A fictional version of young Agatha Christie, a bloodthirsty writer, is in an excellent position to solve a gruesome mystery.It's 1902, and 12-year-old Aggie is a strange child in her largely white, English hometown. She's overwhelmingly shy yet gifted with a cutthroat imagination. Thanks to her "Morbid Preoccupation," Aggie is nearly unfazed when she discovers a corpse at her dancing lesson. But when two of Aggie's favorite people are suspected of the murder, she is determined to learn the truth. With the help of a Belgian refugee boy named Hector Perot, Agatha must find the real killer even if her mother, the constables, and an eager journalist all get in her way. A classic anonymous letter made of letters cut out of newspaper must be a key clue, surely. Fictionalizing both the author Agatha Christie and her famous creation as characters in the same mystery is an infelicitous choice at best. Within the world of the tale, Hector adds little; Aggie is the real detective of the pair. Nonetheless, myriad little touches keep this both exciting and enjoyable. Aggie's grandmother is funny and quite saucy. The girl's grief over her recently dead father manifests genuinely: as sudden flashes of grief, as irritation with his financial mismanagement, and as fond recollections of the delicious cake that had appeared in the wake of his death.The protagonist makes a remarkable, cool, and likable detective despite some literary dead weight.

The world is familiar with renowned author Agatha Christie, Queen of Crime, but how did she come to be such a knowledgeable and prolific mystery writer? In this new series, Jocelyn imagines what Agatha (or Aggie) might have been like as a twelve-year-old: marvelously bright and somewhat sheltered, with an eye for detail and a flair for dramatic descriptions. It doesn't take long for a murder to occur, and when Aggie's dear dance instructor stands accused, the budding writer takes it upon herself to investigate further. Many details are pulled from Christie's actual life, seamlessly woven into this compelling, splendidly surprising murder mystery. Readers already familiar with Christie's works will delight in familiar details and humorous inspiration (sharp-eyed readers will notice classic titles worked into the text), and for Christie novices, the story serves as a wonderful jumping-off point into her intriguing world. Mystery aficionados and Christie fans will delight in the old-fashioned whodunit and hope for more of Aggie's adventures.--Emily Graham Copyright 2020 Booklist

Child sleuths investigate a poisoning in this winning whodunit based on Agatha Christie's childhood. In 1902 Torquay, Aggie Morton, 12, whose father recently died, has what her mother calls a "Morbid Preoccupation." Additionally, the aspiring writer, homeschooled and often shy, likes crafting descriptive variations ("eyes like lime cordial?... Glittering emeralds?"). In a chance sweet-shop encounter, she befriends Belgian refugee Hector Perot, a fastidious boy staying for a time nearby ("our own little immigrant," his hosts call him). After leaving her journal at her dance studio one evening following a charitable "Befriend the Foreigners" concert, Aggie returns to find a disagreeable local woman dead beneath the titular instrument. When an anonymous note with clues to the murderer's identity appears, the children jump on the case, much to the delight of a prolific reporter and the keen frustration of the constabulary. Though Perot's presence adds little more than Easter eggs (e.g., his namesake's phrasing habits) to the otherwise well-plotted mystery, he is set up to play a larger role in future installments. Jocelyn (One Yellow Ribbon) 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. Character portraits and chapter heading spot art from Follath (Joy) add whimsical appeal. Ages 10--up. (Feb.)

In 1902 Torquay, England, twelve-year-old Aggie befriends a Belgian refugee, Hector Perot, and investigates a murder roiling the town. When Mrs. Eversham, known throughout town for her sharp tongue and bad temper, is found dead on the floor of her sister-in-laws dance studio, Miss Marianne is the prime suspect. Aggie is certain her beloved dance teacher is innocent, so she evades adult oversight to solve the crime (with Hectors help). Plenty of red herrings keep Aggie discovering and discarding clues, and she finds as her investigation intensifies that the adults of Torquay appreciate her assistance less than they should. The young characters have a good deal of autonomy, driving a plot where parents, grandparents, and police officers are merely tolerated presences in the childrens world. Aggie, an observant outsider, is an engaging protagonist, with wide-eyed curiosity balanced by acute insights about many of the people in her community. Jocelyn keeps readers guessing throughout the book, but the eventual reveal of the perpetrator is believable, carefully clued, and satisfying. A solid dose of tart wit (Irma Eversham will be honored by more people as she enters her eternal slumber than she spoke to civilly in all of 1902) makes it an extra-enjoyable read; readers will eagerly anticipate the (hinted-at) further adventures of Aggie and Hector. An authors note explains that the story is inspired by Agatha Christies childhood, and while Christie fans may pick up on the many subtle references to her books and characters (Hercule Poirot, Miss Marple), the mystery stands on its own.
