"One always embarks on a John Rhode book with a great sense of security. One knows that there will be a sound plot, well-knit process of reasoning, and a solidly satisfying solution with no loose ends or careless errors of fact." - Dorothy Sayers and "The Elm Tree Murder is up to the high standards that John Rhode has set for himself." - Isaac Anderson, The New York Times From the jacket: An expert forger is worrying Scotland Yard, and Inspector Jimmy Waghorn's investigations take him to a high-class residential hotel near London. Under an assumed name Inspector Waghorn mingles with the guests, yet he finds it difficult to believe that the criminal he seeks is among the hotel's very respectable-looking visitors. But the situation soon worsens. In that peaceful atmosphere a murder is committed so baffling and ingenious that even so brilliant an investigator as Dr. Lancelot Priestley is for a time stymied in his efforts to solve it.
