Mata Hari Demanded a Million Francs to Spy for France

When French intelligence approached Mata Hari about spying, she named a price: a million francs. The money, according to Britain’s official government-history account, would allow her to stop working and marry her Russian lover, Captain Vladimir de Masloff. A woman already being watched as a possible German agent was negotiating employment with the French.

The dancer’s travels had attracted British attention before the fatal French case. Police detained and searched her in December 1915, finding nothing incriminating. MO5, the organisation that became MI5, subsequently warned ports against letting her return. Her movements, expensive tastes and conflicting explanations of her journeys fed the suspicion.

Ladoux offered her a French intelligence mission. In Madrid she approached Germany’s military attaché, Major Arnold Kalle. Britain’s government-history account describes an effort clumsy enough to alert him—and a British assessment of an ineffective amateur.

Germany had offered its own incentive. The German Spy Museum describes a promise of 20,000 francs for information from elite circles in Paris and her acceptance during financial difficulty. Its historical account questions how much useful intelligence she actually supplied. Recruitment, money and access to well-connected people left a substantial trail of suspicion; the value of the intelligence remains a separate question.

France arrested her on 13 February 1917. A military court conducted the case behind closed doors, and she was executed at Vincennes on 15 October. The museum’s account points to the later release of British intelligence files as an important reason to question the familiar image of an accomplished master spy. Britain’s government historian likewise describes a gulf between the dangerous public reputation and the services’ assessment.
