statistically. I was assigned to determine the connection between one phenomenon and other phenomena. That’s all that science ever does, and all that it ever will do — until the end. Resurrection? By no means. Don’t be ridiculous. The term is used much too loosely. I’m not claiming that the corpses came back to life, with their hearts beating, their brains thinking, the coagulated blood in their veins flowing again. The changes which take place in a dead body are not reversible in that sense. What other sense is there, you ask — the corpses moved around, changed their positions in space. I agree, but the things you’re talking about are nothing but facts — I have explanations!”
Sciss moved closer to the map and raised his arm. No longer smiling, he spoke quickly and energetically, his high-pitched voice taking on a triumphant note.
“A phenomenon is subject to analysis only if the structure of its events, as in this case, conforms to a regular pattern. Science progresses by discovering the connection between one phenomenon and other phenomena, and this is exactly what I succeeded in doing. If I were to ask why a rock falls when dropped, you would reply that it is due to the action of gravity. Yet if I asked what gravity is, there would be no answer. But even though we don’t know what gravity is, we can determine its regular pattern of action. People become accustomed to rocks always falling. Any phenomenon which continues to exist within everyday comprehension, even if incomprehensible in itself, ends up being commonplace. For example, if human or animal corpses usually got up and walked around, if that was the norm, the police wouldn’t be interested in the incidents in Norfolk. I was assigned to determine the cause of this seemingly abnormal series of phenomena, and, its uniqueness notwithstanding, to connect it with some other series of phenomena that was already familiar, documented, and of such long standing that its occurrences no longer shock the public or arouse the curiosity of the police. Death by cancer is a perfect example of this kind of phenomenon. I examined parish registries from the whole Norfolk region as well as hospital death records for the past fifty years. Of course I encountered a certain amount of difficulty. During the early part of this fifty-year period doctors were not able to differentiate cancer, or to treat it as a separate disease as they do nowadays. However, to the extent that it was possible, I collected the facts regarding the number of cancer-related deaths, translated them into statistics, and transferred them to this map. You can see the results.”
Sciss turned off the light and went back to his desk, and as he did so Gregory finally discovered the source of the unpleasant odor: it was emanating from the corner just beyond the closet, where he could see some long, low boxes crammed with moldy, stained, old books.
“To make a long story short, Mr. Gregory, mortality due to cancer follows a regular cycle and is in turn governed by it. Around the end of the nineteenth century we begin to see an irregular but steady increase in incidences of cancer, and nowadays, as a result, more people than ever contract cancer and die from cancer. Norfolk and its surrounding region, however, constitutes an enclave with a relatively low cancer mortality. In other words, the rate of death from cancer has remained more or less the same for the past thirty years, although it has continued to increase in adjacent regions. When the difference between the mortality rates of this enclave and the adjacent localities exceeded a certain level, corpses began to disappear. The center, that is, the place where the first disappearance occurred, is not the geometric, spatial center of the enclave, but the place in which cancer mortality reached the lowest level. The phenomenon spread from that point in a definite pattern: it moved rapidly because of such factors as temperature, etc. As you should remember, I’ve already explained that. In the last incident, the phenomenon reached the boundaries of the enclave. The formula which I have derived from the statistics on cancer deaths excludes the possibility of any corpse disappearances outside the enclave. It was on this basis that I wrote to Sheppard.”
Sciss fell silent, turned around, and picked up the lamp. He held it in his hand for a moment, as if uncertain what to do with it, then placed it on his desk.
“You made up your mind on the basis of this?” Gregory whispered, warning himself to proceed cautiously.
“No. There was more.”
Sciss folded his arms across his chest.
“In the earlier incidents, the corpses disappeared, so to speak, ‘permanently’; that is, they were moved for an unknown distance in an unknown direction. In the last incident, however, there was comparatively little displacement of the corpse. Why? Because the last incident occurred very close to the boundary of the enclave. This helped me to define the coefficient of my formula with great precision, inasmuch as the rate of cancer mortality increases by an arithmetic rather than a geometric progression as we trace its passage from the enclave into the adjacent regions.”
The room was silent. Gregory could hear the far-off hissing of the gas burner.
“All right,” he said at last. “In your opinion, then, what caused the disappearances? The movements, if you prefer.”
Sciss smiled faintly, looking at the detective with an amused expression.
“I beg your pardon,” he said, “but I’ve already answered your questions. You’re acting like a child who is shown Maxwell’s theorem and a diagram of a radio receiver and then asks, ‘How does this box talk?’ It has never occurred to you or your Chief to institute an investigation against whatever causes people to contract cancer, has it? Similarly, at least as far as I know, you’ve never made inquiries about the perpetrator of Asiatic flu.”
Gregory clenched his teeth, warning himself not to respond to Sciss’s sarcasm.
“All right,” he said. “The way you see things you’re right. Since it’s only a simple case of resurrection, rather than a matter of corpses moving, standing, and walking after death, you consider everything to be perfectly clear- cut and understandable and therefore not worth any further investigation.”
“Do you think I’m an idiot?” Sciss said, sitting down on the radiator again. His voice was suprisingly gentle. “Obviously there’s a good deal here for biochemists, physiologists, and biologists to look into, but there’s nothing for the police. Futhermore, the study of something like this could go on and on without any definitive results, even after fifty years — just like the study of cancer. Only my field — statistics — can give immediate results. The same applies in the study of cancer. So far as this case is concerned, there will probably be quite a few conflicting theories in time, and I imagine that the ones the public finds most appealing will help to build up the circulation of the more sensational newspapers. The phenomenon will be connected with flying saucers, with astrology, with God only knows what. But all that is none of my business.”
“What about the dead animals we found at the scene of the disappearances?” Gregory asked, pretending not to have heard the note of anger that was beginning to appear in Sciss’s voice.
“That interests you? Yes, of course…” Sciss said. Suddenly calm again, he clasped his knees with his thin, twisted arms.
“I didn’t analyze that particular point mathematically, but the simplest and most fundamental explanation would be to regard the animal as a
“Is it some kind of bacteria?” Gregory asked. He was leaning against the open door of the closet, studying Sciss’s shadow on the floor in front of him but listening carefully.
“I didn’t say that. I don’t know. I don’t know a thing. The theory is full of holes.
“If it’s not a bacteria, but, as you say, a biological factor, maybe it’s a microbe,” Gregory said. “An intelligent microbe, in fact a very intelligent microbe, a microbe with the ability to think ahead the way a human being does.”
“I get the impression that you’re looking for a way to make a profit on this story — what are you planning, a magazine article about intelligent microbes?” Sciss’s voice shook with anger. Gregory, as if he hadn’t heard, walked slowly toward Sciss, very slowly, speaking more and more distinctly, yet faster and faster, as if he were being consumed by the fire of a brilliant idea.
“This factor,” Gregory said, “suddenly turns up in the middle of the area that has the low death rate. It carries out all its activities with as much foresight as a conscious being, except that at the beginning it’s still inexperienced. It doesn’t know, for instance, that most people would consider a naked corpse a little — let’s say —
