Sophie Hannah is the New York Times-bestselling author of numerous psychological thrillers, which have been published in 49 countries and adapted for television. She also wrote The Monogram Murders, the first Hercule Poirot novel authorized by the estate of Agatha Christie, and its sequels Closed Casket and The Mystery of Three Quarters. Agatha Christie is the most widely published author of all time, outsold only by the Bible and Shakespeare. Her books have sold more than a billion copies in English and another billion in a hundred foreign languages. She died in 1976, after a prolific career spanning six decades.
"Does Sophie Hannah's Poirot live up to our expectations? Yes, he does, and markedly so.... As tricky as anything written by Agatha Christie. The Monogram Murders has a life and freshness of its own. Poirot is still Poirot. Poirot is back."--Alexander McCall Smith, New York Times bestselling author of The No. 1 Ladies' Detective Agency
