Anthony Marston is one of ten people summoned to Indian Island by Lawrence Wargrave in Agatha Christie's novel, 'And Then There Were None,' who have committed murder in a way that the law cannot prove or punish them for. He is the first of the ten to die.
Anthony Marston is described as a man with a well-proportioned body, crisp hair, tanned face and blue eyes. He was born to a wealthy family and although he owns an expensive car, is a very reckless driver who loves speeding. A year before the events on Indian Island, Marston whilst driving at night, ran over and killed two children, John and Lucy Combes. Although clearly the one at fault a few of his wealthy friends intervened preventing Marston not only from losing his driver's license but facing criminal charges. As such he was only banned from driving for a year.
Marston himself feels no remorse for the incident as he lacks any kind of moral responsibility. Because of this lacking, Wargrave decides that Anthony should be the first one to die, not because Marston is the least guilty of the murderers but because Wargrave knows he cannot break Marston or make him feel remorse. As such Marston, whose guilt could still arguably be the lightest, is the first to die, being spared the strain of the more cold-blooded killers. On the first night of their gathering, Marston chokes to death after his drink is poisoned with potassium cyanide, corresponding with the verse of the 'Ten Little Indians' rhyme, "One choked his little self."
