IN THE MORNING WHEN he went outside he found that the milk and hamburger were gone.

His eyes rushed over the lawn. There were two women crumpled on the grass but the dog wasn't there. A breath of relief passed his lips. Thank God for that, he thought. Then he grinned to himself. If I were religious now, he thought, I'd find in this a vindication of my prayer.

Immediately afterward he began berating himself for not being awake when the dog had come. It must have been after dawn, when the streets were safe. The dog must have evolved a system to have lived so long. But he should have been awake to watch.

He consoled himself with the hope that he was winning the dog over, if only with food. He was briefly worried by the idea that the vampires had taken the food, and not the dog. But a quick check ended that fear. The hamburger had not been lifted over the garlic ring, but dragged through it along the cement of the porch. And all around the bowl were tiny milk splashes, still moist, that could have been made only by a dog's lapping tongue.

Before he had breakfast he put out more milk and more hamburger, placing them in the shade so the milk wouldn't get too warm. After a moment's deliberation he also put out a bowl of cold water.

Then, after eating, he took the two women to the fire and, returning, stopped at a market and picked up two dozen cans of the best dog food as well as boxes of dog biscuit, dog candy, dog soap, flea powder, and a wire brush.

Lord, you'd think I was having a baby or something, he thought as he struggled back to the car with his arms full. A grin faltered on his lips. Why pretend? he thought. I'm more excited than I've been in a year. The eagerness he'd felt upon seeing the germ in his microscope was nothing compared with what he felt about the dog.

He drove home at eighty miles an hour, and he couldn't help a groan of disappointment when he saw that the meat and drink were untouched. Well, what the hell do you expect? he asked himself sarcastically. The dog can't eat every hour on the hour.

Putting down the dog food and equipment on the kitchen table, he looked at his watch. Ten-fifteen. The dog would be back when it got hungry again. Patience, he told himself. Get yourself at least one virtue, anyway.

He put away the cans and boxes. Then he checked the outside of the house and the hothouse. There was a loose board to fasten and a pane to repair on the hothouse roof.

While he collected garlic bulbs, he wondered once again why the vampires had never set fire to his house. It seemed such an obvious tactic. Was it possible they were afraid of matches? Or was it that they were just too stupid? After all, their brains could not be so fully operative as they had been before. The change from life to mobile death must have involved some tissue deterioration.

No, that theory wasn't any good, because there were living ones around his house at night too. Nothing was wrong with their brains, was there?

He skipped it. He was in no mood for problems. He spent the rest of the morning preparing and hanging garlic strands. Once he wondered about the fact that garlic bulbs worked. In legend it was always the blossoms of the garlic plant He shrugged. What was the difference? The proof of the garlic was in its chasing ability. He imagined that the blossoms would work too.

After lunch he sat at the peephole looking out at the bowls and the plate. There was no sound anywhere except for the almost inaudible humming of the air-conditioning units in the bedroom, bathroom, and kitchen.

The dog came at four. Neville had almost fallen into a doze as he sat there before the peephole. Then his eyes blinked and focused as the dog came hobbling slowly across the street, looking at the house with white-rimmed, cautious eyes. He wondered what was wrong with the dog's paw. He wanted very much to fix it and get the dog's affection. Shades of Androcles, he thought in the gloom of his house.

He forced himself to sit still and watch. It was incredible, the feeling of warmth and normality it gave him to see the dog slurping up the milk and eating the hamburger, its jaws snapping and popping with relish. He sat there with a gentle smile on his face, a smile he wasn't conscious of. It was such a nice dog.

His throat swallowed convulsively as the dog finished eating and started away from the porch. Jumping up from the stool, he moved quickly for the front door.

Then he held himself back. No, that wasn't the way, he decided reluctantly. You'll just scare him if you go out. Let him go now, let him go.

He went back to the peephole and watched the dog wobbling across the street and moving in between those two houses again. He felt a tightness in his throat as he watched it leave. It's all right, he soothed himself, he'll be back.

He turned away from the peephole and made himself a mild drink. Sitting in the chair and sipping slowly, he wondered where the dog went at night. At first he'd been worried about not having it in the house with him. But then he'd realized that the dog must be a master at hiding itself to have lasted so long.

It was probably, he thought, one of those freak accidents that followed no percentage law. Somehow, by luck, by coincidence, maybe by a little skill, that one dog had survived the plague and the grisly victims of the plague.

That started him thinking. If a dog, with its limited intelligence, could manage to subsist through it all, wouldn't a person with a reasoning brain have that much more chance for survival?

He made himself think about something else. It was dangerous to hope. That was a truism he had long accepted.

The next morning the dog came again. This time Robert Neville opened the front door and went out. The dog immediately bolted away from the dish and bowls, right ear flattened back, legs scrambling frantically across the street.

Neville twitched with the repressed instinct to pursue.

As casually as he could manage, he sat down on the edge of the porch.

Across the street the dog ran between the houses again and disappeared. After fifteen minutes of sitting, Neville went in again.

After a small breakfast he put out more food.

The dog came at four and Neville went out again, this time making sure that the dog was finished eating.

