Todd Otterman thought about trying to kick in the door but dismissed the idea. There was no way of telling how strong it was, and the door was certain to be locked. He had two advantages: he had surprise on his side and he had a handgun. The sniper would have to swing his rifle through almost one hundred and eighty degrees to get a shot at the door. Otterman was breathing heavily and he could see that the two rookies were trembling. He motioned with his free hand that he was going to shoot out the lock, and that the two Academy rookies were to kick the door, then move out of the way.

They nodded and watched as Otterman mouthed a quick count: Three, Two, One, then fired at the lock. The metal screeched and the wood splintered and immediately the two rookies kicked at the door, close to the lock. The door flew inwards and Otterman stepped across the threshold, the gun held firmly in both hands.

“Secret Service!” he yelled. “Drop the weapon!”

The sniper began to turn and made no attempt to release his grip on the rifle. There was no way the Secret Service agent was going to take a chance with the President’s life. He shot the sniper twice in the back.

Carlos centred his telescopic sight on the President’s chest as he looked through the window of the sky box. He steadied his breathing. It would be so easy to pull the trigger without waiting for Lovell. He had a clear shot and the President was standing stock still, his eyes on the Prime Minister far below. Carlos was the closest sniper to the target and his bullet would take less than a second to blow the man apart. The difference in drop between the target on the pitcher’s mound and the sky box would be minimal. It would be so simple to fire now. The anticipation was almost painful. He smiled to himself and blocked such reckless thoughts out of his mind. He had to stick to the plan. His plan.

Carlos was ready. He’d compensated for the wind drift based on the figures Farrell had given him, and he had already made allowance for the fact that it had been Dina Rashid and not himself who had calibrated the scope.

He heard something move in the corridor outside but he blocked out the noise. He had to be totally focused on the target. Nothing else mattered.

Lovell’s voice in his ear almost caught him by surprise. “Target sighted,” said the laconic West Virginian accent. “Countdown starting. Five . . . four . . .”

Joker looked across the field at the pitcher’s mound, which was about thirty yards away from where he was standing. Secret Service chatter filled his ear again. The Prime Minister was drawing back his hand to throw, amid good-natured catcalls and whistles from the crowd. The First Lady was preparing to applaud. The Secret Service agents and the Prime Minister’s own bodyguards were all concentrating on the crowd. None of them was looking at the airship. A chill ran down Joker’s spine. He pressed the binoculars to his eyes and focused them on the gondola below the blimp. His hands were shaking and he fought to keep them steady.
