Former IRA enforcer and deadly assassin, Sean Dillon, returns in the stunning sequel to EYE OF THE STORM, from number 1 bestselling author, Jack Higgins.
Thunder Point: St John, the Virgin Islands, 1992

For once, the lone diver's treasure was priceless: a German U-boat, sunk in American waters three weeks after the end of the war. Inside: final proof that Reichsleiter Martin Bormann escaped from Hitler's bunker with the Third Reich's hideous secrets intact.

Among them: the names of British Nazi sympathisers some of them pillars of the establishment and the devastating document known as the Windsor Protocol.

For the sake of national security, the U-boat must be destroyed. And no questions asked. Even if it means persuading Britain's most wanted IRA terrorist to take on the job...
