"The plotting is ingenious, the pace sustained, the solution satisfying." New York Times Book Review“Amazingly, the story steers along very well despite so many different hands at the tiller. Christie’s solution is typically ingenious.” Mark Campbell, The Pocket Essential Agatha Christie"These members of the Detection Club collaborate with skill in a piece of detection rather more tight-knit than one had a right to expect. There is enough to amuse and to stimulate detection; and the Introduction by Dorothy Sayers and supplements by critics and solvers give an insight into the writers' thoughts and modes of work." Jacques Barzun and Wendell Hertig Taylor, A Catalogue of Crime
