This week the mystery surrounds Clare and her partner John who live in – as Judi Love calls it - a "proper yard" in Guildford, Surrey.
Trying to pass themselves off as the lady of the manor is one Clare who has a moment over a watering can, a 'Klara' from Slovakia who says most people think she is the cleaner not the homeowner, a former air hostess who met John on a flight, and another Clare who claims to have been living in the property all her life.
But the plot really thickens when John makes a last-minute appearance, sending the panel into a tailspin.
