The Bones of St Nicholas

Dr. Jasper Parkway has booked an overnight stay in a reputedly haunted church on Christmas Eve. However, much to his dismay, he is soon joined by unwanted guests Pierce and Posy, who have even brought their own sleeping bags. Together with the eccentric warden Dick, it doesn't look like Jasper is going to be lonely this Christmas. Even though sherry, biscuits and Yuletide phantoms are on offer, why is Jasper so keen to be left to his own devices?
