The Executioner (1970) Timeline Explained – Every Event in Order

Shay kills Booth because he becomes convinced Booth is a Soviet double agent who set him up during the overseas assignment that nearly killed him. Acting on his suspicions without official backing, Shay confronts Booth and kills him, believing this will eliminate an obstacle to uncovering the truth about the mole inside MI5.

Foreshadowing: Shay's near-death experience overseas planted the seed of paranoia that drove his obsessive investigation.

Yes, Booth was indeed a double agent, but the truth is more complicated. Colonel Scott reveals at the end that Booth was actually working for MI5, not the Soviets. He was used by British intelligence to feed false information to the Soviets, making him a double agent in the sense that he was pretending to work for them while actually serving British interests.

Foreshadowing: The formal hearing that cleared Booth of wrongdoing takes on new meaning after the final revelation.

Booth was cleared at the hearing because his actual role as an MI5-controlled double agent was classified at the highest levels. The official hearing had no knowledge that Booth was secretly working for British intelligence, so he appeared innocent. Shay's suspicion was technically correct about Booth's double dealings, but he misunderstood which side Booth was truly serving.

Foreshadowing: The hearing outcome frustrated Shay and fueled his determination to investigate privately.

Sarah helps Shay because she believes he is still her husband Adam Booth. When Shay assumes Booth's identity after killing him, Sarah has no idea her husband is dead. She assists 'Booth' (actually Shay) believing it is her own husband conducting official business, providing him with access and information that aids his investigation.

Foreshadowing: Shay's decision to impersonate Booth directly depends on Sarah's willingness to trust the man she thinks is her husband.

After killing Booth, Shay takes his colleague's identity to continue the investigation from within Booth's network. By impersonating Booth, Shay gains access to restricted information, can move through MI5 circles without raising suspicion, and can meet Booth's contacts to gather evidence about the mole. The identity swap gives him a strategic advantage in tracing Booth's supposed Soviet connections.

Foreshadowing: The plane ticket found in Booth's pocket provides the literal means for Shay to continue Booth's journey.

In Corfu, Shay and Sarah are captured by Soviet agents who hold them hostage. The Soviets want to exchange the captives for Philip Crawford, a British scientist whose information is valuable to the operation. The capture creates a dangerous hostage situation that raises the stakes significantly. They are eventually rescued by Professor Parker, a CIA operative.

Foreshadowing: The trip to Corfu was part of Booth's original mission, which Shay inherited through the impersonation.

Professor Parker is a CIA operative who intervenes to rescue Shay and Sarah from their Soviet captors in Corfu. His intervention frees them from captivity and allows the investigation to continue. His involvement adds an American intelligence dimension to what began as a purely British operation, suggesting the case has international implications.

Foreshadowing: Parker appears precisely when the situation becomes most dire, indicating higher-level intelligence coordination.

Philip Crawford is a British scientist whose information helps guide the operation. The Soviet agents capture Shay and Sarah specifically to exchange them for Crawford, indicating his intelligence value is significant enough to warrant a hostage swap. Crawford operates as a pivotal figure in the background of the investigation, with his safety becoming a bargaining chip.

Foreshadowing: The Soviet desire for Crawford explains why they took such a risky public action in Corfu.

Colonel Scott reveals the full truth about Booth's role: Booth was a double agent used by MI5 to feed false information to the Soviets. This reframes Shay's entire investigation, showing that Booth was not a traitor to Britain but a covert operative serving British interests. The revelation exposes the web of deception that operated even within MI5's own ranks.

Foreshadowing: Colonel Scott's delayed revelation suggests higher-level clearance was required to protect the operation.

Shay was nearly killed during an overseas assignment that he believes was a deliberate setup, not bad luck. He returns to London convinced the near-fatal mission was personal and intentional, which launches his private investigation into finding the mole. The exact source of the setup is never definitively proven within the story, but it fuels his paranoid pursuit of Booth.

Foreshadowing: This early trauma sets the entire plot in motion, as Shay's conviction about being framed drives every subsequent decision.
