A library setting and a librarian sleuth. What‘s not to like? A lot, sadly. The author can‘t decide what he wants to do with the book — cozy mystery, hardboiled detective novel, police procedural interspersed with soft porn. Ambler, our hero, is not that memorable; his police friend, Cosgrove, is not bright; and the women are stereotypes. The narrator of the audio would be perfect if this were a Sam Spade novel, but it‘s not, so he‘s awkward.
