For young detective Aggie Morton and her friend Hector, an opportunity to dig up fossils becomes even more thrilling when a corpse washes ashore in this fourth book in the Aggie Morton, Mystery Queen series, inspired by the life of Agatha Christie as a child and her most popular creation, Hercule Poirot. For fans of Enola Holmes.

After an invigorating but not exactly restful trip to a Yorkshire spa during which she survived a near brush with death and foiled a murderer, aspiring writer Aggie Morton and her friend Hector are thrilled to have the opportunity to stay at a camp by the sea and watch real paleontologists at work. The famed husband and wife team of the Blenningham-Crewes are about to become even more famous with the recovery of the fossilized bones of an ichthyosaur from the sea by Lyme Regis. This news has already caught the attention of an American millionaire, a British museum and a travelling circus owner, who each want the bones for their own collections. Tensions are running high throughout the camp, from the cook, to the collectors, to the Blenningham-Crewes themselves, and become downright dangerous after Aggie and Hector make a discovery of their own: a body on the beach. Not a fossil, but a human body. 

Series Overview: A twisting, charming middle-grade mystery series set in 1903 coastal England inspired by the imagined life of Agatha Christie as a child and her most popular creation, Hercule Poirot.

AGATHA CHRISTIE: The inspiration for Aggie Morton is the world’s bestselling author (after Shakespeare).

FOURTH, AND LAST, IN THE SERIES: The first Aggie Morton, Mystery Queen book earned accolades from Gregory Maguire, Kristin Cashore, Rebecca Stead, Shelf Awareness, Publishers Weekly and Horn Book Magazine, among others.

JLG LOVE FOR PREVIOUS TWO BOOKS: The first two books in this series have both been given the JLG Gold Standard stamp of approval.

STRONG FEMALE CHARACTER: Aggie is smart, shy and considered a little “weird” by the other girls she knows, but she’s never ashamed to be herself.

AWARD-WINNING AUTHOR: Marthe Jocelyn has won many awards for her books, including the The Vicky Metcalf Award for Literature for Young People, for her body of work.

SUPERB CAST OF CHARACTERS: A large, diverse cast of unforgettable characters, some inspired by characters in Christie’s books, will have readers picking favorites.

PITCH-PERFECT ILLUSTRATIONS: Includes a portrait gallery and chapter spots, all beautifully illustrated by Isabelle Follath.

INTERESTING HISTORY: Readers will be transported back in time to 1903 with historical details that inform the story but never intrude.
