Dagmar Lahlum

Dagmar Mohne Hansen Lahlum (10 March 1923, Norway – 28 December 1999) was a member of the Norwegian resistance in Oslo during World War II and was later recruited (unofficially) to work for MI5.

[citation needed] In April 1943, when British double agent Eddie Chapman was drinking with German officers in The Ritz bar at Skillebekk, which was also popular with members of the Norwegian national socialist party, his eye fell on the attractive Dagmar, who – complete with a décolletage and high heels – was smoking Craven A's with an ivory mouthpiece.

Troubled by the fact that she was being labelled a German whore by the locals, Chapman compromised his security during a boating trip on the fjord, when they had shared a bottle of cognac over lunch.

When Chapman returned to England, he used Lahlum's first name, Dagmar, as his security code in all of his radio transmissions as evidence that he was still a free agent.

Her promise to Chapman never to reveal his secret led to her pleading guilty during her treason trial in 1947, and being sentenced to six months in jail.
