Wolff returned to public life, frequently lecturing on the internal workings of the SS and his relationship with Himmler. This resulted in his appearing in television documentaries including The World At War saying that he witnessed an execution of twenty or thirty partisan prisoners in Minsk in 1941 with Himmler. In the early 1970s, Wolff promoted the theory of an alleged plot to kidnap Pope Pius XII. Most other allegations of such a plot are based on a 1972 document written by Wolff that Avvenire d'Italia published in 1991, and on personal interviews with Wolff before his death in 1984. Wolff maintained that on 13 September 1943, Hitler gave the directive to "occupy Vatican City, secure its files and art treasures, and take the Pope and Curia to the north". Hitler allegedly did not want the Pope to "fall into the hands of the Allies". Wolff's reliability has been questioned by Holocaust historians, such as István Deák, a professor of history at Columbia University. Reviewing A Special Mission by Dan Kurzman, a promoter of the theory, Deák noted Kurzman's "credulity" and that the latter "uncritically accepts the validity of controversial documents and unquestioningly believes in the statements made to him by his principal German interlocutor, the former SS General Karl Wolff". He further criticized the book's "modest documentation" containing "a great number of vague or inaccurate references". In the late 1970s Wolff also became involved with Stern journalist Gerd Heidemann. Together with Heidemann, he travelled through South America, where he helped to locate, among others, Klaus Barbie and Walter Rauff, with whom Heidemann conducted interviews for a series of articles. Wolff served as a consultant for the alleged Hitler Diaries and was upset when they turned out to be forgeries by Konrad Kujau. Asked to attend the trial of Heidemann and Kujau, Wolff declined; on 17 July 1984, he died in a hospital in Rosenheim. He was buried in the cemetery at Prien am Chiemsee on 21 July. A few weeks before his death, Wolff declared the Islamic profession of faith, becoming a Muslim. At his grave, his daughter Fatima Grimm gave the funeral prayer in the presence of representatives of the Islamic Center of Munich (ICM). She was also a Muslim convert, doing so in 1960 while in Munich, later becoming a translator, author and speaker on Islam in Germany.
