Wallis toured China, and while in Beijing stayed with Katherine and Herman Rogers, who were to remain her long-term friends. According to the wife of one of Win's fellow officers, Mrs Milton E. Miles, in Beijing Wallis met Count Galeazzo Ciano, later Mussolini's son-in-law and Foreign Minister, had an affair with him, and became pregnant, leading to a botched abortion that left her infertile. The rumour was later widespread but never substantiated and Ciano's wife, Edda Mussolini, denied it. The existence of an official "China dossier" (detailing the supposed sexual and criminal exploits of Wallis in China) is denied by historians and biographers. Wallis spent over a year in China, during which time—according to the socialite Madame Wellington Koo—she only managed to master one Chinese phrase: "Boy, pass me the champagne". By September 1925, she and her husband were back in the United States, though living apart. Their divorce was finalised on 10 December 1927.
