Don't Let Go

In the suburban New Jersey town of Westbridge, a woman using the alias Daisy works with Officer Rex Canton to entrap men in drunk-driving arrests during custody disputes. She lures a mark named Dale Miller into drinking heavily at a bar, then gets him behind the wheel so Rex can pull them over. When Rex turns back toward his squad car, Miller shoots him twice in the back of the head. As the gun swings toward her, Daisy realizes that after years in hiding, "they" have found her.

Detective Napoleon "Nap" Dumas, a volatile cop who still lives in his childhood home in Westbridge, narrates the story while internally addressing his dead twin brother, Leo. Fifteen years earlier, Leo and his girlfriend Diana Styles were found dead on railroad tracks during their senior year of high school. The official finding was accidental death. Days later, Nap's girlfriend Maura Wells broke up with him by text and vanished. Nap has spent the years since searching for Maura and refusing to accept the official explanation of Leo's death.

Two Pennsylvania detectives arrive at Nap's door with news that Rex Canton, a former classmate, has been murdered. Fingerprints at the scene belong to Maura. Nap learns of the match because, after Maura disappeared, he broke into her house, took a toothbrush and glass to obtain her prints, and entered them into the Automated Fingerprint Identification System with a request for notification of any future hit. The revelation that Maura is alive and linked to Rex's murder propels Nap to Pennsylvania.

At the murder site and a nearby bar, Nap pieces together the circumstances. A bartender describes a brunette named Daisy who left with an older man, and grainy parking-lot footage confirms the woman is Maura. Further investigation reveals Rex had conducted similar DUI stings multiple times, confirming he was lured to that location deliberately.

Nap's best friend Ellie, who runs a shelter for battered women, discovers a crucial link in the high school yearbook: Leo, Rex, and two other classmates, Hank Stroud and Beth Lashley, all wore a pin representing a secret group called the Conspiracy Club. Maura was also a member. The club had been investigating an old Nike missile control center, a Cold War-era military installation in the woods behind their middle school. Of the six possible members, three are dead, Maura is missing, Hank has a severe mental health condition and has disappeared, and Beth left town after graduation.

Nap brings the yearbook to his mentor, Captain Augie Styles, Diana's father. Augie dismisses the conspiracy theory and tells Nap to investigate alone. The search for Hank reveals that a viral video on a page called "Shame-A-Perv" falsely accuses him of exposing himself near the school. Nap traces the fabricated accusation to Suzanne Hanson, a local mother who wanted Hank removed from the grounds.

Maura's mother, Lynn Wells, contacts Nap through Ellie. Lynn recounts how, on the night Leo and Diana died, Maura called to say she was leaving and warned her mother not to speak to police. Afterward, four men confronted Lynn, and she lost an entire week of memory, believing she was taken and interrogated. Over 15 years, Lynn has seen Maura only six times in brief surprise visits where Maura reveals nothing about her life.

Hank's body is found mutilated and hung from a tree. The staging suggests a connection to the viral video, but Nap suspects a deeper link. Former classmate David Rainiv brings Nap a videotape Hank entrusted to him, with instructions to deliver it if Hank was ever murdered. The tape, filmed one week before Leo and Diana died, shows the Conspiracy Club watching a stealth Black Hawk helicopter land at the old base at night. A flash of bright orange, possibly a person in prisoner-issue garb, is visible before the group flees. Nap makes digital copies and emails one to Augie.

Nap confronts Ellie, who admits she has kept secrets for 15 years. Maura came to Ellie's house at three in the morning on the night of the deaths, frightened and covered in dirt, and made Ellie promise not to tell anyone. Ellie also reveals that Diana had told both her and Maura earlier that day about her plan to break up with Leo.

Nap tracks down Andy Reeves, the former base commander. When shown the helicopter video, Reeves threatens to kill Nap and everyone he loves. At a second confrontation, Reeves confesses the base was a CIA black site, code-named "Purgatory," used to detain and interrogate American citizens suspected of terrorism. He then attacks Nap, knocks him unconscious, and waterboards him, demanding the original tape.

Maura, who has been following Nap, shoots Reeves dead and saves his life. She has spent 15 years on the run under assumed names across the country. She recounts her experience from that night: Alone in the woods, she drunkenly sprinted toward the base fence, triggering spotlights and gunfire. She heard Diana scream Leo's name, followed by more shots and silence. Terrified, she fled to Ellie's house. Nap and Maura reconnect after 15 years apart.

Nap tells Augie what he has learned. Augie confesses that he responded to a disturbance call at the base that night but accepted Reeves's cover story about a guard shooting a deer, never allowing himself to connect the incident to Diana's death. FBI agents also confront Nap, demanding the classified tape, but he slips away when Ellie reports locating Beth Lashley at her parents' farm.

Beth, drunk and armed with a rifle, reveals the full truth. Leo, furious after learning Diana planned to break up with him, rallied the Conspiracy Club to punish her. Hank procured liquid LSD, Beth spiked Diana's soda, and Leo ordered the group to carry her into the woods near the base. When the base's spotlights activated, Diana, in the grip of the drug, ran screaming toward the lights and was shot by a panicked guard. The survivors made a pact of silence.

These revelations lead Nap to a devastating deduction: Augie has been killing the surviving club members responsible for drugging Diana. Nap confirms that Augie fabricated a recent trip, using the time to travel to Pennsylvania in disguise and murder Rex. He waits at Beth's farmhouse, knowing Augie will come for her, the last surviving person responsible for Diana's death.

Augie arrives and confesses. That night, Reeves brought Augie to Diana's body, where Leo was sobbing beside her. After interrogating Leo until he confessed to the LSD prank, Augie shot him, then helped load both bodies onto the railroad tracks. Fifteen years later, when Hank sought refuge at Augie's home after the viral video, Hank broke down and confessed his role. Augie killed him too, staging the body as vigilante justice. Augie killed Rex in Pennsylvania but deliberately spared Maura, knowing she had no part in drugging Diana.

Nap disarms and arrests Augie, choosing prison over allowing him to take his own life. As police lead Augie away, Maura confesses the final piece: She told Leo about Diana's breakup plans, inadvertently triggering his vengeful scheme. Nap tells her it is not her fault. In his final address to Leo, Nap chooses to let go: "I'm going to let you go now and grab on to something more substantial" (347).
