In the novel And Then There Were None, Anthony “Tony” James Marston was a young man that came from a wealthy background. He was described as "not a man, but a young God, a Hero God from some Northern Saga". He was six feet tall and had blue eyes, crisp hair, and a tanned face.
He was invited to Soldier Island, and was accused of killing John and Lucy Combes. In fact, his reckless driving caused the deaths of the two children near Cambridge. His car, a Super-Sports Dalmain, was described as "so fantastically powerful, so superlatively beautiful that it had all the nature of an apparition". Fred Narracott noted that it was one of the few times that a car like that had ever appeared in Sticklehaven.
Anthony Marston first appears when driving to Soldier Island. He rushed with his car past Dr Armstrong who turned out to be one of the guests and criticized him for his reckless driving. He was later driven to Soldier Island by one local boatman Narracott.
Marston was a friend of "old horse" Badger Berkeley, who had gone to Norway for a short period of time. The killer used Badger's name to lure Anthony into the island.
After dinner at Soldier Island a gramophone recording accused everyone of murder and pointed out that Marston had killed the Combes brothers earlier that year. Judge Lawrence Wargrave decided that the group should have left the island as soon as possible, but Marston didn't seem to agree. He died inmediately after from drinking a cyanide laced drink, thus making it U.N. Owen's first murder victim.
A General Macarthur suggested that his death was probably an accidental choking but Dr Edward Armstrong said that the glass contained cyanide. Another hypothesis was that he must have killed himself, but this one too wasn't valid since he wasn't a "suicidal type".
The culprit killed Marston first because the death of the Combes children was accidental yet Marston felt no remorse for what he had done. The next deaths were of the more cold-blooded murderers, like a governess who allowed a child to drown, a spinster who led a young girl to suicide, or a Mr Blore who made someone innocent die in prison.

He is one of the first guests to arrive on the island along with a Miss Brent. He later speaks with Lombard about how nobody did care about World War One anymore.

However in this adaptation Armstrong recognised his car and made a scene at dinner.
