Once again Mikhail Simonov was drawn back to the present, this time by the low rumble of diesel-engined transports that echoed up hollowly from the gorge to drown out the wind's thin keening. Just as the moon slipped back behind the clouds, so the headlight beams of a convoy of lumbering trucks cut a swath of white light in the darkness where they stabbed out from the gash of the pass in the deep 'V of the western saddle. The huge, square-looking trucks were just under a mile away across the ravine and some five hundred feet below the level of Simonov's vantage point, but still he flattened himself more yet and squirmed back a little into his nest of gaunt boulders. It was a controlled, automatic, almost instinctive reaction to possible danger, in no way a panicked retreat. Simonov had been very well trained, with no expense spared.
As the convoy came through the pass and turned its nose down the steeply descending ramp of a road cut from the face of the ravine, so a battery of spotlights burst into brilliant life, shining down from the sheer wall and lending the well-gritted road excellent illumination. Fascinated, Simonov listened to the great diesels snarling into low gear, watched the routine of a well-organized reception.
Without taking the nite-lites from his eyes, he reached into a pocket and drew out a tiny camera, snapping it into position in the lower casing of the binoculars. Then he pressed a button on the camera and continued watching. Whatever he saw would now be recorded automatically, one frame every six seconds for a total of four and a half minutes, forty-five tiny stills of near-crystal clarity. Not that he expected to see anything of any real importance: he already knew what the trucks contained and the camera shots were simply to certify that this was indeed their destination — for the satisfaction of others back in the West.
Four trucks: one of them containing all the makings of a ten-foot electrified fence, two more carrying the component parts and ammo for three twin-mounted, armour-piercing, 13mm Katushev cannons, and the fourth and last loaded with a battery of diesel-powered generators. No, what was being hauled wasn't the question. The question was this: if the Russians were going to defend the Perchorsk Projekt, who were they defending it against?
Who… or what?
Simonov's camera clicked away almost inaudibly; his eyes took in all that was happening below; he was aware that he mustn't stay here more than another ten or fifteen minutes at the most, because of the high radiation count, but part of his mind was already somewhere else. It was back in London just two months short of two years ago. Shooting the arrival of the trucks had done it, set Simonov's mind working on that other film he'd been shown by M16 and the Americans in London. A real film, however short, and not just stills. He relaxed just a traction. He was doing all that was expected of him, could afford a little mental meandering. And actually, once you'd seen that film, it was difficult not to keep going back to it.
The film was of something that had happened just seven weeks after the Perchorsk Incident (called 'pi') and had earned itself the acronym 'pi II' or 'Pill'. But it had been one hell of a pill to swallow. It had come about like this.
… Early morning of a bright mid-October day along the eastern seaboard of the USA; but along the 'obsolete' Canadian DEW-line things have been stirring for some three hours, since a pair of spysats with overlapping windows on the Barents and Kara seas, and from Arkhan-gel'sk across the Urals to Igarka, flashed intruder reports down across the Pole to listeners in Canada and the USAF bases in Maine and New Hampshire. Washington has been informed, and low-key alert status has already been notified to the missile bases in Greenland and the Foxe Peninsula base on Baffin Island. Other DEW-line subscribers have been notified; Great Britain has shown mild interest and asked for updates, Denmark is typically nervous (because of Greenland), Iceland has shrugged and France has failed to acknowledge.
But now things begin to speed up a little. The original spies-in-the-sky have lost the intruder (an 'intruder' being any aerial object passing east to west across the Arctic Ocean) out of their windows, but at the same time it's been picked up by DEW-line proper crossing the Arctic Circle on a somewhat irregular course but generally in the direction of Queen Elizabeth Island. What's more, the Russians have scrambled a pair of Mig interceptors from their military airfield in Kirovsk south of Murmansk. Norway and Sweden join Denmark in an attack of the jitters. The USA is hugely curious but not yet narrow-eyed (the object is too slow to be a serious threat) but nevertheless an AWACS reconnaissance aircraft has been diverted from routine duties to a line of interception and two fighters are scrambled up from a strip near Fort Fairfield, Maine.
It is now four hours since the — UFO? — was first sighted over Novaya Zemlya, and so far it has covered a little more than nine hundred miles, having passed west of Franz Josef Land on what now seems a beeline for Ellesmere Island. Which is where the Migs draw level with it, except that doesn't quite show the whole picture. Geographically they've caught up with it, but they're at max. headroom and the UFO is two miles higher! Then… apparently they see it — and at the same time it sees them.
What happens then isn't known for a certainty, for the Kirovsk base has ordered radio silence, but on the basis of what will be seen to happen later we can take a broad stab at it. The object descends, puts on speed, attacks! The Migs probably open fire on it in the seconds before they are reduced to so much confetti. Their debris is lost in snow and ice some six hundred miles from the Pole and a like distance short of Ellesmere…
And now the intruder really is intruding! Its speed has accelerated to around three hundred and fifty miles per hour and its course is straight as an arrow. The AWACS has reported the Migs lost from its screens, presumed down, but a hotline call from Washington to Moscow fails to produce anything but the usual ambiguities: 'What Migs? What intruder?'
The USA is a little peeved: This aircraft came out of your airspace into ours. It has no right being there. If it sticks to its present course it will be intercepted, forced to land. If it fails to comply or acts in any way hostile, there's a chance it will be shot down, destroyed…'
And unexpectedly: 'Good!' from the Russians. 'Whatever it is you have on your screens, it is nothing of ours. We renounce it utterly. Do with it as you see fit!'
Far more detailed Norwegian reports are now in from the Hammerfest listening station: the object is believed to originate from a region in the Urals near Labytnangi right on the Arctic Circle, give or take a hundred miles or so. If they had given or taken three hundred miles south, then the reports would have been more nearly correct; for the Perchorsk Pass was just that far away from the source they'd quoted. Alas, in the other direction, north of Labytnangi, lay Vorkuta, the USSR's most northerly missile site, supplied by rail from Ukhta. And now the Americans go from mildly irritated to extremely narrow-eyed. Just what in hell are the Reds up to? Have they loosed some sort of experimental missile from Vorkuta and lost it? If so, does it have a warhead?
How many warheads?
Alert classifications go up two notches and Moscow comes under fire in some very heated hotline exchanges. Still the Soviets deny all knowledge, however nervously.
Better, clearer reports are coming in. We now have the thing on satellite, on ground radar, on AWACS. No physical, human sightings as yet but everything else. The spysats say it could be a dense flock of birds — but what sort of birds fly in excess of three hundred mph five miles high across the Arctic Circle? Collision with birds could have taken out the Migs, of course, but… The top-secret high-tech radar sites along the older DEW-line say it's either a large airplane or… a space-platform fallen out of orbit? Also that it's impossibly low on metal content — namely, it doesn't have any! But intelligence won't admit of any aircraft (not to mention space-stations) two hundred and some feet long and constructed of canvas. AWACS says that the thing is flying in a series of spurts or jets, like some vast aerial octopus. And AWACS is more or less right.
