Myron and his wealthy, ruthless best friend Win begin to investigate. They uncover a pattern: someone is framing innocent people for murders, a killer they call the Setup Serial Killer. The trail leads to a series of cold cases, a mob kingpin, and a family hiding dangerous secrets. As Myron gets closer to the truth, he becomes the killer’s final target. In a violent climax in Central Park, the shocking identity of the Setup Serial Killer is revealed, and Myron’s own family ties are tested to the breaking point.

Full Summary

Think Twice opens with a chilling prologue: an unnamed killer describes how to destroy a life by framing an innocent man. After six weeks of surveillance, the killer drugs a target, uses his thumbprint to open a biometric gun case, collects his DNA, and drives the target’s car to a rental where he shoots a woman. He then returns the car, replaces the phone, and hides the murder weapon. The planted evidence points to the innocent man. The killer reflects on the thrill of the setup.

Part One: The Revelation

Two FBI agents — Special Agent Monica Hawes and a younger agent — visit Myron Bolitar at his new office. They claim his former client Greg Downing, believed dead for three years, is alive and his DNA was found at the Callister murder scene. Win, Myron’s best friend, refuses to cooperate and leaves. Myron invokes attorney-client privilege and demands the agents leave. He is stunned. Greg may have faked his death and is now linked to a double homicide.

Myron confronts Win, who hints that Greg planned his disappearance. Win reveals Greg opened offshore accounts and instructed him not to tell Myron. Because Greg never fired MB Reps, Myron insists they must help him even if he is a murderer. Win warns about old emotional wounds but agrees. Myron visits his ex-girlfriend Emily Downing, who tells him about a secret Instagram account Greg used to contact a male fitness model named Bo Storm. Emily suspects Greg faked his death to run away with Bo. She also reveals that Greg knew murder victim Cecelia Callister. The chapter explores Myron’s unresolved feelings for Emily and the secret that Myron is the biological father of Emily’s son Jeremy.

Part Two: The Investigation

Myron and Win fly to Las Vegas. Win plays golf while Myron visits Donna Kravat, whose son Jordan was murdered. Donna’s gay strip club Man United was taken over by the Turant mob. She believes Bo Storm killed Jordan with help from Greg. Donna reveals Bo’s real name is Brian Connors, from Oklahoma, with mother Grace. Myron senses a connection between Bo and Greg.

Myron is abducted by mob thugs working for Joey “the Toe” Turant. They tie Myron to a chair and prepare to cut off his pinky toe. As the shears open, Myron hears a prearranged signal song from a passing car: “The Heart of Rock and Roll.” Win bursts in and kills two thugs. Myron is rescued.

Myron confronts Donna, who admits she tipped off Joey’s men but doesn’t believe Joey killed her son. She argues the evidence was too perfect. Meanwhile, Win visits Joey in prison. Joey deduces that the same person framed both him and Greg Downing using DNA evidence.

Myron and Win learn that Bo Storm is connected to his brother Spark, a former assistant coach under Greg. They trick Spark into meeting them. Win snatches Spark’s phone and finds a call to a Montana area code. Myron flies to Montana and finds Bo Storm disguised as a bartender. Bo explains that Greg was messaging Bo’s mother, Grace, not Bo. They fell in love after Greg learned he had terminal cancer. They ran away together to fake Greg’s death. Bo denies killing Jordan.

Myron tracks down Grace Konners in rural New York. He confronts her about Greg’s supposed death. Greg himself appears alive behind Myron. Greg admits he faked his death because he was burned out from basketball and in love with Grace. They went to Vegas to help Grace’s son Bo, who was being abused by boyfriend Jordan. Bo turned state’s evidence; mobster Joey the Toe killed Jordan by accident. Bo entered witness protection; Greg and Grace then faked their deaths. Myron reveals Greg’s DNA was found under Cecelia Callister’s fingernails. Greg denies involvement. FBI agents surround the house.

Greg is arrested. The FBI suspects him of multiple murders. Myron learns that the FBI is investigating a serial killer who frames innocent people — a pattern Greg may be another victim of. Win refuses to help Greg because Greg rejects their aid. Myron’s biological son Jeremy visits Greg in prison. Greg insists his DNA was planted after a pickup basketball game.

Part Three: The Patterns

Myron and Win meet their former FBI handler PT. PT reveals that a series of solved murders — Jordan Kravat, the Callister double homicide — may be the work of a single serial killer who frames innocent people. The only link between the cases is Greg Downing. PT warns that Greg could be either the killer or another victim.

Myron learns about the murders of Tracy Keating, Walter Stone, and Philip Barry — all with too-convenient evidence. Myron realizes no clear link connects the cases beyond Greg. He drives to Philadelphia to investigate the murder of Ronald Prine. The evidence against Jacqueline Newton is similarly damning. Myron joins Jackie’s defense team. He deduces the killer returned the murder rifle after the killing, narrowing the timeline.

Sadie Fisher, Greg’s lawyer, holds a press conference revealing the existence of a Setup Serial Killer. She names Joseph Turant, Dan Barry, Robert Lestrano, and Greg Downing as wrongfully convicted. The FBI is forced to investigate.

Part Four: The Killer Emerges

The killer — revealed to be Grace Konners — stalks Myron. She admits to herself that she enjoys killing and craves the god-like rush. She decides to kill Myron. She lies in wait near the Imagine mosaic in Central Park.

Myron learns that a burner phone used to threaten the Prine Organization has been traced to the park. He receives a photo of the person who rented a car in Pennsylvania — it is Grace Konners. As he examines the photo, Grace attacks him from behind. Myron deflects the gun but is shot in the neck. Bleeding, he crawls. Grace fires again, hitting him in the back. Myron collapses under a bench.

Jeremy, Myron’s son, rushes in and slaps the gun away, but the bullet hits his hand. Grace re-aims at Jeremy. Greg Downing appears and shoots Grace twice, killing her. Myron slips into unconsciousness.

Part Five: The Aftermath

Six weeks later, Myron waits in a Marrakech hotel room for Greg. Greg confesses to a killing partnership with Grace. They killed together, starting with Jordan Kravat. Greg killed Cecelia Callister and her son Clay when the plan went wrong. Grace tried to frame Jeremy, but Greg killed her to protect his son. Greg claims his killing nature died with Grace. He then jumps through a window to his death.

Three days later, Myron, Win, and Terese fly to Boca Raton. Myron’s family gathers — parents Al and Ellen, and a surprise appearance by Jeremy. The family embraces, crying. Win, usually stoic, wipes away tears.

The book ends with Myron rejecting Win’s claim that the story is over. Myron knows the wounds are still fresh.
