At the moment of impact Branson touched a second button on the fascia. The lead coach, slowing only by its hand-brake, was now doing no more than ten miles an hour when another small explosion occurred in the drinks cabinet at the rear, an explosion followed immediately by a pronounced hissing as if caused by compressed air escaping under very high pressure. Within seconds the entire compartment was filled with a dense, grey, obnoxious and noxious gas. The coach, almost immediately out of control as the driver slumped forward over the wheel, slewed slowly to the right and came to a rest less than two feet from the side of the road. Not that it would have mattered particularly if it had struck the safety barriers on the side of the bridge which were of a nature to withstand the assaults of anything less than a Chieftain tank.
The Presidential coach came to no harm. The driver had seen the lead coach's brake warning lights come on, braked, pulled left to avoid the slewing coach ahead and came to a rest beside it. The expressions of the twelve occupants of the coach expressed varying degrees of unhappiness but not, as yet, of alarm.
The police car and two motor-cycle outriders leading the motorcade had been curiously slow to observe the confusion behind them. Only now had they spotted the slewed coach and were beginning to turn.
In the rear coach everything was taking place with the clockwork precision that stemmed from a score of practice runs that had covered all conceivable potentialities. Van Effen jumped down from the left-hand door, Yonoie from the right, just as the two motor-cycle outriders pulled up almost alongside. Van Effen said: 'You better get in there fast. Looks like we got a stiff on our hands.'
The two patrolmen propped their machines and jumped aboard the coach. They could now no longer be seen by the returning lead police car and outriders so it was safe to take swift and efficient action against them, which was done with considerable ease not least because their attention had immediately been caught up by the sight of the bound figure lying sprawled on the floor in the rear aisle.
Seven men emerged swiftly from the doors of the coach. Five of those joined Van Effen and Yonnie and ran towards the other coaches. Two more ran back towards the crashed police car. Two others inside the coach swung wide the rear door and mounted what appeared to be a relatively harmless length of steel tubing on a tripod stand. Branson and Jensen remained where they were: the bound man on the floor, whose identity Jensen had taken over, regarded them all severally with a baleful expression but, beyond that, the options open to him were rather limited.
The two men who had run back towards the crashed police car were called Kowalski and Peters. They didn't look like criminals, unless a couple of prosperous young commuters from the stockbroker belt could be called criminals. Yonnie apart, none of Branson's associates bore any resemblance whatever to the popular concept of those who habitually stepped outside the law. Both men, in fact, had killed a number of times, but then only legally — as far as the term 'legal' could be interpreted- as members of a highly specialized Marine commando unit in Vietnam. Disillusioned with civilian life they'd found their next best panacea with Branson, who had a splendid eye for the recruitment of such men. They had not killed since. Branson approved of violence if and when necessary: killing was not permitted except as a last resort. In his thirteen years of upsetting law officers in the United States, Canada and Mexico, Branson had not yet had to have recourse to the last resort. Whether this was due to moral scruples or not was unclear: what was clear was that Branson regarded it as bad business. The degree of intensity of police efforts to catch robbers as opposed to murderers differed quite appreciably.
The windows of both front doors of the car were wound down — obviously they had been so at the moment of the crash. The four uniformed men seated inside had not been seriously injured but clearly had been badly shaken and had suffered minor damage, the worst of which appeared to be a broken nose sustained by the man in the front seat next to the driver. For the most part they were just dazed, too dazed, in any effect to offer any resistance to the removal of their weapons. Working in smooth unison Kowalski and Peters wound up the front windows. Peters closed his door while Kowalski threw in a gas bomb and closed his in turn.
None of any of this action had been witnessed by the returning police car's crew or the motor-cycle outriders. The policemen left their cars and machines and were cautiously approaching the lead coach when Yonnie and Van Effen with the five others came running up. All had guns of one kind or another in their hands.
'Quickly!' Van Effen shouted. 'Take cover! There are a couple of crazy bastards back in that coach there, one with a bazooka, the other with a Schmeisser. Get behind the bus!'
Given time to consider the matter the policemen might have queried Van Effen's statements but they weren't given the time and the instinct for immediate if irrational self-preservation remains always paramount. Van Effen checked quickly to see if they were hidden from the view of the Presidential coach. They were. Not that he feared anything from that source, he just wanted to be spared the chore of blasting open the lock of the door that would be surely locked against them if their actions were observed.
He nodded to Yonnie and walked away with another man towards the rear of the bus. Whatever might be said, and had unkindly been said, about Yoanie's cerebral limitations, this was the situation he had been born for, a basically elemental one in which action took precedence over thoughts. Long training had even given the vocabulary appropriate to the occasion. He said: 'Let's kinda put our hands up, huh?'
The six men turned round. Their expressions ran through the gamut of astonishment, anger and then resignation. Resignation was all that was left them. They had, with reason enough, not yet thought it time to produce their own weapons, and when the wise man is confronted at point-blank range with a pair of submachine-pistols he does what he is told and just kinda puts his hands up. Yonnie kept them covered while another man relieved them of their pistols. The remaining two men began to run back towards the rear coach as soon as they saw Van Effen and another climb aboard the Presidential coach.
The reaction of those aboard this coach had, so far, amounted to no more than an amalgam of perplexity and annoyance, and even that was slight enough. One or two were making the customary laborious effort to rise when Van Effen mounted the steps.
'Please relax, gentlemen,' he said. 'Just a slight delay.' Such is the authority of even a white coat in a street accident a crowd will make way for a man in a butcher's apron- that everybody subsided. Van Effen produced an unpleasant-looking weapon, a double-barrelled 12-bore shotgun with most of the barrel and stock removed to make for easier transport, if not accuracy. 'I am afraid this is what you might call a hold-up or hi-jack or kidnap. I don't suppose it matters very much what you call it. Just please remain where you are.'
'Good God in heaven!' The President stared at Van Effen's moonface as if he were a creature from outer space. His eyes, as if drawn magnetically, went to the King and the Prince, then he returned his incredulous, outraged gaze to Van Effen. 'Are you insane? Don't you know whom I am? Don't you know you're pointing a gun at the President of the United States?'
'I know. You can't help being what you are any more than I can help being what I am. As for pointing guns at Presidents, it's a long if not very honourable tradition in our country. Please do not give any trouble.' Van Effen looked directly at General Cartland — he'd had him under indirect observation from the moment he had entered the coach.
