A blizzard has hit England. In the tiny village of Sittaford, on the fringes of Dartmoor, a party of six is gathered in Sittaford House, home of Captain Trevelyan.
He has rented the house out for the winter and is staying in a nearby village.
As evening draws in, a seance is proposed. But it reveals more than they had anticipated - Trevelyan dead, spells out the board.
Slowly the table begins to rock again, spelling out the word M-U-R-D-E-R.
Is it true? And who would kill a man who doesn't have an enemy in the world?
