A smart and charming middle-grade mystery series starring young detective Aggie Morton and her friend Hector, inspired by the imagined life of Agatha Christie as a child and her most popular creation, Hercule Poirot.

Aggie Morton lives in a small town on the coast of England in 1902. Adventurous and imaginative but deeply shy, Aggie hasn't got much to do since the death of her beloved father . . . until the fateful day when she crosses paths with twelve-year-old Belgian immigrant Hector Perot and discovers a dead body on the floor of the Mermaid Dance Room! As the number of suspects grows and the murder threatens to tear the town apart, Aggie and her new friend will need every tool at their disposal -- including their insatiable curiosity, deductive skills and not a little help from their friends -- to solve the case before Aggie's beloved dance instructor is charged with a crime Aggie is sure she didn't commit.

Kristin Cashore, author of the Graceling series
"Heartfelt, funny and suspenseful, The Body under the Piano is an excellent beginning to what is sure to be a pleasantly gruesome series."
STARRED REVIEW, Shelf Awareness
"Jocelyn offers an enjoyable entrée to the Queen of Crime and to the genre; the narrative’s arch tone, the girl’s vital grandmother, and the novel’s surfeit of extravagant teas should please."
