Montgomery Bonbon #4

Sabotage at Sea

Rate this book
The world's greatest detective is back in the fourth instalment in a brilliantly clever, funny and highly illustrated murder mystery series.

Shenanigans are once again afoot in the town of Widdlington, and this time they're on board the Dreadnowt – a galleon ship 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 solve … the crime of the ancient mariner?

I’m so glad that Montgomery Bonbon is back with a new murder mystery for her to solve. Bonnie Montgomery changes into a disguise as Montgomery Bonbon a detective, with always adding a detective rain coat, and a moustache.On the Dreadnowt , ship in Widdlington harbour, Captain Roger Valancourt is in charge. What should have been a pleasant evening at the ship’s firework display turns into a murder scene. Captain Valancourt has been attacked. He is dead, with strange red marks on him. Can Bonnie in disguise as a detective Montgomery Bonbon find out who the suspect is? And that’s not all folks, there’s a little more mystery to for Montgomery Bonbon to solve. 9-12 years will adore the who collection of Montgomery Bonbon.

AWANTURA NA MORZU, czyli tom 4 serii o dziwnym detektywie - dziewczynce w przebraniu i jej dziadku - MONTGOMERYm BONBONie. Te książki są trochę zabawne, trochę szalone, trochę postrzelone. Fabuła zawsze dość prosta, ale ma swój urok, jest niewymagająca, można nawet rzec, że trochę banalna, ale nie szukam w tej serii wybitności... tylko lekką przekąskę i to też dostaję.
Tym razem rzecz dzieje się w iście pirackim stylu i to ma klimat. Może nie jestem jakąś ogromną fanką pióra ALASDAIRa BECKETTa-KINGa, ale trzeba mu przyznać, że wymyślił oryginalny styl i stworzył rozpoznawalną bohaterkę. Jest też obdarzony specyficznym poczuciem humoru, co przekłada się na książki o BONBONie.
Tutaj akcja dzieje się - ze strony na stronę. Wyskakują to z jednej strony, to z drugiej podejrzani i nawet nie zostaje oszczędzona mama Bonnie - Liz... sprawa więc robi się prywatna. Tak jak wspomniałam jest to książka "przekąska" dla dorosłych, dla młodszych czytelników też nie bardzo angażująca intelekt, ale zwracająca uwagę swymi gagami.
Należy też zwrócić uwagę na bardzo ładne wydania. Mamy twarde, kolorowe, naprawdę barwne okładki i ilustracje CLAIRE POWELL, które są ujmujące i humorystyczne. Wizualnie idealna seria na prezent, a jeśli szukacie lekkiej zagadki - ale z zawsze z trupem - tylko jakby w krzywym zwierciadle - to dobrze trafiliście.

Bonnie and Grandpa Banks on the high seas, what a treat!
When Mongomery Bonbon and Grandpa Banks head for the high seas on a pirate ship, the plan is just to watch the fireworks go off. However the fireworks go off all at once and poor old Liz Mongomery, Bonnie Montgomery is mum, is arrested. Why should this bother the great detective? Because Montgomery Bonbon, is in fact Bonnie Mongomery (in a beret and false moustache). Can Bonnie save her mum, solve a murder and avoid the awful creations the ships cook comes up with? If anyone can, Bonnie can.

I love this series. I cannot praise it highly enough, This is the book to give to a child who has read all the ‘Wimpy Kids’ or ‘Lottie Brooks’ and wants something new. This series just keeps getting better and better and I cannot wait for the next one.

Sabotage at Sea, the fourth and latest book (and probably my favourite), sees Montgomery Bonbon (aka Bonnie Montgomery when the mustache comes off), aboard a ship on what was supposed to be a night of celebration but ends up with a demise that creates a new case for the detective. As usual, Grampa Banks and Dana are by Bonbon's side to offer their assistance but this time Bonnie's mom is also involved in the case, coming face-to-face with Montgomery Bonbon for the first time.

With the usual medley of colourful characters (both new and recurring ones), I found this book even more entertaining than the previous three. The mystery keeps the reader guessing and will take you on a rollercoaster ride of discoveries. The book is brimming with hilarious moments and, together with the illustrations and the witty writing, it is sure to delight both its middle grade readers as well as the adult ones. I cannot wait to see what the fifth installment in this series is going to be like!

I love this series! They’re such fun and gorgeously illustrated. I love Montgomery’s mix of languages used - properly makes me smile! This one takes place on a pirate ship, which brings along many ship/pirate jokes (much to my delight). DELIGHTED that there’ll be more!

The newest book in the series! This time BonBon plays a home game as the mystery takes place at Bonnie’s town.


🥰 The mystery was oh so much fun! And confuddling. Not just to the reader but also to BonBon. Nothing is what it seems and people are very dedicated to keeping secrets.
🥰 I also love BonBon’s character! Bonnie is really adding a lot of flair and personality to it all. Though I do hope that she goes to learn some more foreign words to add to her vocabulary, I would love to see that!
🥰 Reading about the town of Widdlington, including the fair/carnival on the pier and the fun things to do there.
🥰 Dana is here and she is such a fun addition to the team in this one. Helps out with some facts, helps with the costume, helps with the investigation in a non-intrusive/annoying way, I loved seeing her figure out pranks (though she is still not doing that well with them, haha, but it is the thought that counts and she is having fun).
🥰 Grandpa Banks! Such an interesting and fun character and I love how he helps out his granddaughter with her investigations (though he is not allowed to do much exercise as the doctor has forbidden that).
🥰 Learning about the boat/ship.
🥰 That inspector is still an idiot, it amazing me that she keeps that job, haha, I guess no one else wants to do it. Or maybe she is just the brightest bulb of all the police force.
🥰 The puns! Loved them!
🥰 A light dose of 4th wall breaking (hope the author has made some time to do that, haha).
🥰 The mom! She was such a fun character and I really liked seeing so much of her. I was at times a bit worried she may be an annoyance factor, I have read one too many MG with parents butting in, but thankfully, she stays mostly on the side. Until she goes to do her own investigation.
🥰 The ending, oh I liked that one, especially what mom said at the end.
🥰 The cover, the illustrations. The style is just fantastic and I love every bit of it.
🥰 A new book is coming! I always want more BonBon and so I am delighted a new adventure is coming~

All in all, this was such a delightful book again with plenty of good mysteries and more! I would recommend it and the series to all~
