Mr. Roger Havering

Havering moves through the world of fashionable London, where reputations are made of furs, jewels, and the right introductions, and where a robbery at a grand hotel becomes a social event as much as a crime. He is the kind of man whose ease in that world makes him useful and slightly suspect at once, since Poirot's cases turn on who noticed what and who chose not to. His presence gives the investigation its human texture, a reminder that theft among the wealthy is rarely only about the object taken.
