[9][10] Magnanti's pseudonym was derived from the 1928 novel Belle de jour by Joseph Kessel and the 1967 film of the same name starring Catherine Deneuve, directed by Luis Buñuel.In 2004 The Sunday Times featured a front-page headline incorrectly identifying Sarah Champion as the author of the blog based on erroneous textual analysis by Donald Foster.[17] Such was the nature of the secret that Magnanti's colleagues did not know until one month before she went public, her publishers had been unaware of her true identity until the previous week and her parents found out on that weekend.[17][18][19] After signing her first book deal and starting writing articles for newspapers, only two other people were aware of her identity, her agent Patrick Walsh and her accountant, who handled the financial transactions via a shell corporation.Her books have been published in the UK, US, Portugal, Spain, Slovenia, France, Netherlands, Sweden, Germany, Italy, Czech Republic, Romania, Russia, and China.It attracted positive reviews, with The Guardian listing it among the best recent crime novels[32] and The Times noting "Magnanti's writing is lively and entertaining.[37] She is also an occasional guest on The Book Show broadcast on Sky Arts[38] and has spoken at a number of venues including The Sunday Times Oxford Literary Festival in conversation with India Knight.Magnanti's PhD thesis, awarded from the University of Sheffield Department of Forensic Pathology, was entitled Macrobioinformatics: the application of informatics methods to records of human remains.[51] She collaborated on several EU project policy documents regarding human developmental risks of environmental exposure to chlorpyrifos,[52] phthalates,[53] and DecaBDE and HBCD.Reviewing for The Observer Catherine Hakim wrote "Magnanti offers a pretty sharp analysis of sexual politics: who fabricates the myths and why, the role of both rightwing and leftwing media in building up moral panics, the vast sums obtained by the pressure groups that profit from them, and, more recently, too, by the pharmaceutical companies that plan to profit from newly invented sexual diseases.[58] In May 2016 Magnanti, alongside Paris Lees, was called to give evidence about sex work conditions in the UK to the Home Affairs Committee investigating prostitution laws in Britain.[25] The resulting recommendations by the committee headed by Keith Vaz, released in July 2016, implemented the pair's suggestions[citation needed] to eliminate criminal records[59] of those arrested for prostitution-related crimes.[citation needed][64] In June 2011, an ex-boyfriend issued a libel writ against The Sunday Times for a claim of defamation caused by his mention in the paper.
