The Target Identified

Naming the Enemy
A dangerous adversary
Control describes Hans-Dieter Mundt as a ruthless and effective operator whose activity has helped destroy the Berlin network. The case against him is rooted in both professional failure and personal hostility.
A selective explanation
Leamas is told that the goal is to discredit or eliminate Mundt. Control does not explain why the Service has a deeper interest in preserving him, making the briefing a carefully limited account.
Fiedler’s Hatred

Choosing the Investigator
A useful rival
Control identifies Fiedler as a capable counterintelligence officer who resents Mundt and may act against him. His opposition offers the British plan a plausible route into the Abteilung’s internal politics.
A built-in danger
The plan depends on Fiedler’s judgment, not on direct British control. If he recognizes the manipulation or loses his position, Leamas’s mission may produce consequences its designers cannot contain.
The Staged Defector

Manufacturing a Traitor
A public decline
Leamas is made to appear impoverished, resentful, and discredited, then attacks a grocer in public and serves a prison sentence. The sequence supplies a believable motive for selling secrets.
A prepared approach
William Ashe and Sam Kiever steer the supposedly ruined agent toward a paid defection. The approach seems opportunistic but follows a design meant to make the enemy believe its own deductions.
The East German Trap

Evidence With a Purpose
Suspicion assembled
Leamas supplies fragments about payments, travel, and restricted files that invite Fiedler to connect Hans-Dieter Mundt to British Intelligence. The facts are arranged to encourage inference rather than deliver a direct accusation.
A dangerous inference
Fiedler’s analytical skill turns the fragments into a case. His conclusion appears self-generated, which is precisely what gives the operation persuasive force and makes its consequences hard to control.
The True Objective

The Mission Reverses
The revelation
Leamas tells Liz that Hans-Dieter Mundt is a British agent and that the operation was designed to preserve him by destroying Fiedler. The apparent campaign against Mundt was a screen for a political rescue.
A compromised victory
London has protected a valuable source by sacrificing an innocent rival and using Leamas and Liz as instruments. The operation succeeds strategically while exposing the moral cost of its success.
