Well, maybe not. The setup is familiar, but the way it plays out isn't. Sure, Raven gets involved with the woman. Sure, she tells him lies. Sure, he turns up things that he didn't expect to find. But the way this one plays out isn't the usual way at all.
Benson writes well, and he's in control all the way here, right up to the starkly noir (and maybe a bit sentimental) ending. This is prime stuff.
The edition I have is apparently a bit pricey, but the book was reprinted as Cain's Wife (more PC?), and copies of that one are dirt cheap if you want to take a chance and read it.
