Critical reception
Lucy Mangan, writing for The Guardian, praises Algar's "phenomenal performance" and MacCormicks "magnificent and stylish" direction, and says the only problem the show has is that "it is dealing with events that are stranger than fiction." Sara Wallis from Daily Mirror believes that the miniseries are "not hammer-blow viewing that reconstructs grisly murders" but a more detailed account of the impact of undercover work on Sadie. During the BBC Radio 5 Live program, Algar expressed her opinion of Emilia di Girolamo's work, calling it "something unique" and "one of the most exciting dramas." Sean O'Grady, writing for The Independent, named Deceit "a gripping portrayal of a real-life undercover operation". For her performance, Algar was nominated for Best Actress at the 2022 British Academy Television Awards. References
