Brophy shot him a compassionate look. He had light-brown eyes that floated like bubbles in a carpenter’s level.

As I’ve mentioned, I’ve been reading a lot of free books lately, e-books I get through online offers. You may also have noticed that I’ve panned a lot of these. It’s the dark side of the self-publishing boom. They’re books written, essentially, by amateurs.

But I’d pre-ordered Jonathan Kellerman’s newest book, Unnatural History, and Kellerman is in no way an amateur. What struck me most as I read was how easy the reading was. I didn’t have to wrestle with the text or try to figure out what the author meant. This was like an easy flight with an experienced pilot. I could just relax and enjoy.

The opening of Unnatural History is standard for the series. Alex Delaware, Los Angeles child psychologist, gets a call from his best friend, the gay shlub-detective Milo Sturgis. Milo is at a murder scene that shows signs of psychological weirdness. Would Alex come and consult?

Alex joins him at the home of the victim, Donny Klement, a young professional photographer who clearly had money but lived in minimalist style. He’s been shot to death in his bed. His distraught assistant (once Alex has helped her calm down) tells them that Donny had recently been working on a project where he photographed homeless people. He took them into his home, dressed them in “aspirational” costumes, and took their pictures. Then he paid them – generously.

Alex and Milo agree that letting the homeless into your home and showing them where you keep large sums of money is rather poor security practice. Clearly, they need to hunt for a murderer among the street people.

Until they learn that Donny happens to be the son of one of the world’s richest men, a notorious recluse who has fathered several children (each with a different wife), provided them with money, and otherwise neglected them. Could one of these half-siblings, who barely knew Donny, have killed him for a bigger piece of the estate?

They’ll need to walk the mean streets and visit the halls of wealth before they can finally unravel the mystery.

I was particularly impressed with the characterization in Unnatural History. Kellerman does characters exceptionally well (and sympathetically). Two of my favorite characters were a gun-loving supermodel and a self-aware, bipolar homeless woman (the best homeless character I’ve ever come across in a book).

I wouldn’t say Unnatural History is better than the general run of Alex Delaware novels. It’s consistent with the usual high standard. It was a little shorter than most of them, which is too bad.

Cautions for disturbing themes and language. Highly recommended anyway.