Once more the dog fled. But this time, seeing that it was not pursued, it stopped across the street and looked back for a moment.

"It's all right, boy," Neville called but, but at the sound of his voice the dog ran away again.

Neville sat on the porch stiffly, teeth gritted with impatience. Goddamn it, what's the matter with him? he thought. The damn mutt!

He forced himself to think of what the dog must have gone through. The endless nights of groveling in the blackness, hidden God knew where, its gaunt chest laboring in the night while all around its shivering form the vampires walked. The foraging for food and water, the struggle for life in a world without masters, housed in a body that man had made dependent on himself.

Poor little fella, he thought, I'll be good to you when you come and live with me.

Maybe, the thought came then, a dog had more chance of survival than a human. Dogs were smaller, they could hide in places the vampires couldn't go. They could probably sense the alien nature of those about them, probably smell it.

That didn't make him any happier. For always, in spite of reason, he had clung to the hope that someday he would find someone like himself—a man, a woman, a child, it didn't matter. Sex was fast losing its meaning without the endless prodding of mass hypnosis. Loneliness he still felt.

Sometimes he had indulged in daydreams about finding someone. More often, though, he had tried to adjust to what he sincerely believed was the inevitable—that he was actually the only one left in the world. At least in as much of the world as he could ever hope to know.

Thinking about it, he almost forgot that nightfall was approaching.

With a start he looked up and saw Ben Cortman running at him from across the street.

"Neville!"

He jumped up from the porch and ran into the house, locking and bolting the door behind him with shaking hands.

For a certain period he went out on the porch just as the dog had finished eating. Every time he went out the dog ran away, but as the days passed it ran with decreasing speed, and soon it was stopping halfway across the street to look back and bark at him. Neville never followed, but sat down on the porch and watched. It was a game they played.

Then one day Neville sat on the porch before the dog came. And, when it appeared across the street, he remained seated.

For about fifteen minutes the dog hovered near the curb suspiciously, unwilling to approach the food. Neville edged as far away from the food as he could in order to encourage the dog. Unthinking, he crossed his legs, and the dog shrank away at the unexpected motion. Neville held himself quietly then and the dog kept moving around restlessly in the street, its eyes moving from Neville to the food and back again.

"Come on, boy," Neville said to it. "Eat your food, that's a good dog."

Another ten minutes passed. The dog was now on the lawn, moving in concentric arcs that became shorter and shorter.

The dog stopped. Then slowly, very slowly, one paw at a time, it began moving up on the dish and bowls, its eyes never leaving Neville for a second.

"That's the boy," Neville said quietly.

This time the dog didn't flinch or back away at the sound of his voice. Still Neville made sure he sat motionless so that no abrupt movement would startle the dog.

The dog moved yet closer, stalking the plate, its body tense and waiting for the least motion from Neville.

"That's right," Neville told the dog.

Suddenly the dog darted in and grabbed the meat. Neville's pleased laughter followed its frantically erratic wobble across the street.

"You little son of a gun," he said appreciatively.

Then he sat and watched the dog as it ate. It crouched down on a yellow lawn across the street, its eyes on Neville while it wolfed down the hamburger. Enjoy it, he thought, watching the dog. From now on you get dog food. I can't afford to let you have any more fresh meat.

When the dog had finished it straightened up and came across the street again, a little less hesitantly. Neville still sat there, feeling his heart thud nervously. The dog was beginning to trust him, and somehow it made him tremble. He sat there, his eyes fastened on the dog.

"That's tight, boy," he heard himself saying aloud. "Get your water now, that's a good dog."

A sudden smile of delight raised his lips as he saw the dog's good ear stand up. He's listening! he thought excitedly. He hears what I say, the little son of a gun!

"Come on, boy." He went on talking eagerly. "Get your water and your milk now, that's a good boy. I won't hurt you. Atta boy."

The dog went to the water and drank gingerly, its head lifting with sudden jerks to watch him, then dipping down again.

"I'm not doing anything," Neville told the dog.

He couldn't get over how odd his voice sounded. When a man didn't hear the sound of his own voice for almost a year, it sounded very strange to him. A year was a long time to live in silence. When you come live with me, he thought, I'll talk your ear off. The dog finished the water.

"Come `ere, boy." Neville said invitingly, patting his leg. "Come on."

The dog looked at him curiously, its good ear twitching again. Those eyes, Neville thought. What a world of feeling in those eyes! Distrust, fear, hope, loneliness—all etched in those big brown eyes. Poor little guy.

"Come on, boy, I won't hurt you," he said gently.

Then he stood up and the dog ran away. Neville stood there looking at the fleeing dog shaking his head slowly.

More days passed. Each day Neville sat on the porch while the dog ate, and before long the dog approached the dish and bowls without hesitation, almost boldly, with the assurance of the dog that knows its human conquest.

And all the time Neville would talk to it.

"That's a good boy. Eat up the food. That's good food, isn't it? Sure it is. I'm your friend. I gave you that food. Eat it up, boy, that's right. That's a good dog," endlessly cajoling, praising, pouring soft words into the dog's frightened mind as it ate.

And every day he sat a little bit closer to it, until the day came when he could have reached out ............
