gone off the rails never talk about it, for the simple reason that they are unshakably convinced that their minds are still on the track. He said carefully, 'I don't think I understand.'
'You don't. But you will.' I said to the General: 'You must persuade the Cabinet to go on with this evacuation of the Central London area. Continuous radio and TV broadcasts. They'll have no difficulty in persuading the people to leave, you can believe that. It shouldn't cause much trouble — that area's pretty well unlived in by night, anyway.' I turned again to Hardanger. 'Have two hundred of your best men armed. A gun for me, too — and a knife. I know exactly what Gregori intends to do to-night. I know exactly what he hopes to achieve. I know exactly how he intends to leave the country — and exactly where he will be leaving from.'
'How do you know, my boy?' The General's voice was so quiet that I could hardly hear above the drumming of the rain.
'Because Gregori talked too much. Sooner or later they all talk too much. Gregori was cagier than most, even when he was convinced that we would all be dead in a minute he still said very little. But that little was too much. And I think I've really known ever since we found MacDonald's body.'
'You must have heard things that I didn't hear,' Hardanger said sourly.
'You heard it all. You heard him say he was going to London, if he really wanted the bug set loose in London to have Mordon destroyed he'd have stayed in Mordon to see what happened and have had some stooge do the job in London. But he has no interest in seeing Mordon destroyed, he never had. There's something he has to do in London. Another of his never-ending red herrings — the Communist red herring, of course, was purely fortuitous, he'd no hand in that at all. That's the first thing. The second — that he was going to achieve some great ambition
'Suppose you tell us,' Hardanger said impatiently.
So I told them.
The rain still fell as vertically, as heavily as ever, just as heavily as when we had left that farmhouse some hours previously, where the torrential rain in conjunction with the quick evacuation of the area had robbed the botulinus toxin of all victims other than the unfortunate policeman who had died so terribly before our eyes. Now, at twenty minutes past three in the morning, the rain was ice-cold, but I didn't really feel it. All I could feel was my exhaustion, the harsh stabbing pain in my right ribs that came with every breath I took and the continuous rending worry that, in spite of the confidence I'd shown to the General and Hardanger, I might be hopelessly wrong after all and Mary lost to me for ever. And even if I were right, she might still as easily be lost to me. With a conscious and almost desperate effort of will, I turned my mind to other things.
The high-walled courtyard where I'd been standing for the past three hours was dark and deserted, as dark and deserted as the heart of London itself. Evacuation of the centre of the city, the temporarily homeless going to prepared halls, ballrooms and theatres, had begun shortly after six o'clock, just after the last of the offices, businesses and shops had closed: it had been hastened by radio broadcasts at nine o'clock saying that, according to the latest message received, the time for the release of the botulinus toxin had been advanced from four a.m. to half past two: but there had been no hurry, no panic, no despair, in fact there would have been no sense of anything unusual happening had it not been for the unusual number of people carrying suitcases: the phlegmatic Londoners who had seen the City set on fire and suffered a hundred nights of mass area bombing during the war weren't to be stampeded into anything for anybody.
Between half past nine and ten o'clock over a thousand troops had combed their methodical way through the heart of the city checking that every last man, woman and child had been moved to safety, that no one had been inadvertently overlooked. At half past eleven a darkened drifting police launch had nosed silently into the north bank of the river and put me ashore on the Embankment, just below Hungerford Bridge. At midnight troops and police, all of them armed, had completely sealed off the entire area, including the bridges across the Thames. At one o'clock a power failure on a large scale had blacked out the better part of a square mile of the city — the square mile cordoned off by troops and police.
Twenty past three. Fifty minutes after the timed release of the botulinus toxin. It was time to go. I eased the borrowed Webley in its ill-fitting holster, checked the knife that was strapped, handle downwards, to my left forearm, and moved out into the darkness.
I'd never seen a picture of, far less visited, the new helicopter port on the North Bank, but an Inspector of the Metropolitan Police had briefed me so exhaustively that by the time he had finished I could have found my way up there blind-folded. And that, to all intents and purposes, was exactly what I was. Blind-folded. Blind. In that blacked-out city and oh that weeping overcast night, the darkness was just one degree short of absolute.
I had been told that there were three different ways up to the heliport, perched on the roof of the station, a hundred feet above the streets of London. There were two lifts, but with the power failure those would be out of operation. Between those lifts was a glassed-in circular staircase without a shred of cover from top to bottom, using which would be as neat a way as any of committing suicide if there was a reception committee waiting and I could not see Gregori as a man who would leave his main line of approach unguarded. And then there was the third way, the fire-escape on the other side of the station. That was the only way in for me.
I walked two hundred yards from the courtyard along a narrow cobbled lane. When the wall gave way to a high wooden fence I reached for the top, pulled myself up, slipped quietly down on the other side and set off along the railway tracks.
The reference book compilers who assert that Capham Junction has more sets of parallel tracks than any place in Britain wouldn't go around making silly statements like that if they'd tried this lot on a pitch black October night with the sleety rain falling about their ears. There wasn't a single piece of ironware in the whole interminable width of those tracks that I didn't find that night, usually with my ankles and shins. Railway lines, wires, signalling gear, switch gear, hydrants, platforms where there shouldn't have been platforms — I found them all. To add to my discomfort the burnt cork that had been so heavily rubbed into my face and hands was beginning to run, and burnt cork tastes exactly as you would expect it to taste: and when it gets in your eyes it hurts. The only hazard I didn't have to contend with was live rails— the power had been switched off.
I found the fence on the other side of the track easily enough, just by walking into it. Once down in the lane on the other side I turned left and made my way towards the fire-escape which came down, I had been told, into a small recessed court. I found the court, crossed the entrance and flattened myself against the far wall. The fire- escape was there all right, just barely discernible twenty feet away against the fractionally lighter darkness of the sky, gaunt and stark and angular and zig-zagging upwards out of sight. The first two or three flights of the fire- escape were invisible, lost against the darkness of high walls beyond.
For three minutes I stood there, showing as many signs of life as a wooden Indian. Then I heard it — even above the drumming of the sleet on my sodden shoulders and the sound of water running in the gutters, I heard it: the slight shuffle of a shoe on the pavement as someone changed his cramped position. The sound didn't come again, but then I didn't need to hear it again. Once was enough. Someone was standing directly under the lowermost platform of the fire-escape and if he turned out to be the soul of innocence doing it for his health's sake it would be surprising, to say the least. It was also going to be unfortunate for him, but he wouldn't be caring much when he was dead.
Finding this man here didn't give me any feeling of dismay and frustration because of the possible threat and setback he offered, all it afforded me was the sense of profound satisfaction and relief that could not be described. I had gambled, but I had won. Dr. Gregori was doing exactly what I'd told the General and Hardanger he would be doing.
The knife came free of its sheath and I brushed the blade with the ball of my thumb. It had a point like a lancet and an edge like a scalpel. It was only a very little knife, but three and a half inches of steel can kill you just as dead as the longest stiletto or the heaviest broadsword. If you know where to hit, that is. I had a fair idea where to hit, and how. And at anything up to ten paces I was twice as accurate with a knife as with a gun.
I covered sixteen of the intervening twenty feet in just over ten seconds, making no more sound than the
