Mr Pim Passes By

In A. A. Milne's comic novel, Mr Pim Passes By, chaos prevails when the absent minded Mr Pim calls in to see George Marden, owner of Marden House. George is a fine upstanding citizen and a stickler for doing the right thing. He has a devoted wife, Olivia, and is ward to his somewhat flighty niece, Dinah. Quite innocently, Mr Pim upsets the equilibrium of the Marden household when he casually announces that he's recently seen an ex-convict from Australia, named Telworthy.

This character sounds awfully like Olivia's first and supposedly deceased husband and if he's really still alive, then Olivia is a bigamist!
