Exit Harlequin by Jessica Ryan. Hardcover first US edition published by Doubleday for The Crime Club 1947. Fair condition copy. Jacket appears to be pasted to boards and is half delaminated or possibly taped along spine. Considerable wear to jacket edges and some light pencilling on the reverse, stamps inside front and rear boards, old penned price inside cover. That said the binding it’s tightly bound and clean, with the jacket art on spine and cover remaining mostly clean and looking really striking. A very scarce title! Very few on the market at all.
