London: The Crime Club: 1961. 12.5 x 19 cm. 256pp.
First edition, first printing.
A first edition, first printing, in remarkable internal condition, bright and clean pages with no marks, dots, or ownership signs. Dust wrapper slightly rubbed on top as shown. Otherwise, a very good, tightly bound copy, with publisher's original red cloth and title in black.
Very good copy of Agatha Christie's supernatural mystery. The only novel in Christie's oeuvre credited with having saved at least two lives, as early readers of the book recognised the symptoms of thallium poisoning from Christie's detailed and well-researched description.
