Good characters do a lot to make a book work. But now that I’ve finished You’ll Get Yours, by Gerald Hansen, I think it’s possible to overdo it.

In the city of Derry, Ireland, a middle-aged woman’s body is found, dressed only in sexy underwear, on top of a cannon on the old city wall, her thumb superglued inside her mouth. As Detective Inspector Liam McLaughlin begins investigating, they find the woman hard to identify. No one seems to have known her. And when she finally is identified, as a woman who worked as a stocker at a nearby supermarket, it turns out she’s still a bit of a mystery. She seems to have no family, and there’s no record of her existence prior to four years ago.

In time it’s revealed that she’s been living under a false identity. She was once – briefly – famous, as a member of a Spice Girls-type girl band that had a few hits in the ‘90s. None of the other old group members are living in hiding, though, so what was she afraid of?

And the cops’ work won’t be made any easier by the almost universal hatred for the police that lingers in Derry, a residue from “the Troubles” of the old IRA years. In the end the solution will take them back to an old crime that time can’t bury and no one could possibly guess.

The emphasis in You’ll Get Yours is vivid characterization, and frankly I thought it was a little overdone. DI McLaughlin is a slob who’s always getting interrupted in the middle of eating a sandwich. His subordinates include a feminist detective with OCD, a fashion-plate womanizer, an over-eager rookie detective, and a female computer nerd. I think I was supposed to be amused by their interactions and frictions, but I found it all a little overdone and unconvincing.

The book wasn’t really that bad, plot-wise, and the solution was horrific and moving. But I couldn’t help being annoying by the comic book characterizations.

I should note, however, that references to religion were mostly respectful, and the author took trouble to avoid cursing.

You might enjoy it.
