(by Leighton and Feynman) and "What Do You Care What Other People Think?" (by Feynman, edited by Leighton). Written after Feynman's death, the book tells the story of their obsession with the town of Tuva in the Soviet Union and their plans to visit which were cut short by Feynman's early death. The story formed the basis of a Channel 4 "Horizon" programme.
