The Onion Field

No book-club-specific point for this title is documented in the sources consulted, and the identical jacket design across the first five printings means jacket appearance cannot be used as a club tell either. US club copies of Delacorte titles of this period are identified in the usual way — no price at the jacket flap and a blind-stamped square or dot on the rear board, with lighter bulk and lower-grade paper than the trade book.
