512 pages. The head and tail of the spine strip are bumped, the back cover carries a squiggle in blue biro which carefully avoids the print, the pages are tanned, there is a price stamp from a Milanese bookseller and the front hinge is cracked at the tail. Despite this the binding remains solid, solid enough to suggest book is unread. First published in 1947, tenth printing. "In Knock on Any Door, Motley creates a painfully vivid picture of poverty, the struggle for ethnic identity, and the flaws of the penal system in urban America." (goodreads) In 1949 the book was turned into a film directed by Nicholas Ray and starring Humphrey Bogart.
