area.’ ‘And beyond that?’ de Graaf said.
‘Nothing. We have no leads.’
De Graaf nodded and looked down at the paper he held in his hands. ‘That message from the mysterious FFF. No indication whatsoever as to the reason behind this threatened — now actual — sabotage. just a warning that nobody should be at ground level at i x a.m. this morning and that all planes should be flown out yesterday afternoon or evening to adjacent airfields as the needless destruction of property formed no part of their plans. Very considerate of them, I must say. And even more considerate, Jon, was the phone call you got at nine o’clock this morning urging you to evacuate all those planes immediately. But, of course, we all knew it was a hoax, so we paid no attention. Would you recognize that voice again, Jon?’
‘Not a chance-. It was a woman’s voice, a young woman and speaking in English. All young women speaking English sound the same to me.’ Fist clenched, de Jong gently thumped the table before him. ‘They don’t even hint at the reason for carrying out this — this monstrous action. What have they achieved by this action? Nothing. Absolutely nothing. I repeat that any person or persons who behave in this fashion have to be mentally unbalanced.’
Van Effen said: ‘I’m sorry, sir, I disagree. I do agree with what the Colonel said on the roof — they’re almost certainly as sane as any one. No one who is mentally unbalanced could have carried out this operation. And they’re not, as I said, wild-eyed terrorists throwing bombs in crowded market-places. In two separate warnings they did their best to ensure that neither human lives nor property would be put at risk. That was not the behaviour of irresponsible people.’
‘And who, then, was responsible for the deaths of the three people who lost their lives when that Fokker Friendship cartwheeled and crashed on take-off?’
‘The saboteurs, indirectly. One could equally well say that you were, also indirectly. It might be argued you might at least have considered the possibility that the threat was not a hoax, taken even the most remote possibility into account and refused permission for the Fokker to take off at exactly i i a.m. But that permission was given, personally I understand, by you. It is as certain as certain can be that the saboteurs had carefully checked landing and take-off schedules and made sure that there were no planes either taking off or landing at or near that time. That Fokker was the private plane of a German industrialist and was therefore not listed on the scheduled departures. I suggest, Mr de Jong, that it’s futile to ascribe the blame for those three deaths to anyone. Sheer bad luck, an unfortunate coincidence in timing, an act of God, call it what you like. There was nothing planned, nothing calculated, no motive behind those deaths. It was nobody’s fault.’ De Jong had substituted finger-drumming for table thumping. ‘If those evil men were as considerate as you say, why didn’t they postpone the explosion when they saw people boarding the plane?’ ‘Because we don’t know that they were in a position to see anything and, even if they were, they were almost certainly unable to do anything about it. Had the explosives been activated by a radio-controlled device, sure, they could have stopped it. But, as I told you, I’m pretty certain it was an electrical timer and to deactivate that they would have had to assemble a boat, scuba gear and diver — and all in broad daylight — in a matter of minutes. In the time available, that would have been impossible.’ There was a faint but unmistakable sheen of sweat on de Jong’s forehead. ‘They could have phoned a warning.’
Van Effen looked at de Jong for a long moment, then said: ‘How much attention did you pay to the previous warning this morning?’ De Jong made no reply.
‘And you’ve just said that the saboteurs have achieved nothing, absolutely nothing, by their action. I know you’re upset, sir, and it seems unfair to press the point, but can you really be so naive as to believe that? They’ve already made a considerable achievement. They have achieved the beginnings of a climate of fear and uncertainty, a climate that can only worsen with the passing of the hours. If they’ve struck once, apparently without a blind bit of motivation, are the chances not high that they win strike again? If they do, when? If they do, where? And, above 0, there’s the why. What overpowering reason do they have to behave as they do?’He looked at de Graaf. ‘Soften up the victim but keep him in suspense as to your purpose in behaving in this fashion. It’s a novel form of blackmail and I see no reason why it shouldn’t work. I have the strong feeling that we are going to hear from the FFF in the very near future. Not to state the reasons for acting as they do, certainly not to make any specific demands. Dear me, no. Not that. That’s not the way you conduct psychological warfare. One turns the wheel that stretches the rack very, very slowly over a calculated period of time. Gives the victim time to ponder more deeply about the hopelessness of his situation while his morale sinks lower and lower. At least that’s how I believe they operated in the Middle Ages — when using the actual instrument, of course.’ De Jong said sourly: ‘You seem to know a lot about the workings of the criminal mind.’
