[3] Real-life Mata Hari embarks on a fictional adventure in which she becomes a spy and uncovers sensitive military secrets, all in the midst of the outbreak of World War I.

[4][5][6] The core idea, a spy game with Mata Hari at the turn of the last century, was created by Christopher Kellner and Marc Buro.

Buro, a producer at DTP, approached both Barwood and Falstein separately and pitched them a game based on Mata Hari, which after discussing the opportunity, felt was "right up our alley".

In August 2007, Barwood and Falstein attended a series of meetings in Hannover to review and fine-tune the design.

[7] Adventure Archiv thought that the game was short at a play time of ten hours.
