Meet the world's greatest detective in disguise! With a false moustache, a beret and a trench coat, 10-year-old Bonnie Montgomery becomes renowned super sleuth ... MONTGOMERY BONBON.

A brilliantly funny murder mystery from stand-up comedian, podcaster and filmmaker Alasdair Beckett-King, with illustrations by Claire Powell.
"Brilliant, hilarious shenanigans, and lots of them. Montgomery Bonbon is on the case in their most bonkers adventure yet." Thomas Taylor

Bonnie Montgomery (as her case-cracking alter-ego Montgomery Bonbon) has been invited to Adderstone Manor by Fergus Croke, whose prized diamond has gone missing. Croke is a retired master thief who suspects one of his four protégés of the dirty deed - but when everyone is a crook, how does even the great Bonbon know where to begin?

The plot thickens faster than a good roux when the only unsuspicious member of the household, Croke's loyal butler, is found dead in the grounds - and it's not long before Bonbon uncovers hidden identities, motives a-many, and a rather surprising hedge maze full of monkeys. Can Bonbon, Dana and Grampa Banks uncover the missing gem and catch the thief and killer - and are they one and the same?
