I’ve been following Matt Coyle’s series of hard-boiled mysteries starring Rick Cahill for some time. I like the books quite a lot, but Doomed Legacy proved to be about as dark as its title.

Rick, when he was first introduced, was a loner private eye in San Diego, a disgraced cop who kept office hours in a booth in the steak house where he moonlighted as host. Through his subsequent adventures we’ve seen him reintegrate into human society. Now he’s married and the father of an 18-month-old daughter, the light of his life. At his wife’s request, he’s changed his business model from crime investigation to safe, routine background checks for various businesses.

She knows that he suffers from CTI, “the football player’s disease.” Brain damage from getting hit over the head too many times. What he hasn’t told her is that it’s progressing. He suffers from headaches and memory loss, but the worst of it is the rage attacks. He’s afraid he might endanger the people he loves.

One morning he argues with his wife, which makes him short-tempered when he meets with Sara Bhandari, his contact with Fulcrum Security, of his biggest client. She wants to meet somewhere out of the way, where her colleagues won’t see her. She tells him she’s concerned about some of the people whose security checks have been passed by a new investigative company they’ve hired recently. She thinks the people should never have been cleared, and thinks the investigators are up to something. Rick agrees to look into it as a favor, but he’s in a bad mood and leaves rudely. Something he regrets.

He regrets it even more three days later when, having been unable to reach Sara, he goes to her house and finds her dead – raped and murdered. The police identify the m. o. of a serial rapist in the area, and blame it on him. But Rick isn’t so sure.

Then Sara’s sister hires him to investigate the death. But she fires him abruptly when bad reports (false ones) start spreading about Rick’s own security work. That won’t stop him, of course. It’s personal now. But he has no idea how powerful the people he’s challenging are. And he has no idea the effect it all may have on his family.

I liked Doomed Legacy. It read well except for a couple typos. The occasional references to Christianity and prayer were positive.

But it’s a dark story. I hope the next one proves happier for Rick.
