Overview

This episode chronicles the World War I espionage saga of Mata Hari, the famous exotic dancer who became entangled with both British and French intelligence. After being flagged as a German spy by British officer Stephen Dillon in 1915, she attracted the suspicion of French intelligence chief Georges Ladoux, who recruited her as a supposed French agent while actually attempting to trap her. The episode follows her relationships with various military officers, particularly Russian Captain Vadim Maslov, and her increasingly dangerous position between competing intelligence services.

British Suspicions and Initial Detention

In December 1915, British Secret Service officer Stephen Dillon interrogates Mata Hari when her ship docks in Folkestone. Despite finding no incriminating evidence in her luggage, Dillon becomes suspicious of this multilingual, traveling woman who seems to embody everything he associates with potential spies. Though he releases her to continue to France, he flags her as a security risk and requests she be barred from future entry to the UK, setting in motion a surveillance operation that would follow her for months.

  • Mata Hari detained during ship inspection while traveling from Holland to France
  • Search of luggage finds only dance costumes and jeweled accessories, nothing incriminating
  • Dillon becomes suspicious due to her traveling alone, speaking multiple languages, and appearing 'highly immoral'
  • She's released but flagged as suspect and banned from UK entry; French authorities notified
" She is traveling alone, speaks four languages, and maybe German too, although she hasn't admitted it. Her profession means she travels a lot, and she appears highly immoral. She's just the type of woman who he imagines would be a German spy. "

French Intelligence Takes Notice

By June 1916, as France suffers devastating losses at Verdun, intelligence chief Georges Ladoux faces intense pressure to identify German spies. Initially dismissing British concerns about Mata Hari as prudery, he reconsiders after receiving reports claiming she's pro-German, receives money from the German embassy, and has multiple high-profile lovers including military officers. Ladoux orders round-the-clock surveillance, concerned she might be using her romantic relationships to extract military secrets.

  • Over 80,000 French soldiers killed at Verdun; Germans suspected of having inside intelligence on fort layouts
  • Ladoux pressured to catch German spies after Germans accurately bomb ammunition stores and water supplies at Fort Vaux
  • British intelligence reports claim Mata Hari is pro-German in Netherlands and received money from German embassy
  • Ladoux orders agents Monnier and Tarlet to conduct 24-hour surveillance on Mata Hari
" Stem the tide of information going to the Germans, or we'll lose this war. "
