Religious maniacs, militant Suffragettes and Vegetarians. None of these appear in this story, which is a good thing, as Petticoat Katie and Sledgehammer Girl investigate the case of the missing Feejee mermaid on behalf of the enchanting Mr Scipio Jones - the only black man in London to have scaled Mont Blanc.
Who is Mr Camembert, and will Petticoat Katie discover more than she bargained for in his Cabinet of Curiosities? And will Professor Digbeth of the Natural History Museum (Mammals section) meet his match in Sledgehammer Girl?
