Henry Knox is back, having survived Protegimus.

Trying to step out of the spotlight cast on him after York, Knox takes what should be a routine surveillance job, only to find himself in the wrong place at exactly the wrong time. Two detectives are discovered executed on an industrial estate, drugs planted to tarnish their names, while a covert investigation into the abuse of teenage girls is already being quietly buried.

As the official story closes in and the real killers remain at large, Knox is drawn into a brutal conspiracy of trafficking, corruption, and murder. To uncover the truth, he’ll have to work off the books, trust all the wrong people, and risk becoming the next body left behind.

For readers who like their thrillers tense, emotional, and sharply realistic, Knox Investigations delivers a wounded hero, a ruthless conspiracy, and a case that cuts far closer to home than Knox can afford.
