In the novel 4.50 from Paddington, young Thomas Eade is mentioned by Miss Marple. He is the son of the bank manager in St. Mary Mead, who always was out to shock people. He went to the West Indies, but returned after the death of his father. He inherited a rather large sum of money, and Miss Marple said that he had always been better at spending money than making them.
Cedric Crackenthorpe reminded Miss Marple of young Mr Eade.
