Almásy is given clues by a local Bedouin man which help the group to discover the location of the Cave of Swimmers, an ancient site of cave paintings in the Gilf Kebir. The group begin to document their find, during which time Almásy falls in love with Katharine. He writes about her in notes folded into his book, which Katharine discovers when Almásy awkwardly accepts her offer of two watercolours she has painted of the cave imagery, and asks her to paste them into the book.
