The new Hercule Poirot novel - another brilliant murder mystery that can only be solved by the eponymous Belgian detective and his 'little grey cells'. Since the publication of her first book in 1920, Agatha Christie wrote 33 novels, two plays and more than 50 short stories featuring Hercule Poirot. Now, for the first time ever, the guardians of her legacy have approved a brand new novel featuring Dame Agatha's most beloved creation. Hercule Poirot's quiet supper in a London coffee house is interrupted when a young woman confides to him that she is about to be murdered. She is terrified, but begs Poirot not to find and punish her killer. Once she is dead, she insists, justice will have been done. Later that night, Poirot learns that three guests at the fashionable Bloxham Hotel have been murdered, a cufflink placed in each one's mouth. Could there be a connection with the frightened woman? While Poirot struggles to put together the bizarre pieces of the puzzle, the murderer prepares another hotel bedroom for a fourth victim. In the hands of internationally bestselling author Sophie Hannah, Poirot plunges into a mystery set in 1920s London - a diabolically clever puzzle that can only be solved by the talented Belgian detective and his 'little grey cells'.
