A. A. Milne brings to The Red House Mystery all the suspense of a classic whodunit: an unexpected visitor, a mysterious murder, a secret passageway, a beautiful woman and a suspicious valet. But when a guest at the inn becomes a self appointed ‘Sherlock Holmes’ and acquires his own, personal ‘Dr Watson’, some intriguing evidence comes to light. A classic detective thriller from the bestselling author of Winnie the Pooh.

Written in 1922, before Winnie the Pooh was even born, "The Red House Mystery" was a gift for Milne's father, a retired headmaster who loved mysteries. The book was immediately popular; Alexander Woollcott called it "one of the three best mystery stories of all time."
