Although the story of Uncle Dynamite concerns Bill Oakshott's struggle to find ways of getting his girl while financing his inheritance at Ashenden Manor, the real hero of the book is Frederick Altamont Cornwallis, fifth Earl of Ickenham. This noble lord who describes himself as 'one of the hottest earls that ever donned a coronet' was one of his creator's favourite characters, featuring in three other novels. Lord Ickenham sees it as his mission to bring a little joy into the lives of others, and on this occasion he surpasses himself.
