At a time when Edwardian Britain seemed a golden place, American physician Hawley Harvey Crippen and his wife, Belle, lived among the suburban villas of North London. After supper on January 31, 1910, the guests departed, and Crippen poisoned Belle, dismembered her, and buried part of her remains in the coal cellar. Crippen never confessed, taking the secrets of the crime with him when he was finally hanged for murder. It is assumed that Crippen killed for the love of his mistress, Ethel Le Neve. Living together as man and wife, but under intense suspicion, they fled disguised as father and son. The chase was widely reported in Europe and America, and Crippen was finally apprehended. In Supper with the Crippens, David James Smith reinvestigates this celebrated murder case.
