Mr Charles Dickens' Authentic Blackballs In A Jar

Victorian London, 1888. A killer is on the loose and there's plenty more Dundee cake, so retire with my illustrious ancestor Mr Willis, Mr Dickens and the Prime Minister Mr Gladstone for an evening of tip top entertainment at No.10. A transcript of the tale related by my great, great, great grandfather to various aghast gentlemen at the fireside of their London club, Christmas Day 1897.
