While in France, Diana edited the fascist cultural magazine "The European" for six years, and to this magazine she herself sometimes contributed material. She provided articles, book reviews, and regular diary entries. Many of her contributions were republished in 2008 in "The Pursuit of Laughter". In 1965, she was commissioned to write the regular column "Letters from Paris" for "Tatler". She specialised in reviewing autobiographical and biographical accounts as well as the occasional novel. Characteristically she would provide commentary of her own experiences with and knowledge of the subject of the book she was reviewing. She wrote regularly for "Books and Bookmen" and her 1980 review of a biography on Magda Goebbels attracted the attention of Christopher Hitchens. Hitchens objected to a passage where Diana wrote: "Everyone knows the tragic end. As the Russians surrounded Berlin, the Goebbels painlessly killed their children and then themselves. The dead children were described by people who saw them as looking 'peacefully asleep'. Those who condemn this appalling, Masada-like deed must consider the alternative facing the distraught Magda." Hitchens insisted that the "New Statesman" issue an editorial condemning the Masada trope. In her eighties she had become the lead reviewer for the "London Evening Standard" during A. N. Wilson's seven-year tenure as literary editor. In 1996, following Wilson's departure, his successor was asked by the new editor of the newspaper, Max Hastings to stop running Diana's reviews. Hastings is alleged to have said that he did not want any more "bloody Lady Hitler" in the newspaper. Diana and the newspaper resumed their relationship following Hastings' retirement in 2001.
