A country house murder mystery classic, as a party find themselves snowed-in on Christmas Eve with a murderer among them... The snow is thick, the phone line is down, and no one is getting in or out of Warbeck Hall. All is set for a lovely Christmas, with friends and family gathered round the fire, except as the bells chime midnight, a murder is committed. But who is responsible? The scorned young lover? The lord's passed-over cousin? The social climbing politician's wife? The Czech history professor? The obsequious butler? And perhaps the real question is: Can they survive long enough to find out?
