Ten guilty strangers are trapped on an island. One by one they are accused of murder; one by one they start to die. In this superlative mystery comedy statuettes of little soldier boys on the mantel of a house on an island off the coast of Devon fall to the floor and break one by one as those in the house succumb to a diabolical avenger. A nursery rhyme tells how each of the ten "soldiers" met his death until there were none. Eight guests who have never met each other or their apparently absent.
