“Thistles must be cut down before they flower”

“Thistles must be cut down before they flower” is Mundt’s justification for acting against suspected threats before they can be examined or allowed to develop. Fiedler recalls the phrase while describing Mundt’s shift from helping him capture suspects to killing them, making the metaphor both a statement of policy and a clue in the case against him.

The Maxim and Its Context

Fiedler says that Mundt once described their complementary roles through the image of the interrogator as a painter and the man behind him as a hammer: Fiedler would question suspects, while Mundt would ensure that the investigation served its purpose. What began as a joke, Fiedler explains, became consequential when Mundt started killing suspected agents before they could be questioned. Mundt’s maxim about cutting down thistles before they flower supplies a rationale for that change: a potential danger is treated as sufficient reason for immediate elimination.

Fiedler objects that killing suspects deprives him of the opportunity to question them. His specific concern is Viereck, whom he regards as a promising source of information and whom Mundt took away from him. The maxim therefore marks a practical conflict as well as a moral one: Mundt’s method prevents the investigation from discovering what the suspects might reveal.

From Slogan to Evidence

Fiedler’s account connects the maxim to a broader difference in method. He contrasts Mundt’s shoot-first deterrence with the principle that questions should precede shooting, and suggests that fear of the answers may explain Mundt’s conduct. The phrase is thus not simply a general warning about danger; in Fiedler’s testimony, it is linked to a pattern of killing people before they can speak.

That pattern matters to the evidence about Operation Rolling Stone. During Leamas’s questioning, Peters doubts that Karl Riemeck could have obtained the intelligence attributed to him without help. Leamas later recognizes that Peters shares Control’s earlier suspicion about Riemeck’s access, and considers whether a high-level collaborator is the person Control wants to protect from Mundt. The suspicion that someone in a position of authority is being shielded gives Fiedler’s account of Mundt’s pre-emptive killings a specific investigative context.

The Maxim Reconsidered

Fiedler’s evidence includes the Copenhagen bank account: the co-signatory withdrew the deposited money a week later, on a date coinciding with Mundt’s visit to Denmark under an alias. At the Tribunal, Fiedler sets out the account details and compares Leamas’s later Helsinki deposit with Mundt’s subsequent clandestine journey to Finland. Those correspondences make Fiedler’s suspicion more concrete, while the Tribunal’s proceedings show how the clues are being assembled against Mundt.

The phrase’s significance changes as the case develops. It first explains why Fiedler believes Mundt has obstructed interrogation by killing suspects; later, the money and travel evidence place Mundt within the pattern surrounding Operation Rolling Stone. When Leamas suddenly understands the deception at the heart of the proceedings, the maxim’s logic resonates beyond Mundt’s treatment of suspects: a doctrine that authorizes action before the truth can be heard belongs to a world where inquiry itself may be manipulated.
