Richard Ainsworth is preparing for the Christmas of his dreams: quiet, no guests at his French B&B and his favourite films on the TV. None of which seems on the cards when his rural peace is shattered by the unexpected arrival of a familiar face. Valerie d'Orcay has hotfooted it from Paris with her chihuahua in tow and an invitation to a Christmas themed murder mystery game.
Richard begrudgingly dresses up as Father Christmas, but the costume becomes the least of his worries when he realises this isn't a game to everyone. As other guests arrive to join the hunt, can Richard work out who is the victim - and who is murderer?
