A Triangle For Murder
These are the people who formed the triangle:
Howard Van Horn – a young sculptor suffering from strange attacks of amnesia. He goes in desperation to Ellery Queen with a baffling problem.
Diedrich Van Horn – Howard’s millionaire foster father. His money bought him a wife tailor-made to his specifications. He needed Ellery Queen too – but for a more sinister reason.
Sally – The young and beautiful wife. She came from the wrong side of the tracks but moved in the Van Horn mansion with complete assurance.
Ellery Queen finds a pattern of sins that leads irrevocably to murder. His solution is a spectacular one, and provides this book with the best surprise ending of the great detective’s career.
19th novel in the Ellery Queen series.
A film based on the novel was released in 1971 starring Orson Welles but Ellery Queen was replaced with an investigator named Paul Regis.
