Interesting outing for Johnstone, but one that lacks his bat-shit craziness of most of his horror novels. Our lead Matt, is about to retire from the CIA. Typical of Johnstone's leads, he is a hard man, hates lawyers, journalist and politicians, but has a strong moral compass while leaving a trail of blood. His handler, the head man in the company, has one last mission for him. It seems several of his classmates from '67 (high school) are having a reunion back in Denver and then planning on going camping in a remote part of Idaho.
There are strange rumors about the area. For one, a redneck terrorist group, the Citizens for a White America (CWA) do their training there. Secondly, there appears to be some 'lost tribe' of semihumans, called the 'Unseen' living deep in the woods. People regularly go missing around there and their bodies are never found. Recently, the CIA lost an agent there, as did the FBI. So, the director asks Matt to crash the reunion and go camping with his old classmates; while there, he can try to uncover what the hell is going on deep in the woods...
The first half of Watchers is actually pretty good, even for Johnstone, but more of an action thriller than horror. The second half, however, spirals quickly into ludicrous territory, and not even bat-shit crazy ludicrousness. I will not go into the details to avoid spoilers, but it just got harder and harder to suspend my disbelief until this limped to a conclusion. Pacing errors abound along with several continuity errors made this rough going in parts. Few authors could use a good editor more than Johnstone, but at the rate he cranked out books, this was probably a first draft right to the printing press. 2.5 stars, rounding down.
