U.N. Owen

U.N. Owen is the pseudonymous identity of the unknown host who lures ten guests to Indian Island and orchestrates their deaths as a form of vigilante justice against individuals who have escaped legal punishment. The name is revealed to be a deliberate pun on "Unknown," and the figure behind it is ultimately disclosed as the retired judge Lawrence John Wargrave, who uses the alias to execute a meticulously planned mass murder that the law cannot touch.

Identity and Origin of the Name

The name U.N. Owen first appears in the letters and telegrams that bring each guest to Indian Island. The judge, Lawrence John Wargrave, is the first to notice the pattern: the host signs himself "Ulick Norman Owen" in some correspondence and "Una Nancy Owen" in others, both sets of initials being U.N.O. Wargrave points out that "by a slight stretch of fancy, UNKNOWN" is the intended meaning. The name is thus a transparent alias, a mask for a person who does not wish to be identified. The guests realize that none of them has ever met anyone named Owen; the invitations were fabricated using personal details about each guest's acquaintances and circumstances.

Purpose and Method

U.N. Owen's stated purpose is to execute judgment on individuals who have committed murders that the legal system cannot punish. As the police later summarize, "U. N. Owen dealt with cases that the law couldn't touch." The victims are accused of specific crimes: Anthony Marston for killing two children in a car accident, Mrs. Rogers and her husband for neglecting an elderly employer to death, General Macarthur for sending his wife's lover to his death in war, Emily Brent for driving a pregnant servant to suicide, Vera Claythorne for drowning a child in her care, Philip Lombard for abandoning twenty-one men to die in East Africa, Dr. Armstrong for operating while drunk and killing a patient, Blore for perjury that sent an innocent man to prison, and Wargrave himself for the judicial murder of Edward Seton. The method is to isolate the island, then kill each victim in a manner that mirrors the nursery rhyme "Ten Little Indian Boys," which is framed in every bedroom.

Key Actions and Development

U.N. Owen's plan unfolds over several days. On the first evening, a gramophone record accuses each guest by name. That night, Anthony Marston dies from cyanide poisoning, and Mrs. Rogers dies from an overdose of chloral hydrate. The next day, General Macarthur is bludgeoned to death, and Rogers is killed with an axe while chopping sticks. Emily Brent is injected with cyanide after being drugged. Wargrave then stages his own death, dressing himself in a red curtain and grey wool to mimic a judge's robes and wig, and is "found" shot in the head. After this fake death, Wargrave, as U.N. Owen, lures Dr. Armstrong to the cliff edge and pushes him into the sea. He then returns the revolver to Lombard's room and watches from the house as Blore is crushed by a marble bear clock, Vera Claythorne shoots Lombard, and Vera hangs herself in her bedroom. Finally, Wargrave shoots himself using an elastic cord and eyeglasses to make the revolver fall away from his body, completing the illusion that he too was a victim.

Thematic Significance

U.N. Owen represents the ultimate expression of vigilante justice, a figure who believes himself above the law and capable of meting out punishment where the legal system has failed. Wargrave's confession reveals that he was driven by a "strong sense of justice" combined with a "sadistic delight in seeing or causing death." He saw himself as an artist in crime, creating a "fantastical crime—something stupendous—out of the common." The name U.N. Owen thus becomes a symbol of the unknown, the hidden hand of retribution that operates outside the boundaries of society's institutions. The police are left with an unsolved mystery, and only Wargrave's bottled confession, cast into the sea, explains the truth. The novel ultimately questions whether such extra-legal justice can ever be justified, and whether the desire for absolute justice can itself become a form of madness.
