Nemesis is a 2009 historical mystery crime novel by Lindsey Davis and the 20th book of the Marcus Didius Falco Mysteries series. Set in Latium during AD 77, the novel stars Marcus Didius Falco, informer and imperial agent. In Ancient Greece and Rome, Nemesis was the spirit of divine retribution against those who had succumbed to hubris (overweening pride). In the book, Falco is warned by Anacrites, the Imperial Chief Spy, to be wary of Nemesis following Falco's inheritance of his father's sizeable fortune, while the Claudii, the novel's primary antagonists who meet unpleasant endings, are revealed to have fallen foul of their hubris.
