The fifth mystery by bestselling author Janice Hallett, a fiendishly clever story of missing persons, murder, and battling pub quiz teams

* THE INSTANT SUNDAY TIMES BESTSELLER * 'Murderously good' - DAILY EXPRESS 'An addictive whodunnit' - iPAPER 'So clever, you'll want to read it again' - WOMAN AND HOME The answer is murder. The question is whodunnit? A quiet country pub stands empty, its windows boarded up. And its kindly landlords, Mal and Sue Eastwood, are missing. What could have happened? A lot of strange events occurred in the days before the Eastwoods disappeared. A murdered man pulled from the nearby river. An eccentric couple on a houseboat who claimed to be led by a spirit guide. And a mysterious new team who suddenly appeared and began winning every round at the weekly pub quiz - much to the anger of the locals. They must have been cheating, but no one could figure out how... Can you crack the case of the missing landlords? Someone's not been playing fair, so get the drinks in and see if you can get a perfect score.
