Long Shadows (amos Decker, #7)

The seventh installment in David Baldacci's Memory Man series opens with FBI consultant Amos Decker woken by a phone call from his former police partner, Mary Lancaster, who has early onset dementia. Lancaster, alone in her Ohio home after sending her aide away at gunpoint, tells Decker she forgot her own daughter Sandy existed that day. Despite his desperate attempts to talk her down, Lancaster shoots herself while he listens. Decker, who once nearly took his own life after the murders of his wife Cassie and daughter Molly, is devastated. He attends the funeral, where Sandy, Lancaster's teenager who has a learning disability, asks where her mother went. Decker cannot bring himself to answer.

Back in Washington, DC, Decker receives a troubling letter from the Cognitive Institute, where he undergoes annual testing for the brain injury he sustained playing professional football. The injury gave him hyperthymesia, a condition allowing near-perfect recall, and synesthesia, which causes him to perceive death as bursts of electric blue light. The letter reports new lesions and anomalies in his brain. He tears it up. His superior, Special Agent in Charge John Talbott, assigns him a new partner: Special Agent Frederica "Freddie" White, a sharp Black woman from Baltimore with two children and her own devastating loss. Her son Donte was killed by a stray bullet from gang violence five years earlier. Talbott sends them to Florida, where a federal judge and her bodyguard have been found dead.

In the gated community of Ocean View near Naples, Decker and White join the investigation alongside local FBI agent Doug Andrews. Judge Julia Cummins lies stabbed 10 times in her bedroom, a blindfold fashioned from her handkerchief placed over her eyes with holes cut out, and a card bearing the Latin legal phrase "res ipsa loquitor," meaning "the thing speaks for itself," resting on her body. Her bodyguard, Alan Draymont, a private operative from Gamma Protection Services, is shot twice in the chest in the downstairs study. There is no forced entry. The medical examiner later reveals that old Slovakian banknotes, currency defunct since 2008, were stuffed into Draymont's throat after death.

Decker and White interview the judge's neighbor Doris Kline, who found the body, and learn about the judge's ex-husband, Barry Davidson, and their 17-year-old son Tyler, a nationally ranked football player. Tyler provides his father's alibi: He heard Davidson conducting international Zoom calls from before midnight until nearly 3 a.m. A downstairs neighbor later corroborates hearing Davidson working through the night.

The investigation leads to Gamma Protection Services in Miami, run by Kasimira Roe, daughter of the firm's founder, Kanak Roe, a Slovakian immigrant and former Secret Service agent who vanished three years earlier during a solo boat trip. The only employee who can discuss Draymont's assignment, Alice Lancer, collapses before speaking and is removed from the hospital by two men posing as detectives. Cummins's secretary, Patty Kelly, also disappears after receiving a one-word text, "Run," minutes before Lancer walked into the Gamma conference room.

Through meticulous crime scene analysis, Decker determines that Cummins and Draymont were having a sexual relationship rather than a standard protection arrangement. Evidence including two wineglasses, the judge's freshly applied makeup, and disheveled bedding supports this conclusion, and DNA later confirms it. Critically, blood on the staircase belongs to Draymont, not Cummins, meaning the judge came downstairs after the shooting. This leads to Decker's central theory: There were two separate killers. A shooter killed Draymont and left; a second person then attacked the judge with a knife.

White travels to DC and uncovers that Draymont and Lancer ran a blackmail operation during their overlapping time on Capitol Hill, where Draymont served as a Capitol Police officer and Lancer worked as a lobbyist. Kasimira confesses to Decker that Draymont was blackmailing her over a photographed affair, coercing her into overlooking their schemes at Gamma. Decker and White trace Kelly to Key Largo, where she reveals she is Lancer's biological mother. Kelly says Lancer and Draymont discovered something important and were trying to profit from it. As they escort Kelly outside, a sniper kills her and wounds Andrews.

Pursuing the Slovakian currency connection, Decker investigates Kanak Roe's past and traces a pivotal event to November 1981, when President Reagan gave a fundraising speech at the Fontainebleau hotel in Miami for Senate candidate Mason Tanner. A former Secret Service colleague reveals that Roe stayed at the hotel that night and was a changed man by morning. On Sanibel Island, Tanner's daughter, Deidre Fellows, reveals that as a 15-year-old she wandered into her father's hotel suite and saw Roe and another man wrapping the body of a dead young Black woman in sheets. A cold case search identifies the woman as Wanda Monroe, a 23-year-old reported missing the next day and never found.

The breakthrough comes when Decker matches a photo of a young man standing with Tanner to Trevor Perlman, the judge's next-door neighbor. Decker theorizes that Perlman is a deep-cover Russian operative who had Monroe drugged and killed, planted her body in Tanner's bed, then blackmailed the senator throughout his career on the Intelligence Committee. When Kanak Roe, dying of cancer and driven by guilt, told Perlman he intended to confess, Perlman had him killed during his final boat trip. Decades later, Draymont and Lancer found incriminating evidence and tried to blackmail Perlman, who had them killed, using Davidson's stolen gun to frame him and purchasing Slovakian currency under Kasimira's hacked credit card to implicate her and destroy Gamma.

Decker lures Perlman into a full confession using a concealed recording device, and White leads a tactical team that arrests him. Perlman's demand to contact the Russian embassy confirms his identity as a foreign operative.

One murder remains: Julia Cummins. A remark from Tyler's teammate triggers Decker's memory. The teammate mentioned that Tyler stopped running with the team the morning the body was found, before Tyler could have known his mother was dead. Decker also recalls Tyler washing his father's clothes and deliberately spilling a drink to justify running another laundry load, behavior consistent with destroying evidence. Decker determines that Davidson used a pre-recorded voice memo played at high volume to fool the downstairs neighbor into thinking he was home, then rode Tyler's electric bike to Cummins's house. Arriving to find Draymont dead and Julia beside the body, Davidson snaps. He grabs a kitchen knife and kills her, leaving the blindfold and the "res ipsa loquitor" card, the phrase Julia had always used to blame him.

Davidson confesses in exchange for a guarantee that Tyler will not be charged as an accessory. Decker delivers the news to Tyler at the football field, and the devastated teenager hugs him fiercely. Decker tells Tyler the story of Melvin Mars, a man Decker once freed from death row, a football star wrongfully imprisoned for 20 years who rebuilt his life, to show that recovery is possible.

Back in DC, Talbott tries to separate the partners by transferring them to distant offices. Decker threatens to go public with the story of two agents punished for solving a major spy case, and Talbott backs down. White invites Decker to Baltimore to meet her family, and he accepts, telling her his friends call him Amos. In the final scene, Decker sits alone by the Anacostia River, having retrieved and reassembled the torn letter. He reflects on Lancaster, on his family, on White and her children, and on the uncertain future his changing brain holds. He concludes that life requires spending time living it, and watches the river flow by.
