The Pale Horse.

Francis Iles (Anthony Berkeley Cox) praised The Pale Horse in the December 8, 1961 issue of The Guardian: "Mrs Agatha Christie is our nearest approach to perpetual motion. And not only does she never stop, but she drops the ball into the cup nearly every time; and if one is sometimes reminded of those automatic machines where one pulls a handle and out pops the finished product, that is a compliment to the automatic machine and not by any means a reflection on Mrs Christie. For the latest tug on the Christie handle produces a product which is not only up to the standard but even above it. The Pale Horse is in fact the best sample from this particular factory for some time, and that is saying plenty. The black magic theme is handled in a masterly and sinister fashion, and to give away what lay behind it would be unforgivable. This is a book which nobody (repeat, nobody) should miss." Iles further named the novel as his favorite in the paper's Critic's choice for the end of the year, published one week later, writing that "It has not been an outstanding year for crime fiction, but as usual there have been one or two first-class items. The best puzzle has certainly been Agatha Christie's The Pale Horse."
