Aggie Morton, Mystery Queen is a nostalgic historical mystery series inspired by the imagined childhood of Agatha Christie.
Set in Victorian seaside England, the books follow curious and clever 12-year-old Aggie Morton and her shy Belgian friend, Hector Perot, as they find themselves tangled in mysterious deaths—and use their wit and intuition to solve them. With a keen eye for clues and a growing sense of confidence, Aggie navigates puzzles, friendships, and the expectations placed on girls in her time.
Rich in atmosphere and gentle suspense, this series is perfect for readers who love classic whodunits, strong female protagonists and historical settings. The stories balance intrigue with humour and heart, and each book includes subtle nods to Christie fans while remaining completely accessible to young readers.
Ideal for children aged 9+, especially those who enjoy series like Enola Holmes or Robin Stevens’ Murder Most Unladylike.
