A Scotland Yard detective probes a string of strange disappearances and paranormal phenomena in this classic British mystery adventure. Insp. John Appleby has his hands full. It begins when his aunt's horse, Daffodil, disappears from her stable in Harrogate. Meanwhile, Appleby's colleague, Superintendent Hudspith, is searching for a missing young woman by the name of Lucy Rideout. But the most bizarre case is the vanishing of a supposedly haunted house in Bloomsbury. Working together, the puzzled policemen soon find the cases are connected. But what exactly is going on? The answer to that question lies with a madman in the Amazonian jungle . . . Praise for Michael Innes and Inspector Appleby "Innes is in a class by himself among detective story writers." --The Times Literary Supplement "As farfetched and literary as Sayers." --Cambridge Companion to Crime Fiction "A first-rate piece of work, intelligent, well-written, elaborate and exciting. . . . Highly recommended." --The Spectator on Hamlet, Revenge!
