Hercule Poirot returns in another brilliant murder mystery that can only be solved by the eponymous Belgian detective and his 'little grey cells'. Following the phenomenal global success of The Monogram Murders, which was published to critical acclaim following a co-ordinated international launch in September 2014, international best-selling crime writer Sophie Hannah has been commissioned by Agatha Christie Limited to pen a second fully-authorised Poirot novel. The new book will be published in 2016, which marks the centenary of the creation of Christie's world-famous detective Hercule Poirot, introduced in her first book The Mysterious Affair at Styles.
