It is linked, by the central character of Joe, to the Poliakoff drama Capturing Mary which was aired (on BBC Two) on 12 November 2007.
The play revolves around the character of Joe (who is also the narrator), a teenager who has just left school and finds himself employed by Elliot Graham, an agoraphobic billionaire.
None of the staff remains for very long—Joe's mother disappears off to Spain with her new lover, the first caretaker smashes most of the plates before very nearly throwing himself off the roof, and even a homeless person whom Joe invites back for company senses the bad vibes about the place.
He even sends Joe onto the Antiques Roadshow with a collection of gold snuffboxes worth nearly a million pounds to see if he can glean any more about their origin from the specialist Geoffrey Munn.
The drama ends with Joe himself moving on, and Graham now using his money for good, and having traced the rightful owners of the antiques.
