Meet Bonnie Montgomery, the 10-year-old who transforms into the renowned super sleuth, MONTGOMERY BONBON, complete with a false moustache, a beret, and a trench coat. This brilliantly funny murder mystery, written by stand-up comedian, podcaster, and filmmaker Alasdair Beckett-King, plunges young readers into a theatrical whodunit.

When playwright Cynthia Cecil collapses on stage during a local theatre rehearsal, the initial assumption of natural causes is shattered. Montgomery Bonbon overhears Cynthia’s final, unscripted word: 'Murder!' With the cast all having seemingly rock-solid alibis, Bonbon must untangle the lines of truth before opening night to expose a killer clever enough to commit the crime in front of an audience.
