Montgomery Bonbon Series : Titles in Order

Book 4
As the witty murder-mystery series continues, Bonbon returns for a pyrotechnic display aboard ship—until a shocking demise puts a damper on the festivities.

Shenanigans are once again afoot in the town of Widdlington, and this time they’re on board the Dreadnowt—a galleon that’s set to host a fireworks display for the town. Bonnie Montgomery and Grampa Banks are on board as guests, but just after sundown, a fog rolls in and a terrible cry is heard over the crash of the waves. Captain Valancourt stumbles out of the mist, dripping wet and covered in red welts the like of which a sea monster would leave behind, and is soon pronounced dead by the doctor on board. The crowd is shocked, and Bonnie’s fishy-o-meter is off the charts. While Inspector Sands takes over as captain, Bonnie transforms into Montgomery Bonbon, and it’s not long before she’s laid anchor on her prime suspects. Can Montgomery Bonbon hoist his moustache and figure out which scallywag is responsible for the death of the ancient mariner?
Book 3
Bonbon is back in the third installment of the clever and funny illustrated murder mystery series. But tensions run high when she’s surrounded by crooks.

Bonnie Montgomery (as her case-cracking alter ego Montgomery Bonbon) has been tasked with delivering a priceless diamond to Adderstone Manor, the home of retired master thief Fergus Croke. The plot thickens faster than a good roux when Croke is found dead hours later, and every one of his four protégés is suspected of the dirty deed. But when everyone is a crook, how does even the great Bonbon know where to begin?
With the help of Grampa Banks and an undercover best friend, it’s not long before Bonbon uncovers hidden identities, motives a-many, and a rather surprising hedge maze full of monkeys. But can they catch the killer before it’s too late?
Book 2
Bonbon is back in the second installment of this illustrated murder mystery series. The gentleman detective can’t get away from murder—even on vacation.

Bonnie Montgomery is finally getting a vacation from cracking cases as her alter ego, Montgomery Bonbon. But something terribly fishy happens the moment she and Grampa Banks arrive on Odde Island—and it’s not just the smell of the harbor. There’s been a mysterious death at the lighthouse, and what everyone assumed was an accident is setting Bonbon’s mustache all aquiver: something is Highly Suspicious. When a second death takes place, Bonnie is sure the two are connected. But can she solve this case alone, or will she need double the detectives to solve double the murders?
Book 1
"Comedian Beckett-King’s sparkling series-starting debut delivers constant laughs and witty rejoinders." —Publishers Weekly (starred review)

From a rising stand-up comedian and exciting new talent in children’s fiction comes a brilliantly funny murder mystery series that BBC Radio called “Knives Out meets Poirot—but for children!”

Bonnie Montgomery is the world’s greatest detective. Not that anyone—other than Grampa Banks—has heard of her. But they will have heard of Montgomery Bonbon, the gentleman detective with the bristly mustache, fashionable beret, and accent that’s hard to place. Montgomery Bonbon is responsible for solving many high-stakes crimes, including unmasking the Emmental Bandit, restoring the Rusakova diamonds to their rightful owner, and busting an international owl-smuggling ring, resulting in the arrest of over twelve owls.

But now Montgomery Bonbon is needed on a case much closer to home, at the Hornville Museum in Bonnie’s hometown of Widdlington, where a mysterious death has occurred. Don’t look too carefully, however—from certain angles, Montgomery Bonbon looks suspiciously like a ten-year-old girl . . . Brimming with charm and wit, this debut offering from comedian and writer Alasdair Beckett-King and best-selling illustrator Claire Powell is a delightful modern take on the classic whodunit.
