While in Paris, Higgins met theatre director Peter Brook and worked with him as playwright-in-residence for his company. They did a play about mountain people in Uganda called "The Ik" which ran in Paris, London and New York. The producers of "The Devil's Daughter" hired Higgins to write a Hitchcock-style thriller. This became "Silver Streak" (1976), which was a hit under the direction of Arthur Hiller. Higgins later said if he had directed it he would have been "a bit less faithful to the writer; I would have slashed away."
