Hunting Eichmann: How a Band of Survivors and a Young Spy Agency Chased Down the World's Most Notorious Nazi is a book by Neal Bascomb.

A network of concentration camp survivors and Nazi hunters in Europe, including Simon Wiesenthal, pursued leads on Eichmann's whereabouts and passed information to the government of Israel and its foreign intelligence agency, Mossad.

A team of agents from both Mossad and Shin Bet (Israeli internal security) traveled to Buenos Aires, Argentina, where Eichmann was hiding, and captured him in May 1960.

He was taken to Israel, tried and convicted of war crimes in 1961, and executed by hanging in June 1962.

[1] A review in Library Journal commended the author's "singing prose style", as well as "The details elicited from Bascomb's interviews with a startling range of people associated with the events [that] freshen interest in this famous story".
