Uncle Willie has come to stay with the Redpaths for the holidays. It is just their luck for him to be found dead the morning after Christmas day, dressed in his Santa Claus costume, seemingly poisoned by his favourite chocolates. Or was there something sinister in the mince pies? If so, was it the ones stashed in his room or those sent to him mysteriously by post? More importantly, since his will was recently redrafted, who stands to gain by this unseasonable crime?

It's 1811, and the threat of revolution haunts the upper classes of King George III's England. Then a beautiful young woman is found savagely murdered on the altar steps of an ancient church near Westminster Abbey. A dueling pistol found at the scene and the damning testimony of a witness both point to one man - Sebastian St. Cyr, Viscount Devlin, a brilliant young nobleman shattered by his experience in the Napoleonic Wars.

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?

Wealthy Sir Hubert Handesley's original and lively weekend house parties are deservedly famous. To amuse his guests, he has devised a new form of the fashionable Murder Game, in which a guest is secretly selected to commit a 'murder' in the dark, and everyone assembles to solve the crime. But when the lights go up this time, there is a real corpse....

In the smoke-wreathed gloom of a Parisian salon, Detective Bencolin has summoned his allies to discuss a peculiar case. A would-be murderer, imprisoned for his attempt to kill his wife, has escaped and is known to have visited a plastic surgeon. His whereabouts remain a mystery, though with his former wife poised to marry another, Bencolin predicts his return. Sure enough, the detective's worst suspicions are realised when the beheaded body of the new suitor is discovered in a locked room of the salon, with no apparent exit.
