Tom Carter approaches Hetty with claims that his brother Harry was murdered by housekeeper Ella Parsons,who had been systematically robbing him. Hetty sends Robert in to pose as a wheelchair-bound long lost relative of the deceased with Geoffrey as his chauffeur. It becomes clear that Ella is not the person she claimed to be though she soon tumbles to the real cause for Robert's presence. However she is not the only person not to have been honest with the Wainthropps.
