Perry Mason's new client had snow-white hair, and confessed to being a great-grandmother; but she smoked big, black cigars, liked dancing, and got a great kick out of a fast life. She hired the detective to recover her granddaughter's I.O.U.'s before her husband, about to contest a divorce action, could make use of them. Perry Mason met the granddaughter outside the owner's offices on a gambling ship, twelve miles from shore.

This was the first bibliography and guide to the American mass market paperback book, and it remains one of the most definitive. The major index is by author, and lists: author, title, publisher, book number, year of publication, and cover price. The title index lists titles and authors only. The publisher index provides a history of that imprint, with addresses, number ranges, and general physical description of the books issued. This is the place that all study of the American paperback must begin.
