Characters The Medici Return Steve Berry

Thomas Dewberry: The Entity’s Relentless Assassin

Overview

Thomas Dewberry is a professional killer for the Entity, a shadowy Vatican intelligence network. In The Medici Return, he serves as Cardinal Ascolani's primary instrument of violence, tasked with eliminating the novel's protagonists and silencing political threats. Steve Berry crafts Dewberry as a cold, methodical operative shaped by a traumatic childhood and a complete lack of conscience. His presence raises the stakes for Cotton Malone and Cardinal Richter, turning the hunt for the Pledge of Christ into a deadly game of survival.

Plot Role

Dewberry first appears in Chapter 5, where he drives to Stonehenge to meet his handler Bartolomé. He accepts an assignment to assassinate Cardinal Richter and stage the death as a suicide. This contract sets him on a collision course with Malone. Over the course of the novel, Dewberry commits multiple murders: a jockey during the Palio in Siena, a Swiss Guardsman in Cologne, and an unnamed woman on a train. He also attempts to kill Malone and Richter by causing a car crash. His final mission is to assassinate political figure Eric Casaburi in Florence, which he accomplishes with a suppressed sniper rifle. Immediately after, Cotton Malone tracks him to a hotel room and kills him in a direct confrontation.

Motivations and Traits

Dewberry is driven by a combination of religious devotion and a complete absence of empathy. He places his work in a hierarchy of "God, church, and his work," in that order. His childhood is marked by systematic violentization — a five-stage process that transforms him from abuse victim to remorseless killer. His father, a Welshman, beat him and his brother, eventually killing the brother. After experiencing brutalization, violent coaching (being forced to fight), belligerency, violent performances, and virulency, Dewberry commits to violence as his primary response. He shows no regret for any of his acts; he even regrets not killing his own father before the man died of a heart attack.

Professionally, Dewberry is meticulous and patient. He wears latex gloves to avoid leaving traces, plans escape routes in advance, and uses technologically advanced weapons like a Stealth Recon Scout rifle equipped with a high-pressure sound suppressor. He is unassuming in appearance — a fleshy-faced man with a casual dress style — which allows him to blend into crowds. He views himself as a curious, well-read person who enjoys classic films, yet he admits he possesses “no conscience, few moral values, and little to no emotional structure.”

Chronological Arc

Dewberry's arc moves from anonymous professional killer to a cornered target. His introduction in Chapter 5 establishes his backstory and his willingness to accept a risky contract from Bartolomé. Over the following chapters, he executes a series of assassinations that destabilize the hunt for the Pledge. Cardinal Stamm later reveals that he originally recruited Dewberry for retaliatory strikes in violent political hotspots, but Cardinal Ascolani expanded his role to include framing Richter and killing anyone who threatened Ascolani's bid for the papacy. In the novel's climax, Dewberry becomes the focal point of a manhunt. Malone and Stefano track him using his personal phone. When Dewberry assassinates Casaburi in the Piazza del Duomo, Malone storms the Hotel Duomo, kicks open the door of the fourth-floor room, and shoots Dewberry dead.

Relationships

Dewberry maintains few personal connections. His intermediary is Bartolomé, who passes him assignments from the Entity. Bartolomé later betrays Dewberry when Cardinal Stamm pressures him, providing Dewberry's phone number to the protagonists. Cardinal Stamm originally hired Dewberry for the Entity but designed his use only for retaliation against those who had already attacked the church. Cardinal Ascolani corrupts that original purpose, deploying Dewberry offensively to frame and kill innocents. Dewberry's primary antagonist is Cotton Malone, who survives the car crash and ultimately ends Dewberry's life. Cardinal Richter is his main target, but Dewberry never successfully kills him — he fails both the attempted shooting at the Tuscan villa and the staged suicide plan. Eric Casaburi is his final victim, shot twice in the chest on Ascolani's signal.

Key Decisions and Consequences

Dewberry's decision to accept the contract on Richter sets the entire plot in motion. Had he refused, Ascolani might have needed to find another method to discredit Richter. His decision to keep his personal phone active allows Malone to track him to the Florence hotel, a fatal mistake for a man who prides himself on caution. By killing Casaburi, Dewberry eliminates a key political figure but also brings the full force of the opposition down on himself. His final misstep is failing to anticipate Malone's speed: Malone kicks down the hotel door while Dewberry is still re-positioning after the shots. This leads directly to Dewberry's death and the recovery of the Pledge of Christ.

Theme and Symbol Connections

Dewberry embodies multiple themes in The Medici Return:

  • Power and Corruption: Dewberry is a tool of institutional corruption. The Entity — meant to serve the Vatican — uses a killer for personal gain. Ascolani's corruption of Dewberry's original purpose mirrors the broader decay inside the papacy.
  • Legacy and Bloodline: Though Dewberry has no family legacy, his own violent inheritance from his father shapes him completely. He becomes what he hated most: his father. The cycle of abuse is his private bloodline.
  • Faith Versus Truth: Dewberry holds deep religious convictions, yet his actions contradict every tenet of the faith he claims to serve. He sees no hypocrisy in killing for the church, revealing a dangerous fusion of piety and violence.
  • Deception and Betrayal: Bartolomé betrays Dewberry; Stamm admits he originally hired him; Ascolani uses him as a pawn. Dewberry himself is a living deception — an unassuming man who hides a killer inside.
  • Historical Vengeance: Like the medieval Pazzi Conspiracy mentioned in the novel, Dewberry's work is a form of vengeance. Stamm originally used him for retaliatory strikes, a modern version of Renaissance blood feuds.
  • The Epigraph: The opening Italian phrase "In bocca al lupo" ("Into the wolf's mouth") could apply to Dewberry. He enters the “wolf's mouth” of danger every time he takes a contract, hoping the wolf will die — but in the end, the wolf kills him.

Questions and Answers

1. What childhood trauma shaped Thomas Dewberry?

Dewberry's father, a violent Welshman, beat him and his brother regularly. The father eventually killed Dewberry's brother. At age seventeen, Dewberry beat a local bully to death with a cricket bat and threw the body into a river. He experienced a five-stage process of violentization: brutalization, violent coaching (his father forced him to fight), belligerency, violent performances, and virulency.

2. Why does Dewberry work for the Entity?

Cardinal Stamm originally recruited Dewberry for the Entity to carry out retaliatory strikes against those who had harmed the church in lawless regions. Stamm limited his use to defensive violence. Later, Cardinal Ascolani took control of the Entity and expanded Dewberry's role to include offensive assassinations, framing, and blackmail.

3. What is Dewberry's connection to Cardinal Stamm?

Stamm originally hired Dewberry years ago, believing he could control him and use him only for justified retaliation. Stamm describes Dewberry as having "no morals, deep religious convictions, and unique skills." When Ascolani took over the Entity, he reassigned Dewberry against Stamm's original intent.

4. How does Dewberry die?

After assassinating Eric Casaburi from a hotel room overlooking the Piazza del Duomo in Florence, Dewberry tries to escape. Cotton Malone tracks him using Dewberry's personal phone. Malone kicks open the door of the fourth-floor hotel room, dodges gunfire, and kills Dewberry in a shootout.

5. What role does Dewberry play in the novel's climax?

Dewberry serves as Ascolani's executioner. He eliminates Casaburi, the Medici heir who threatened the Vatican, and nearly kills Cardinal Richter. His death at Malone's hands removes Ascolani's primary weapon and allows the protagonists to corner Ascolani with evidence of his conspiracy.
