A brilliant, seat-of-your-pants hostage-taking and daring SAS rescue mission of the Iran Embassy in London in 1980, this is Ben Macintyre at the very height of his story-telling powers.

On April 30, 1980, six heavily armed gunmen burst into the Iranian embassy on Prince’s Gate, overlooking Hyde Park in London. There, they took 26 hostages, including embassy staff, visitors, and three British citizens. A tense six-day siege ensued—all on television, over a Bank Holiday weekend—in which police negotiators and psychiatrists sought a bloodless end to the standoff, while the SAS laid plans for a daring rescue mission: Operation Nimrod.

This mission marked a fundamental turning point in global history, when Middle Eastern terrorism arrived in the West. Britain had experienced IRA terrorism before, but never an international terrorist incident on this scale. It was a precursor to the brutal Iran-Iraq War that would follow, in which millions perished. Yet there exists to this day no full account of the week-long siege and gripping rescue.

Drawing on interviews with police, hostages, terrorists and key SAS figures, and cutting through the sensationalism and misinformation, bestselling historian Ben Macintyre (author of Sunday Times #1s Colditz, The Spy and the Traitor and SAS: Rogue Heroes) goes deep into the archives with exclusive access to tell the story of what really happened and give the first definitive account of a moment that forever changed the way the nation thought about the SAS—and itself.
