Frank Brennan–Dagmar Poulsen Affair

Dagmar Poulsen’s affair with Frank Brennan links a private relationship to the rented VW Kombi Van that became part of the investigation into Brennan. Her account supplied a timeline for his use of the vehicle and a dispute over its damaged fender, while leaving uncertain whether the affair had shaped the circumstances of the rental.

The Affair

When Carl Mørck told Rose that Dagmar had had an affair with Frank, he described her as having nearly collapsed when his name was mentioned. Dagmar’s reaction conveyed the force of the disclosure, but the account does not explain what she felt or why the relationship ended. Carl also noted that Frank had other affairs when young, placing Dagmar among the women with whom he had been involved.

The Van and the Break

Dagmar confirmed that Frank used the VW Kombi Van from the spring of 1997. He had rented it rather than borrowed it. She thought her husband might have discovered the affair and consequently been unfriendly toward Frank, prompting the rental, but she was never sure; the subject had not been discussed between them.

Frank returned the van around Christmas that year. Dagmar was furious because its fender was dented, and the two argued. After that quarrel, she and Frank never saw one another again. The damaged fender thus marks the final known episode in their relationship as well as a concrete detail in the history of the van.

Investigative Significance

Dagmar’s testimony connected Frank to the vehicle during the period relevant to the investigation and identified a defect that Carl Mørck and Rose could compare with the van’s condition. Photographs showed a heavily corroded front and a fender lying on the ground; when investigators turned it over, they found a very small dent. That mark offered no decisive identification, since, as the exchange acknowledged, dents were commonplace on Copenhagen fenders.

The affair therefore provides a useful but limited link: it places Frank and the rented van together in 1997, and the quarrel corroborates that Dagmar remembered damage when he returned it. Her uncertainty about her husband’s role, and the ordinary nature of the dent, keep the relationship from resolving the vehicle’s significance on its own.
