Shelley appeared in the TV movie Frederick Forsyth Presents A Casualty of War in 1989. It was the first of a series of feature-length TV movies (called Frederick Forsyth Presents) written by internationally acclaimed author Frederick Forsyth. In it, Shelley played Monica Browne, an enigmatic and very wealthy horse breeder who becomes the love interest of retired British secret service agent Tom Rowse (played by British actor David Threlfall) who was recruited to intercept an arms shipment from Libya to the IRA. The telefilm was shot in England, Germany and Yugoslavia. Shelley said she read Forsyth's books as a young girl and found them to be "very macho, exciting Cold War stuff." Being the only American among the predominantly British cast, she laughed and said, "Yes, I'm the token." She enjoyed working with her British co-stars and found their approach to their craft very interesting.
