I AM Legend

As he left the Science Room, he looked up at the clock over the door.

The red hands had stopped at four-twenty-seven. He wondered what day they had stopped. As he descended the stairs with his armful of books, he wondered at just what moment the clock had stopped. Had it been morning or night? Was it raining or shining? Was anyone there when it stopped?

He twisted his shoulders irritably. For God's sake, what's the difference? he asked himself. He was getting disgusted at this increasing nostalgic preoccupation with the past. It was a weakness, he knew, a weakness he could scarcely afford if he intended to go on. And yet he kept discovering himself drifting into extensive meditation on aspects of the past. It was almost more than he could control, and it was making him furious with himself.

He couldn't get the huge front doors open from the inside, either; they were too well locked. He had to go out through the broken window again, first dropping the books to the sidewalk one at a time, then himself. He took the books to his car and got in.

As he started the car, he saw that he was parked along a red-painted curb, facing in the wrong direction on a one-way street. He looked up and down the street.

"Policeman!" he found himself calling. "Oh, policeman!"

He laughed for a mile without stopping, wondering just what was so funny about it.

He put down the book. He'd been reading again about the lymphatic system. He vaguely remembered reading about it months before, during the time he now called his 'frenzied period'. But what he'd read had made no impression on him then because he'd had nothing to apply it to.

There seemed to be something there now.

The thin walls of the blood capillaries permitted blood plasma to escape into the tissue spaces along with the red and colorless cells. These escaped materials eventually returned to the blood system through the lymphatic vessels, carried back by the thin fluid called lymph.

During this return flow, the lymph trickled through lymph nodes, which interrupted the flow and filtered out the solid particles of body waste, thus preventing them from entering the blood system.

Now.

There were two things that activated the lymphatic system: (1) breathing, which caused the diaphragm to compress the abdominal contents, thus forcing blood and lymph up against gravity; (2) physical movement, which caused skeletal muscles to compress lymph vessels, thus moving the lymph. An intricate valve system prevented any backing up of the flow.

But the vampires didn't breathe; not the dead ones, anyway. That meant, roughly, that half of their lymph flow was cut off. This meant, further, that a considerable amount of waste products would be left in the vampire's system.

Robert Neville was thinking particularly of the fetid odor of the vampire.

He read on

"The bacteria passes into the blood stream, where..."

"--the white corpuscles playing a vital part in our defense against bacteria attack."

"Strong sunlight kills many germs rapidly and..."

"Many bacterial diseases of man can be disseminated by the mechanical agency of flies, mosquitoes..."

"--where, under the stimulus of bacterial attack, the phagocytic factories rush extra cells into the blood stream."

He let the book drop forward into his lap and it slipped off, his legs and thumped down on the rug.

It was getting harder and harder to fight, because no matter what he read, there was always the relationship between bacteria and blood affliction. Yet, all this time, he'd been letting contempt fall freely on all those in the past who had died proclaiming the truth of the germ theory and scoffing at vampires.

He got up and made himself a drink. But it sat untouched as he stood before the bar. Slowly, rhythmically, he thudded his right fist down on the top of the bar while his eyes stared bleakly at the wall.

Germs.

He grimaced. Well, for God's sake, he snapped jadedly at himself, the word hasn't got thorns, you know. He took a deep breath. All right, he ordered himself, is there any reason why it couldn't be germs?

He turned away from the bar as if he could leave the question there. But questions had no location; they could follow him around.

He sat in the kitchen staring into a steaming cup of coffee. Germs. Bacteria. Viruses. Vampires. Why am I so against it? he thought. Was it just reactionary stubbornness, or was it that the task would loom as too tremendous for him if it were germs?

He didn't know. He started out on a new course, the course of compromise. Why throw out either theory? One didn't necessarily negate the other. Dual acceptance and correlation, he thought.

Bacteria could be the answer to the vampire.

Everything seemed to flood over him then. It was as though he'd been the little Dutch boy with his finger in the dike, refusing to let the sea of reason in. There he'd been, crouching and content with his iron-bound theory. Now he'd straightened up and taken his finger out. The sea of answers was already beginning to wash in.

The plague had spread so quickly. Could it have done that if only vampires had spread it? Could their nightly marauding have propelled it on so quickly?

He felt himself jolted by the sudden answer. Only if you accepted bacteria could you explain the fantastic rapidity of the plague, the geometrical mounting of victims.

He shoved aside the coffee cup, his brain pulsing with a dozen different ideas. The flies and mosquitoes had been a part of it. Spreading the disease, causing it to race through the world.

Yes, bacteria explained a lot of things; the staying in by day, the coma enforced by the germ to protect itself from sun radiation.

A new idea: What if the bacteria were the strength of the true vampire? He felt a shudder run down his back. Was it possible that the same germ that killed the living provided the energy for the dead?

He had to know! He jumped up and almost ran out of the house. Then, at the last moment, he jerked back from the door with a nervous laugh. God's sake, he thought, am I going out of my mind? It was nighttime. He grinned and walked restlessly around the living room.

Could it explain the other things? The stake? His mind fell over itself trying to fit that into the framework of bacterial causation. Come on! he shouted impatiently in his mind. But all he could think of was hemorrhage, and that didn't explain that woman. And it wasn't the heart....He skipped it, afraid that his new-found theory would start to collapse before he'd established it.

The cross, then. No, bacteria couldn't explain that. The soil; no, that was no help. Running water, the mirror, garlic...He felt himself trembling without control and he wanted to cry out loudly to stop the runaway horse of his brain. He had to find something! Goddamn it! he raged in his mind. I won't let it go!

He made himself sit down. Trembling and rigid, he sat there and blanked his mind until calm took over. Good Lord, he thought finally, what's the matter with me? I get an idea, and when it doesn't explain everything in the first minute, I panic. I must be going crazy.

He took that drink now; he needed it. He held up his glass, it was shaking. All right, little boy, he tried kidding himself, calm down now. Santa Claus is coming to town with all the nice answers. No longer will you be a weird Robinson Crusoe, imprisoned on an island of night surrounded by oceans of death.

He snickered at that, and it relaxed him. Colorful, he thought, tasty. The last man in the world is Edgar Guest.

All right, then, he ordered himself, you're going to bed. You're not going to go flying off in twenty different directions. You can't take that any more; you're an emotional misfit.

The first step was to get a microscope. That is the first step, he kept repeating forcefully to himself as he undressed for bed, ignoring the tight ball of indecision in his stomach, the almost painful craving to plunge directly into investigation without any priming.

He almost felt ill, lying there in the darkness and planning just one step ahead. He knew it had to be that way, though. That is the first step, that is the first step. God?damn your bones, that is the first step.

He grinned in the darkness, feeling good about the definite work ahead.

One thought on the problem he allowed himself before sleeping. The bitings, the insects, the transmission from person to person--were even these enough to explain the horrible speed with which the plague spread?

He went to sleep with the question in his mind. And, about three n the morning, he woke up to find the house buffeted by another dust storm. And suddenly, in the flash of a second, he made the connection.

Chapter Eleven

THE FIRST ONE HE got was worthless.

The base was so poorly leveled that any vibration at all disturbed it. The action of its moving parts was loose to the point of wobbling. The mirror kept moving out of position because its pivots weren't tight enough. Moreover, the instrument had no substage to hold condenser or polar?izer. It had only one nosepiece, so that he had to remove the object lens when he wanted any variation in magnification. The lenses were impossible.
