The Monogram Murders is a work of detective fiction by Sophie Hannah and first published in the UK by HarperCollins in September 2014. It is the first official novel authorised by the Christie estate to feature Christie's detective Hercule Poirot, and his first literary appearance in 38 years.
Three corpses are discovered in different rooms of the same London hotel, each with a monogrammed cufflink placed in their mouths. The murders take place in 1929, although the motive proceeds from events some 16 years earlier.
