This is one of our must-reads for readers aged 8+ that love detective series like An Eerie-on-Sea Mystery, Murder Most Unladylike Mystery, The Sinclair's Mysteries and Scarlet and Ivy books.
You've never met a detective like Bonnie Montgomery, a well-dressed gentleman detective who (apart from the hat and moustache) looks suspiciously like a 10-year-old girl. In each book, she's got a mystery to solve, from a highly suspicious death at the Hornville Museum to a mysterious death at Leerie Lighthouse... and more!
With lovely black-and white illustrations throughout, this is the perfect cosy mystery to tuck into. Do also take a look at our recommendations for the Best Mysteries and Detective Books for Kids.
