Soft Touch, by John D. MacDonald (1959)Read about another entry on the list.
John D. MacDonald actually wrote at least two novels that are what I’d call “adultery thrillers,” books that are entirely focused on marriages destroyed by lies. But Soft Touch, one of MacDonald’s finest noirs, is a fast-paced crime thriller in which two old friends try to pull off a heist while embroiled in a love triangle. It’s dark and merciless and shows how easily a marriage (and several lives) can be destroyed by lust and greed.
