ASSOCIATION COPY OF THE FIRST EDITION, PRESENTED TO AGATHA CHRISTIE BY THE AUTHOR: "With many thanks to Miss Agatha Christie, not only for permission to mention her name in the blurb of this book, but even more for the many hours of happiness provided by her many enthralling detective stories. Herbert Metcalfe. 24/8/66." The blurb describes the book as being a "'clean' book. It has a mild romantic interest, but for its main appeal relies, not on an orgy of sex, but simply on a jolly good story, in the best traditions of Agatha Christie, Edgar Wallace, and others."
