[3] Keeping Mazarine Pingeot's identity from the public was one of the motivations behind some of the illegal wiretapping that Mitterrand ordered under the guise of fighting terrorism.

In 1998, she published her first novel, titled Premier Roman ("First Novel"), which was not highly praised by critics but was translated into many languages, including English.

In 2000, she published Zeyn or the Reconquest, for which Charles Bremner of The Times wrote "If there was a prize for braving the ridicule of critics, it would go to Mazarine Pingeot" (8 May 2000).

In 2007, she published her fifth book, Le Cimetière des poupées (The Cemetery of the Dolls), a novel about a woman who kills her baby and puts it in a freezer.

In 2019, Mitterrand Pingeot published a novel titled Se taire ("Keeping quiet") about a female photographer raped by a prominent politician.
