“What I intend to say to you will come as a shock . . .” With these words, Lady Athelinda Playford—one of the world’s most beloved children’s authors—springs a surprise on the lawyer entrusted with her will. As guests arrive for a party at her Irish mansion, Lady Playford has decided to cut off her two children without a penny . . . and leave her vast fortune to someone else: an invalid who has only weeks to live. Among Lady Playford’s visitors are two strangers: the famous Belgian detective Hercule Poirot and Inspector Edward Catchpool of Scotland Yard. Neither knows why he has been invited—until Poirot begins to wonder if Lady Playford expects a murder. But why does she seem so determined to provoke a killer? And why—when the crime is committed, despite Poirot’s best efforts to stop it—does the identity of the victim make no sense at all? Addictive, ferociously clever, and packed with clues, wit, and murder, Closed Casket is a triumph from an author whose work is “as tricky as anything written by Agatha Christie” (Alexander McCall Smith, New York Times Book Review, on The Monogram Murders) “Perfect...a pure treat.” - Tana French “Terrific.... uncanny. As Hercule Poirot himself would say, ‘Bravo, Madame Hannah. Bravo.’ ” - Boston Globe “Sophie Hannah’s idea for a plot line was so compelling and her passion for my grandmother’s work so strong, that we felt that the time was right for a new Christie to be written.” - Air Safety Week “ Classic Christie . . . Captures the essence of the originals without being a slavish imitation . . . Clues emerge, but the case remains perplexing. Christie aficionados will delight in the familiar repartee and the intricate deduction of the solution .” - Washington Post “Equal parts charming and ingenious, dark and quirky and utterly engaging…I was thrilled to see Poirot in such very, very good hands. Reading The Monogram Murders was like returning to a favorite room of a long-lost home.” - Gillian Flynn, #1 New York Times bestselling author of Gone Girl “Perfect...a pure treat for Agatha Christie fans.” - Tana French, New York Times betselling author of The Secret Place “Sophie Hannah’s The Monogram Murders does Christie proud. Our favorite detective is back and in impeccable form!” - Charles Todd, New York Times bestselling author of An Unwilling Accomplice “Sophie Hannah is a prodigious talent. I can’t wait to see what she does next.” - Laura Lippman “We Agatha Christie fans read her stories--and particularly her Poirot novels--because the mysteries are invariably equal parts charming and ingenious, dark and quirky and utterly engaging. Sophie Hannah had a massive challenge in reviving the beloved Poirot, and she met it with heart and no small amount of little grey cells. I was thrilled to see the Belgian detective in such very, very good hands. Reading The Monogram Murders was like returning to a favorite room of a long-lost home.” - Gillian Flynn “Sophie Hannah does an egoless, silky job of reviving Agatha Christie?s beloved Belgian detective Hercule Poirot . . . enough so to hope that Hannah turns to Miss Marple next.” - USA Today  “What I intend to say to you will come as a shock . . .” With these words, Lady Athelinda Playford—one of the world’s most beloved children’s authors—springs a surprise on the lawyer entrusted with her will.
