First appearance: M. Papopolous Breakfasts
As a supporting figure in The Mystery of the Blue Train, M. Papopolous is not background color—the story leans on what they do once the chapter opens.
The antique dealer who meets with M.
Papopolous moves through the story with the polished manners of a connoisseur, but his real business lies in the shadow market for precious stones, where reputations are quietly traded and rubies change hands without provenance. He knows the value of the Kettering ruby and the people who would pay for it, making him a natural conduit between the criminal world and Poirot's inquiries. His genial discretion and his willingness to talk, for a price, make him one of the most useful and least trustworthy figures in the investigation.
