The imprint signed David Irving, a scholar, for a Joseph Goebbels biography in 1996 but had to drop the book when it was found out that Irving was a Holocaust denier for having links to Institute for Historical Review, "the literary center of the United States Holocaust-denial movement."
In October 1999, St. Martin's Press recalled a Dunne book, Fortunate Son: George W. Bush and the Making of an American President, and destroyed them after various incidents about the author, J. H. Hatfield, surfaced. The incidents were that he had served prison time for a car-bombing attempt on his former boss's life and that he included an anonymous accusation about Bush. A St. Martin's executive editor resigned in protest over the publication. In November, Dunne editors stopped attending St. Martin editorial meetings and started their own.
In June 2016, PublishersLunch announced that Thomas Dunne Books had been downsized to four employees. 
In April 2020, it was announced that St. Martin's Press had eliminated the imprint as part of its "implementing a job reduction action and hiring freeze" during the economic struggles caused by the Coronavirus disease 2019.
