Marie is first seen standing by a car near a wood. She seems cold and drives off.
The next time we see Marie she is meeting Lord Brett Sinclair (Roger Moore) warning him not to get involved with a dead body that was discovered earlier near where they first saw her.
Marie is in fact planning to assassinate the prime minister. She captures Brett and Danny Wilde (Tony Curtis) where she watches on T.V her plan. Brett breaks free and picks Marie up and locks her in a laundry basket as she screams.
