Although Archer Mayor’s latest novel, Bomber’s Moon, is considered part of the Joe Gunther series, Gunther himself plays a comparatively minor role. The serious investigative work is left to two of the Vermont-based cop’s well-regarded acquaintances: private investigator Sally Kravitz and photographer/reporter Rachel Reiling. The crime is most unusual. A thief has been breaking into the homes of people who are away but stealing nothing. Instead, he adds spyware to his victims’ communication devices and then waits to see how he can profit from it. But he is not the first person to pursue such an endeavor in this small Vermont town. Kravitz’s own father followed a similar path back in the day (and perhaps still does). He is well aware of this new interloper into the “family trade” and displays more than a little admiration for his successor’s skills—until the new guy gets murdered. The leads, scant though they are, seem to center on a high-priced private school, and before things resolve, there will be significant financial improprieties, more than a bit of class warfare and an increasing body count. The nicely paced Bomber’s Moon is replete with well-developed characters and relationships, with the unusual bonus of oddly likable villains.
