The Mischief Makers; The Golden Creep; End-Game

The Detective Book Club produced volumes of three crime novels from 1942 to 1999. Originally monthly, near the end they dwindled down to just a few per year. Many famous detective and crime novelists had their early works featured in DBC editions. Often, books were published in DBC editions before, or at the same time as they were published in mass market form.
