Sean Freeman, a central character in Kerry J. Donovan’s police procedural Perfect Record, is a master locksmith, one of the best in spite of his youth. He also has computer skills. So when he arranges to come to the attention of DB Parrish, a London gangster with a weakness for diamonds, Parrish quickly recruits him as his security chief. Sean has personal reasons for needing the kind of money a job with Parrish’s organization will bring in. But he soon learns that working for Parrish means selling your soul. He’ll be required to do things way beyond the limits of his fairly flexible ethics, and the price of failure is a serious beating – if he’s lucky.

So he starts putting out clues for the police, hoping there’s a detective out there smart enough to figure them out. Finally this brings him to DCI David Jones of the Birmingham Serious Crimes Unit. They begin a cautious dance in which jewelry of great value – and innocent lives – are at stake.

I wasn’t entirely happy with Perfect Record, but that was for purely personal reasons. The character of our hero, DCI Jones, is an interesting one (all the characters are good, in fact), but he’s supposed to be an aging curmudgeon and Luddite. The kind of man who won’t have a computer in his home and dislikes the new building he works in out of loyalty to the old one, despite the fact that it’s more comfortable and efficient than its predecessor.

And yet when it comes to Political Correctness, Jones toes the line. He will stand for no sexist language or use of unenlightened titles (like Mrs.) among his officers. If you’re looking for crude cop banter, á la John Sandford, you won’t find it here. I think I can speak with some authority on the subject of curmudgeons as a class, and PC talk is one of the things we tolerate least in real life.

Nevertheless, I have to admit the story is neatly told, with some very nifty (and delightful) surprises at the end. Neat twists generally involve diminished believability in any story, which is the case here. But as pure entertainment, Perfect Record is very close to perfect. The language is relatively mild.
