A serial killer cozies up to another murderer who’s been making headlines in this psychological thriller. Former combat medic Max Mason now works as a nurse at the Carlson Brain Injury & Rehabilitation Center in New Hampshire. He’s also a serial killer, or so he confides to comatose patient Lincoln Douglas Raider. Lincoln’s injury was a simple fall while cleaning the gutters at his house. But his identity is a lot more complicated, as many people now believe he’s the media-dubbed “Huntsman” who has killed several women. Aside from the first victim, each woman has vanished, with her heart and an apple later turning up at her front door. Max becomes obsessed with talking to Lincoln about the psychopathic inclinations they presumably share. He likewise befriends Lincoln’s wife, Jolene, who asks Max for help with her recovering husband when he finally awakens. This gives Max the chance to learn all he can about Lincoln and his twisted mentality at the couple’s farm. But notwithstanding his recurrent nightmares of hurting someone, Lincoln doesn’t apparently remember certain events before his coma. Moreover, his love for Jolene and their newborn daughter looks genuine—hardly the behavior of a killer lacking empathy. As the evidence against Lincoln is circumstantial (he has a vague tie to each victim), Max can’t help but entertain the idea that this man isn’t a murderer. Getting closer to Lincoln could get him answers, but it’s sure to be precarious, as this supposed serial killer’s mind may be unraveling.

Sanders shrouds this mystery in ambiguity, a haziness that clears up as the story progresses. Max, for example, who says little about what he’s done as a serial killer, has a specific agenda in getting next to Lincoln. In addition, “The Captive,” an unnamed woman who’s the Huntsman’s seventh and latest victim, provides an intermittent narrative perspective. It’s not easy to sympathize with the cast members, including Max, until their personalities take shape much later in the novel. But the few supporting characters shine—the Martins, Lincoln’s neighbors who believe in the man’s innocence, and Det. Darby Albright, Max’s sister, whose first murder case as a rookie cop was one of the Huntsman’s unfortunate victims. Despite allusions to serial murders and even Max’s efforts to jog Lincoln’s memory of the brutal deaths, Sanders’ novel is only moderately graphic and instead is heavy on suspense. Uncertainty over what Lincoln may or may not have done makes him all the more frightening; readers are either getting a close-up of a psychopath or no clues to who or where the real killer is. The author churns out unforgettable, sometimes scary moments, such as Max literally getting stuck in a muddy cornfield: “I attempt to stand, and my feet sink deeper. Cold spring water pools and trickles down my legs, filling my shoes and adding to my weight. I’m up to my waist in mud and freezing.” The inevitable twists in the latter half, even if largely predictable, deliver a memorable and convincing final act, with an especially strong last scene.

This shrewd exploration of a killer’s mindset will unnerve and enthrall readers.
