Yard can find is a five pound note, but it lures Priestley to the trail. A second murder takes place nearby soon afterwards, puzzling to most, but to Priestley it confirms the theory he is already developing.
