Esta é A Caixa Midas por G. P. Taylor. É o livro um dos três que seguem Mariah Mundi.
Fresh out of school, young Mariah faces a new chapter of his life living in the Prince Regent hotel, built into the rock face of a cliff side. His job is to assist the magician in the stage shows held for the guests. Above ground, the guests are offered every form of luxury. Below ground, in the slimy, green-dripping walls of the basements, is where the magic show equipment is kept - and lurking in an Egyptian sarcophagus amongst scuttling sea-creatures is a secret that draws Mariah into the path of villainy, plots and possible death.
Esta resenha aborda o enredo muito mais a fundo e menciona o Capitão Caridade (apenas o começo da sinopse incluído):
Mariah Mundi, a colonial school boy who has lost his parents, has received an invite to work at The Prince Regent Hotel. On his train ride to the hotel, he meets Albion. Albion gives him a deck of cards and tells him to tell no one that he has received these cards. Also on his train ride he meets Isambard Black and Captain Charity.
Houve um filme feito com base neste livro (mas aparentemente diverge significativamente): A Maldição da Caixa Midas
