The Bourne Ultimatum is the third Jason Bourne novel written by Robert Ludlum and a sequel to The Bourne Supremacy (1986). First published in 1990, it was the last Bourne novel to be written by Ludlum himself.

After a message in the form of a murder at a carnival indicates his old enemy, Carlos the Jackal, has resurfaced, David Webb, aka Jason Bourne, works to find him. As the Jackal enters old age and his infamy fades, he decides that he will do two things before he dies: kill Webb/Bourne, and destroy the KGB facility of Novgorod, where the Jackal was trained and was turned away for being a maniac.

Carlos the Jackal uses a diverse collective of aged men devoted to his handiwork known as "The Old Men of Paris." The old men, who are mostly criminals, work for the Jackal in return for their family's comfort. Webb sends his wife and children to live with her brother, John St. Jacques, in the Caribbean for protection while Webb himself works with old friend and CIA agent Alexander Conklin, and to a limited degree, the CIA, to hunt down and kill the Jackal first.
