I’ve been going through Jeff Shelby’s “Thread Novels,” starring former cop and current lost kid locater, Joe Tyler. This is the last book published to date, as far as I can tell, so tomorrow I’ll have a review from a different Jeff Shelby series. His books aren’t without their flaws, but I like the writing and the damaged main characters.

In many ways, Thread of Truth is a riff on the same theme as the book I reviewed last night. Again a young man has disappeared, and Joe Tyler is asked to try to find him. Again the lost kid is a recovering drug user, who has been clean for a while, but may have been involved in something else dangerous.

Joe Tyler has given up teaching now, a career he never really liked much. So when Desmond Locker’s parents ask him to find their missing son, he takes the job. The boy’s girlfriend has just given birth to his baby, and he had lots of plans for the future. He had not gone back to drugs, everyone insists. He’d been working hard and saving his money.

But his boss says he hasn’t given him the overtime he’s been talking about. So where did his money come from?

There will be no easy answers, and little good news. Many people are hiding secrets.

These books are pretty low key for their genre, but I like that just fine. I enjoyed Thread of Truth as I have the rest of the series. Recommended, with minor cautions for language.
