An exclusive authorized edition from the Queen of Myster featuring short stories starring Agatha Christie's most enigmatic sleuth, Harley Quin. Now with a beautiful new series look! It had been a typical New Year's Eve party. But as midnight approaches, Mr. Satterthwaite--a keen observer of human nature--senses that the real drama of the evening is yet to unfold. And so it proves when a mysterious stranger knocks on the door. Who is this Mr. Quin? Mr. Sattherthwaite's new friend is an enigma.

He seems to appear and disappear almost like a trick of the light. In fact, the only consistent thing about him is that his presence is always an omen--sometimes good, but sometimes deadly.
