Some familiar authors, some unfamiliar, some -- Michael Crichton, Donald E. Westlake, Elsie Lee, James Atlee Phillips -- under pseudonyms, some unjustly forgotten.
Eight of the twenty-five books were published by Gold Medal. No surprise there. Two from bottom of the barrel publisher Belmont, which still managed from time to time to publish some good stuff, including the two listed here. I never heard of Straight Arrow; I read the Simon in a Pocket Books reprint. If memory serves, I have only read ten of these books.
A few of these books are readily available; others, alas, not as readily. Any of these twenty-five should be well worth your time.
