The Cycle of Purges and Suspicion
The Spy Who Came in from the ColdThis thread traces the escalating struggle inside the Abteilung, where fear of betrayal turns interrogation, accusation, and political survival into a repeating cycle.

Agents Disappear

A Pattern of Loss
Repeated removals
Agents under Leamas’s control are killed or arrested with unnerving regularity. The losses begin to suggest that the opposition knows too much about the British network.
Suspicion takes shape
The pattern points toward a leak or a highly placed enemy. Leamas becomes convinced that Mundt is responsible, while the deeper source of the information remains hidden.
Mundt’s Pre-emption

Questions Cut Short
A policy of elimination
Fiedler believes Mundt kills suspected agents before they can be interrogated. He sees the practice as a way to prevent dangerous answers from emerging.
A new target appears
The deaths no longer look like isolated counterintelligence successes. They become part of Fiedler’s theory that Mundt may be hiding his own treachery.
The Report Circulated

Fiedler Makes His Move
A secret report
Fiedler sends his findings to the Praesidium and applies for authority to arrest Mundt. He excludes Mundt from the circulation, hoping to prevent the accused man from destroying the evidence.
A power struggle begins
The report forces senior figures to confront a possible traitor at the heart of their service. Mundt’s allies and opponents now have reason to act before the accusation becomes public.
The Arrest Reverses the Case

Accuser and Witness Seized
A sudden intervention
Men from Berlin arrive, the guards vanish, and Leamas is taken by force. Fiedler is arrested as well, leaving the accusation against Mundt in the hands of his political opponents.
Evidence becomes treason
The same report that was meant to expose Mundt is reframed as proof that Fiedler has joined a British conspiracy. The internal struggle changes direction without resolving the underlying facts.
A Tribunal Without Justice

The Verdict in Practice
Political procedure
The Tribunal is formally an inquiry whose recommendation goes to the Praesidium. Its secret structure gives political leaders room to shape the result without ordinary public safeguards.
Mundt survives
Fiedler is relieved of duty, while Mundt remains positioned to consolidate power. The proceedings settle the immediate conflict by protecting the most useful and dangerous figure.
