I’m a softie for compromising photos as a mystery/crime fiction caper staple, enough so that they were the go-to starting point for my own Stiletto Gumshoe’s initial plotting. Just upgrade those B&W glossies to smartphone screens, JPG’s and some frillies that aren’t over fifty years old, and this could still be a sleazy scene from a savvy blackmailer’s or modern-day peeper P.I.’s playbook. But it’s a Robert Bonfils illustration for Don Elliott’s (Robert Silverberg) Passion Pair, a 1964 Leisure Books paperback: “The blackmailers are Jim and Lois MacIntyre, smooth and polished in all the tricks of the trade…and their trade is love…until the pictures are developed. Then the shame and degradation of their victims becomes reflected in a negotiable check…the only true sin money.”
Ahhh, ‘sin money’. It’s what steamy crime fiction dreams are made of.