‘A little.’ van Effen smiled agreeably. ‘I wouldn’t presume to tell you how to run an airport.’
‘And what am I to understand from that?’
‘Mr van Effen just means that a cobbler should stick to his last.’ De Graaf made a placatory gesture with his hand. ‘He’s the author of the now established text-book on the psychology of the criminal mind. Never read it myself. So, Peter. You seem sure the FFF will contact us very soon, but not to tell us about themselves or their objectives. Tell us what? The where and the when their next — ah — demonstration?’ ‘What else?’
A profound and rather gloomy silence was ended by the entrance of a waiter who approached. de Jong. ‘Telephone, sir. Is there a Lieutenant van Effen here?’
‘Me.’ Van Effen followed the waiter from the canteen and returned within a minute and addressed himself to de Graaf.
‘Duty sergeant. Apparently two men reported their boats missing some hours ago. Pleasure boat owners. The sergeant who took their complaint didn’t think it necessary to notify our department. Quite right, of course. The boats have now been recovered. One, it would seem, was taken by force. The boats are in our hands. I told them to take a couple of finger-print men aboard, return the boats to the owners but not to allow the owners aboard. If you can spare the time, sir, we can interview the two owners after we leave here: they live less than a kilometre from here.’
‘A promising lead, yes?’
‘No.’
‘I don’t think so either. However, no stone unturned. We may as well go now and — ‘
He broke off as the same waiter reappeared and approached him. ‘Phone again. For you this time, Colonel.’
De Graaf returned in a matter of seconds. ‘Jon, have you such a thing as a shorthand typist?’
‘Of course. Jan?’
‘Sir?’ A blond youngster was on his feet.
‘You heard the Colonel?’
‘Yes, sir.’ He looked at de Graaf. ‘What shall I say?’ ‘Ask her to take that phone call and type it out for me. Peter, you have clairvoyance, the second sight.’
‘The FFF?’
‘Indeed. The press, I need hardly say. The FFF have their publicity priorities right. Usual anonymous phone call. The sub-editor who took the call was smart enough to tape-record it but I’d be surprised if that is of the slightest help. A fairly lengthy statement, I understand. Shorthand is not my forte. Let us possess our souls in patience.’ They had possessed their souls for not more than four minutes when a girl entered and handed a type- written sheet to de Graaf. He thanked her, looked briefly at the sheet and said: ‘Action this day would appear to be their motto. This, I understand, is their statement in full and a fairly arrogant example of its kind it is, too. This is what the FFF says:
“‘Next time, perhaps, the responsible citizens in Amsterdam will listen to what we say, believe what we say and act accordingly. It is because you did not believe what we said that a misadventure occurred today. For this misadventure we hold Mr de Jong entirely responsible. He was given due warning and chose to ignore that warning. We deplore the unnecessary deaths of the three passengers aboard the Fokker Friendship but disclaim all responsibility. It was not possible for us to arrest the explosion.”’ De Graaf paused and looked at van Effen. ‘Interesting?’
‘Very. So they had an observer. We’ll never find him. He could have been in the airport but hundreds of people who don’t work here visit here every day. For all we know, there could have been someone outside the airport with a pair of binoculars. But that’s not what is interesting. The four first-aid men who brought in the most seriously injured passengers did not know at the time whether the three men who were later pronounced dead were, in fact, dead or alive. Two of them, I understand, died after admission, but none was officially pronounced dead until the
