But now it’s different. I know now that you were just as much forced into your situation as we were forced into ours. We are infected. But you already know that. What you don’t understand yet is that we’re going to stay alive. We’ve found a way to do that and we’re going to set up society again slowly but surely. We’re going to do away with all those wretched creatures whom death has cheated. And, even though I pray otherwise, we may decide to kill you and those like you.

Those like me? he thought with a start. But he kept reading.

I’ll try to save you. I’ll tell them you’re too well armed for us to attack now. Use the time I’m giving you, Robert! Get away from your house, go into the mountains and save yourself. There are only a handful of us now. But sooner or later we’ll be too well organized, and nothing I say will stop the rest from destroying you. For God’s sake, Robert, go now, while you can!

I know you may not believe this. You may not believe that we can live in the sun for short periods now. You may not believe that my tan was only make-up. You may not believe that we can live with the germ now.

That’s why I’m leaving one of my pills.

I took them all the time I was here. I kept them in a belt around my waist. You’ll discover that they’re a combination of defebrinated blood and a drug. I don’t know myself just what it is. The blood feeds the germs, the drug prevents its multiplication. It was the discovery of this pill that saved us from dying, that is helping to set up society again slowly.

Believe me, it’s true. And escape!

Forgive me, too. I didn’t mean to hit you, it nearly killed me to do it. But I was so terribly frightened of what you’d do when you found out.

Forgive me for having to lie to you about so many things. But please believe this: When we were together in the darkness, close to each other, I wasn’t spying on you. I was loving you.

Ruth

He read the letter again. Then his hands fell forward and he sat there staring with empty eyes at the floor. He couldn’t believe it. He shook his head slowly and tried to understand, but adjustment eluded him.

He walked unsteadily to the bench. He picked up the small amber pill and held it in his palm, smelled it, tasted it. He felt as if all the security of mason were ebbing away from him. The framework of his life was collapsing and it frightened him.

Yet how did he refute the evidence? The pill, the tan coming off her leg, her walking in the sun, her reaction to garlic.

He sank down on the stool and looked at the mallet lying on the floor. Slowly, ploddingly, his mind went over the evidence.

When he’d first seen her she’d run from him. Had it been a ruse? No, she’d been genuinely frightened. She must have been startled by his cry, then, even though she’d been expecting it, and forgotten all about her job. Then later, when she’d calmed down, she’d talked him into thinking that her reaction to garlic was the reaction of a sick stomach. And she had lied and smiled and feigned hopeless acceptance and carefully got all the information she’d been sent after. And, when she’d wanted to leave, she couldn’t because of Cortman and the others. He had awakened then. They had embraced, they had–

His white-knuckled fist jolted down on the bench. “I was loving you.” Lie. Lie! His fingers crumpled up the letter and flung it away bitterly.

Rage made the pain in his head flare hotly and he pressed both hands against it and closed his eyes with a groan.

Then he looked up. Slowly he slid off the stool and placed the microscope back on its base.

The rest of her letter wasn’t a lie, he knew that. Without the pill, without any evidence of word or memory, he knew. He knew what even Ruth and her people didn’t seem to know.

He looked into the eyepiece for a long time. Yes, he knew. And the admission of what he saw changed his entire world. How stupid and ineffective he felt for never having foreseen it! Especially after reading the phrase a hundred, a thousand times. But then he’d never really appreciated it. Such a short phrase it was, but meaning so much.

Bacteria can mutate.

They came by night. Came in their dark cars with their spotlights and their guns and their axes and pikes. Came from the blackness with a great sound of motors, the long white arms of their spotlights snapping around the boulevard corner and clutching out at Cimarron Street.

Robert Neville was sitting at the peephole when they came. He had put down a book and was sitting there watching idly when the beams splashed white across the bloodless vampire faces and they whirled with a gasp, their dark animal eyes staring at the blinding lights.

Neville jumped back from the peephole, his heart thudding with the abrupt shock. For a moment he stood there trembling in the dark room, unable to decide what to do. His throat contracted and he heard the roar of the car motors even through the soundproofing on his house. He thought of the pistols in his bureau, the sub-machine gun on his workbench, thought of defending his house against them.

Then he pressed his fingers in until the nails dug at his palms. No, he’d made his decision, he’d worked it out carefully through the past months. He would not fight.

With a heavy, sinking sensation in the pit of his stomach he stepped back to the peephole and looked out.

The street was a scene of rushing, violent action illuminated by the bald glare of the spotlights. Men rushed at men, the sound of running boots covered the pavement. Then a shot rang out, echoing hollowly; more shots.

Two male vampires went thrashing down onto their sides. Four men grabbed them by the arms and jerked them up while two other men drove the glittering lance points of their pikes into the vampires’ chests.

Neville’s face twitched as screams filled the night. He felt his chest shuddering with labored breath as he watched from his house.

The dark-suited men knew exactly what they were doing. There were about seven vampires visible, six men and a woman. The men surrounded the seven, held their flailing arms, and drove razor-tipped pikes deep into their bodies. Blood spouted out on the dark pavement and the vampires perished one by one. Neville felt himself shivering more and more. Is this the new society? The words flashed across his mind. He tried to believe that the men were forced into what they were doing, but shock brought terrible doubt. Did they have to do it like this, with such a black and brutal slaughtering? Why did they slay with alarum by night, when by day the vampires could be dispatched in peace?

Robert Neville felt tight fists shaking at his sides. He didn’t like the looks of them, he didn’t like the methodical butchery. They were more like gangsters than men forced into a situation. There were looks of vicious triumph on their faces, white and stark in the spotlights. Their faces were cruel and emotionless.

Suddenly Neville felt himself shudder violently, remembering. Where was Ben Cortman?

His eyes fled over the street but he couldn’t see Cortman. He pressed against the peephole and looked up and down the street. He didn’t want them to get Cortman, he realized, didn’t want them to destroy Cortman like that. With a sense of inward shock he could not analyze in the rush of the moment, he realized that he felt more deeply toward the vampires than he did toward their executioners.

Now the seven vampires lay crumpled and still in their pools of stolen blood. The spotlights were moving around the street, flaying open the night. Neville turned his head away as the brilliant glare blazed across the front of his house. Then the spotlight had turned about and he looked again.
