A Scotland Yard detective probes a string of strange disappearances and paranormal phenomena in this classic British mystery adventure. <p/> 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. <p/> 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 . . . <p/>Praise for Michael Innes and Inspector Appleby <p/> "Innes is in a class by himself among detective story writers." --The Times Literary Supplement <p/> "As farfetched and literary as Sayers." --Cambridge Companion to Crime Fiction <p/> "A first-rate piece of work, intelligent, well-written, elaborate and exciting. . . . Highly recommended." --The Spectator on Hamlet, Revenge!
