An account of the libel trial brought against the author and Penguin Books by Holocaust denier David Irving in the year 2000 in London. Relates how Irving's attempts to foil Lipstadt's criticism of his acts of Holocaust denial were frustrated; the trial culminated in Irving's total defeat. Expert historians disproved Irving's claims, e.g. that Hitler was not responsible for the Holocaust and that there were no gas chambers at Auschwitz, highlighting his falsification of history. The trial also substantianted his antisemitism.

This book recounts the libel suit against historian Deborah Lipstadt by David Irving, which resulted in a formal denunciation of a Holocaust denier.

In her acclaimed 1993 book Denying the Holocaust, Deborah Lipstadt called putative WWII historian David Irving "one of the most dangerous spokespersons for Holocaust denial." A prolific author of books on Nazi Germany who has claimed that more people died in Ted Kennedy's car at Chappaquiddick than in the gas chambers at Auschwitz, Irving responded by filing a libel lawsuit in the United Kingdom -- where the burden of proof lies on the defendant, not on the plaintiff. At stake were not only the reputations of two historians but the record of history itself
