while they’re threatening each other with so many hundreds of megaton-carrying missiles, they are not really thinking of their missiles at all. They are thinking, gentlemen, of Mordon, for we—the British, I should say—have made it our business to ensure that the great nations understand exactly what is going on behind the fences of Mordon.” He tapped the brickwork beside him. “Behind this very wall here. The ultimate weapon. The world’s one certain guarantee of peace. The term ‘ultimate weapon’ has been used too freely, has come almost to lose its meaning. But the term, in this case, is precise and exact. If by ‘ultimate’ one means total annihilation.”
He smiled, a little self-consciously.
“I’m being melodramatic, a little? Perhaps. My Latin blood shall we say? But listen carefully, gentlemen, and try to understand the full significance of what I’m going to say. Not the General and Colonel, of course, they already know: but you, Superintendent, and you, Mr. Cavell.
“We have developed in Mordon here over forty different types of plague germs. I will confine myself to two. One of them is a derivative of the botulinus toxin—which we had developed in World War II. As a point of interest, a quarter of a million troops in England were inoculated against this toxin just before D-Day and I doubt whether any of them know to this day what they were inoculated against.
“We have refined this toxin into a fantastic and shocking weapon compared to which even the mightiest hydrogen bomb is a child’s toy. Six ounces of this toxin, gentlemen, distributed fairly evenly throughout the world, would destroy every man, woman and child alive on this planet today. No flight of fancy.” His voice was weighted with heavy emphasis, his face still and sombre. “This is simple fact. Give me an airplane and let me fly over London on a windless summer afternoon with no more than a gramme of botulinus toxin to scatter and by evening seven million Londoners would be dead. A thimbleful in its water reservoirs and London would become one vast charnel house. If God does not strike me down for using the term ‘ideal’ in this connection, then this is the ideal form of germ warfare. The botulinus toxin oxidises after twelve hours exposure to the atmosphere and becomes harmless. Twelve hours after country A releases a few grammes of botulinus over country B it can send its soldiers in without any fear of attack by either the toxin or the defending soldiers. For the defending soldiers would be dead. And the civilians, the men, the women, the children. They would all be dead. All dead.”
Gregori fumbled in his pocket for another cigarette. His hands were shaking and he made no attempt to conceal the fact. He was probably unaware of it.
I said, “But you used the term ‘ultimate weapon’, as if we alone possessed it. Surely the Russians and Americans——”
“They have it too. We know where Russia’s laboratories in the Urals are. We know where the Canadians manufacture it—the Canadians were leaders in the field until recently—and it’s no secret that there are four thousand scientists working on a crash programme in Fort Detrick in America to produce even more deadlier poisons, so hurried a crash programme that we know that scientists have died and eight hundred of them fallen ill over the past few years. They have all failed to produce this deadlier poison. Britain has succeeded which is why the eyes of the world are on Mordon.”
“Is it possible?” Hardanger’s tone was dry but his face was set. “A deadlier poison than this damn’ botulinus? Seems kind of superfluous to me.”
“Botulinus has its drawback,” Gregori said quietly. “From a military viewpoint that is. Botulinus you must breathe or swallow to become infected. It is not contagious. Also, we suspect that a few countries may have produced a form of vaccine against even the refined type of drug we have developed here. But there is no vaccine on earth to counteract the newest virus we have produced—and it’s as contagious as a bush-fire.
“This other virus is a derivative of the polio virus—infantile paralysis, if you will—but a virus the potency of which has been increased a million times by—well, the methods don’t matter and you wouldn’t understand. What does matter is this: unlike botulinus, this new polio virus is indestructible—extremes of heat and cold, oxidisation and poison have no effect upon it and its life span appears to be indefinite, although we believe it impossible—we hope it impossible—that any virus could live for more than a month in an environment completely hostile to growth and development; unlike botulinus it is highly contagious, as well as being fatal if swallowed or breathed; and, most terrible of all, we have been unable to discover a vaccine for it. I myself am convinced that we can never discover a vaccine against it.” He smiled without humour. “To this virus we have given a highly unscientific name, but one that describes it perfectly—the Satan Bug. It is the most terrible and terrifying weapon mankind has ever known or ever will know.”
“No vaccine?” Hardanger said. His tone wasn’t dry this time but his lips were. “No vaccine at all?”
“We have given up hope. Only a few days ago, as you will recall, Colonel Weybridge, Dr. Baxter thought he had found it—but we were completely wrong. There is no hope, none in the world. Now all our efforts are concentrated on evolving an attenuated strain with a limited life-span. In its present form, we obviously cannot use it. But when we do get a form with a limited life-span—and its death must be caused by oxidisation—then we have the ultimate weapon. When that day comes all the nations of the world may as well destroy their nuclear weapons. From a nuclear attack, no matter how intense, there will always be survivors. The Americans have calculated that even a full-scale Soviet nuclear attack on their country, with all the resources at Russia’s disposal, would cause no more than seventy million deaths—no more, I say!—with possibly several million others as a result of radiation. But half the nation would survive, and in a generation or two that nation would rise again. But a nation attacked by the Satan Bug would never rise again: for there would be no survivors.”
I hadn’t been wrong about Hardanger’s lips being dry, he was licking them to make speaking easier. Someone should see this, I thought. Hardanger scared. Hardanger truly and genuinely frightened. The penitentiaries of Britain were full of people who would never have believed it.
“And until then,” Hardanger said quietly. “Until you have evolved this limited life-strain?”
“Until then?” Gregori stared down at the concrete floor. “Until then? Let me put it this way. In its final form the Satan Bug is an extremely refined powder. I take a salt-spoon of this powder, go outside in the grounds of Mordon and turn the salt-spoon upside down. What happens? Every person in Mordon would be dead within an hour, the whole of Wiltshire would be an open tomb by dawn. In a week, ten days, all life would have ceased to exist in Britain. I mean all life. The Plague, the Black Death—was nothing compared with this. Long before the last man died in agony ships or planes or birds or just the waters of the North Sea would have carried the Satan Bug to Europe. We can conceive of no obstacle that can stop its eventual world-wide spread. Two months I would say, two months at the very most.
“Think of it, Superintendent, think of it. If you can, that is, for it is something really beyond our conception, beyond human imagination. The Lapp trapping in the far north of Sweden. The Chinese peasant tilling his rice-fields in the Yangtse valley. The cattle rancher on his station in the Australian outback, the shopper in Fifth Avenue, the primitive in Tierra del Fuego. Dead. All dead. Because I turned a salt-spoon upside down. Nothing, nothing, nothing can stop the Satan Bug. Eventually all forms of life will perish. Who, what will be the last to go? I cannot say. Perhaps the great albatross for ever winging its way round the bottom of the world. Perhaps a handful of Eskimos deep in the Arctic basin. But the seas travel the world over, and so also do the winds: one day, one day soon, they too would die.”
By this time I felt like lighting a cigarette myself and I did. If any enterprising company had got around to running a passenger rocket service to the moon by the time the Satan Bug got loose, they wouldn’t have to spend all that much on advertising.
“What I’m afraid of you see,” Gregori went on quietly, “is what we may find behind that door. I have not the mind of a detective, but I can see things when they lie plainly before me. Whoever broke his way into Mordon was a desperate man playing for desperate stakes. The end
