Summary 1

At Swim-Two-Birds presents itself as a first-person story by an unnamed Irish student of literature. The student believes that "one beginning and one ending for a book was a thing I did not agree with", and he accordingly sets three apparently quite separate stories in motion. The first concerns the Pooka MacPhellimey, "a member of the devil class". The second is about a young man named John Furriskey, who turns out to be a fictional character created by another of the student's creations, Dermot Trellis, a cynical writer of Westerns. The third consists of the student's adaptations of Irish legends, mostly concerning Finn Mac Cool and mad King Sweeney.

In the autobiographical frame story, the student recounts details of his life. He lives with his uncle, who works as a clerk in the Guinness Brewery in Dublin. The uncle is a complacent and self-consciously respectable bachelor who suspects that the student does very little studying. This seems to be the case, as by his own account the student spends more time drinking stout with his college friends, lying in bed and working on his book, than he does going to class.

The stories that the student is writing soon become intertwined with each other. John Furriskey meets and befriends two of Trellis's other characters, Antony Lamont and Paul Shanahan. They each become resentful of Trellis's control over their destinies, and manage to drug him so that he will spend more time asleep, giving them the freedom to lead quiet domestic lives rather than be ruled by the lurid plots of his novels. Meanwhile, Trellis creates Sheila Lamont (Antony Lamont's sister) in order that Furriskey might seduce and betray her, but "blinded by her beauty" Trellis "so far forgets himself as to assault her himself." Sheila, in due course, gives birth to a child named Orlick, who is born as a polite and articulate young man with a gift for writing fiction. The entire group of Trellis's characters, by now including Finn, Sweeney, the urbane Pooka and an invisible and quarrelsome Good Fairy who lives in the Pooka's pocket, convenes in Trellis's fictional Red Swan Hotel where they devise a way to overthrow their author. Encouraged by the others, Orlick starts writing a novel about his father in which Trellis is tried by his own creations, found guilty and viciously tortured. Just as Orlick's novel is about to climax with Trellis' death, the college student passes his exams and At Swim-Two-Birds ends.
