Oswald's Tale: An American Mystery is a 1995 non-fiction book by Norman Mailer, ISBN 0-679-42535-7. It amounts to a detailed biography of Lee Harvey Oswald (1939–1963), the assassin of US President John F. Kennedy. The book includes an exhaustive examination of his movements in the years, and particularly in the months, leading up to Kennedy's assassination on November 22, 1963, and Oswald's own death two days later. Knitted into the story of Oswald's life are Mailer's suppositions on his state of mind and motivations. The Oswald that Mailer depicts is a single-minded and vain individual convinced of his own destiny and importance who suffers a series of defeats and frustrations, and who killed the President in a desperate search for achievement. When Oswald returns to Dallas in 1963 with his wife and daughter, he still has dreams, still sees himself as "an instrument of history," and is still frustrated and unhappy. His claim of responsibility for the April, 1963, assassination attempt on Gen. Edwin Walker, a John Birch Society supporter, whether or not it is true, shows him acting out his belief that he is an instrument of history in the months leading up to Nov. 22, 1963. Six months after the assassination attempt on Walker, Oswald takes advantage of the accident of history that has brought the JFK motorcade past the window of the Depository where he works, and he acts out his self-declared destiny.
In the original review of the book in the New York Times by Thomas Powers, the work is described as "marvelous" Powers writes, "All of this is described wonderfully well. Mailer's account adds many new characters and incidents to the story told by Ms. McMillan, but it is also distinguished by a brilliant linguistic invention, a kind of Mailer-patent Russian-English that captures Russian rhythms not only of language but also of thinking and feeling about love, work and the ways of the world."
Michiko Kakutani of the New York Times described Oswald's Tale as a "long-winded and ultimately superfluous book". According to Kakutani: "Mr. Mailer declines to use his enormous gifts as a reporter and novelist to create an unvarnished portrait of his subject (the way he did with Gary Gilmore in his 1979 masterpiece, The Executioner's Song), but instead clumsily tries to force his material into an unyielding cookie-cutter shape. The result is a book that succeeds simultaneously in being boring and presumptuous, derivative and solipsistic." She also wrote: "Mr. Mailer willfully veers even further into the realm of imaginative fancy than Don DeLillo did in his powerful 1988 Oswald novel Libra."
