H.A.R.M. has discovered that American Ambassador to West Germany, Morris Monroe will be vacationing in Morocco. They sent Dmitrij Volkov to assassinate him. UNITY, learning of this plot, sent Bruno Lawrie and Cate Archer to protect the ambassador. This was the first mission in The Operative: No One Lives Forever.
One of the American tourists was Martha, who originally wanted to visit Paris, but her husband Clark insisted that they go to Morocco. It was here that he reveled his true identity to her as a Soviet spy and that he was leaving to return to the U.S.S.R. Distraught, Martha wandered the desert until she was found by Berber nomads near Merzouga. She elected to stay with the desert when Clark asked her to take him back.
