Patricia Highsmith underwent psychoanalysis in an effort "to regularize herself sexually" so she could marry Brandel. The analysis was brought to a stop by Highsmith, after which she ended her relationship with him. After ending her engagement to Marc Brandel, she had an affair with psychoanalyst Kathryn Hamill Cohen, the wife of British publisher Dennis Cohen and founder of Cresset Press, which later published "Strangers on a Train". To help pay for the twice-a-week therapy sessions, Highsmith had taken a sales job during Christmas rush season in the toy section of Bloomingdale's department store. Ironically, it was during this attempt to "cure"
Patricia Highsmith that she had tried to abort her by drinking turpentine, although a biography of Highsmith indicates Jay Plangman tried to persuade his wife to have the abortion but she refused. Highsmith never resolved this love–hate relationship, which reportedly haunted her for the rest of her life, and which she fictionalized in "The Terrapin," her short story about a young boy who stabs his mother to death. Highsmith's mother predeceased her by only four years, dying at the age of 95. Highsmith's grandmother taught her to read at an early age, and she made good use of her grandmother's extensive library.
