Mons Lie

Mons Lie (born 18 November 1887, died 1916) was a Norwegian merchant marine officer and businessman. He is primarily known for his involvement in intelligence activities for the British during World War I.

Lie initially worked for the Norwegian America Line. In 1915, he became involved in gathering intelligence for the British Secret Intelligence Service (MI6) while operating under the cover of legitimate business activities in Norway. Norway, though neutral, was strategically important due to its proximity to both Britain and Germany. Lie's work involved collecting information about German U-boat activity, shipping movements, and other matters of military importance. He collaborated with other individuals involved in similar intelligence networks in Scandinavia.

Lie's activities contributed to the Allied war effort by providing valuable information about German naval operations. He died in 1916 under circumstances that remain somewhat unclear, although it is generally believed to be related to his intelligence work. Some accounts suggest his death was caused by illness exacerbated by the stress of his clandestine activities, while others speculate about possible foul play. His legacy is tied to the complex and often dangerous world of wartime espionage in neutral countries.
