Sophie Hannah returns with her third Hercule Poirot novel

Crime writer Sophie Hannah has come out with the third of the continuation novels starring Agatha Christie's iconic character Hercule Poirot.

In "The Mystery of Three Quarters", one of the world's most beloved detectives returns in a stylish, diabolically clever mystery set in 1930s London.

In 2014 and 2016, Hannah published "The Monogram Murders" and "Closed Casket", the first new Poirot mysteries since Christie's death.

Last year, HarperCollins had bagged "The Mystery of Three Quarters" and another Poirot novel by Hannah which will be published in 2020.

"It has been a joy and an honour to work with the Christie family and with HarperCollins on my first Poirot novels. I can't wait to get to work on his next two cases," Hannah had said.

Returning home after lunch one day, Poirot finds an angry woman waiting outside his front door. She demands to know why Poirot has sent her a letter accusing her of the murder of Barnabas Pandy, a man she has neither heard of nor ever met.

Poirot has also never heard of a Barnabas Pandy, and has accused nobody of murder. Shaken, he goes inside, only to find that he has a visitor waiting for him a man who also claims also to have received a letter from Poirot that morning, accusing him of the murder of Barnabas Pandy.

Poirot wonders how many more letters of this sort have been sent in his name. Who sent them, and why? More importantly, who is Barnabas Pandy, is he dead, and, if so, was he murdered? And can Poirot find out the answers without putting more lives in danger?
