Above: the immediately identifiable work of the great Paul Rader fronting Russell Trainer's His Daughter's Friend. This is about a widower who gets into deep, deep trouble with a predatory teen. It came in 1964, after another book along the same lines, Wade Miller's famed Kitten with a Whip. Neither were among the first novels of their type. We'd guess the basic idea of adult-and-teen disaster goes back to the beginning of commercial publishing. The few we've read—aside from Lolita—feature girls above the age of consent back in 1964, and we bet that's the case here too. Those who don't read vintage books might suspect that such behavior is condoned, but it isn't—the entire point of these tales is that the men throw away or almost throw away everything, including their jobs, families, and freedom. We won't know exactly what His Daughter's Friend is about until we buy it, which we'll do, but not at two-hundred-plus dollars. That's the ask at the moment, and it's way too high. But someone will put it online at a reasonable price eventually. They almost always do.
