Gentle chaos sets in when the absent-minded Mr Pim calls in to see George Marden, bearing some innocent news... George is a fine upstanding citizen and a stickler for doing the right thing. He has a devoted wife, Olivia, and is guardian to his somewhat flighty niece, Dinah.But his careful peace is broken when Mr Pim casually announces that he’s recently seen an ex-convict from Australia, Telworthy. The only thing is that the character sounds awfully like Olivia’s first, and supposedly deceased, husband… and if he’s eally still alive, then Olivia is a bigamist.
