The world of the greatest detective returns in the fourth installment of a highly clever, funny, and illustrated mystery novel series. In the city of Widdlington, scandalous adventures happen once again, this time on the Dreadnowt—a schooner that will host a fireworks display for the town. Bonnie Montgomery and Grampa Banks are passengers on the ship, but shortly after sunset, a fog covers the area and a terrifying scream is heard amid the stormy waves. Captain Valancourt emerges from the fog, with drops dripping from him and covered in red wounds, similar to those left by a sea monster, and is soon diagnosed as dead by the ship’s doctor. The crowd is shocked, and Bonnie’s detective skills are on point. While Inspector Sands takes on the role of captain, Bonnie transforms into Montgomery Bonbon and quickly identifies the main suspects. Can Montgomery Bonbon solve… the ancient sailor’s crime?
