City

Ichabod squatted on his haunches on the floor and looked up at Jenkins.

"There sure ain't none," he said. "We checked her, forty ways from Sunday, and all the factors, check. They all add up. There isn't any past."

"There isn't any room," said Joshua. "You travel back along the line of time and you don't find the past, but another world, another bracket of consciousness. The earth would be the same, you see, or almost the same. Same trees, same rivers, same hills, but it wouldn't be the world we know. Because it has lived a different life, it has developed differently. The second back of us is not the second back of us at all, but another second, a totally separate sector of time. We live in the same second all the time. We move along within the bracket of that second, that tiny bit of time that has been allotted to our particular world."

"The way we keep time was to blame," said Ichabod. "It was the thing that kept us from thinking of it in the way it really was. For we thought all the time that we were passing through time when we really weren't, when we never have. We've just been moving along with time. We said, there's another second gone, there's another minute and another hour and another day, when, as a matter of fact the second or the minute or the hour was never gone. It was the same one all the time. It had just moved along and we had moved with it."

Jenkins nodded. "I see. Like driftwood on the river. Chips moving with the river. And the scene changes along the river bank, but the water is the same."

"That's roughly it," said Joshua. "Except that time is a rigid stream and the different worlds are more firmly fixed in place than the driftwood on the river."

"And the cobblies live in those other worlds?"

Joshua nodded. "I'm sure they must."

"And now," said Jenkins, "I suppose you are figuring out a way to travel to those other worlds."

Joshua scratched softly at a flea.

"Sure he is," said Ichabod. "We need the space."

"But the cobblies-"

"The cobblies might not be on all the worlds," said Joshua. "There might be some empty worlds. If we can find them, we need those empty worlds. If we don't find space, we are up against it. Population pressure will bring on a wave of killing. And a wave of killing will set us back to where we started out."

"There's already killing," Jenkins told him quietly.

Joshua wrinkled, his brow and laid back his ears. "Fu

"But they did," said Ichabod.

Joshua hunched himself closer, lowered his voice. I'm afraid, Jenkins. I'm afraid that-"

"There's nothing to be afraid of."

"But there is. Angus told me. Angus is afraid that one of the cobblies... that one of the cobblies got through."

A gust of wind sucked at the fireplace throat and gamboled in the eaves. Another gust hooted in some near, dark corner. And fear came out and marched across the roof, marched with thumping, deadened footsteps up and down the shingles.

Jenkins shivered and held himself tight and rigid against another shiver. His voice grated when he spoke.

"No one has seen a cobbly."

"You might not see a cobbly."

"No," said Jenkins. "No. You might not see one."

And that is what Man had said before. You did not see a ghost and you did not see a haunt – but you sensed that one was there. For the water tap kept dripping when you had shut it tight and there were fingers scratching at the pane and the dogs would howl at something in the night and there'd be no tracks in the snow.

And there were fingers scratching on the pane.

Joshua came to his feet and stiffened, a statue of a dog, one paw lifted, lips curled back in the bei

The scratching came again.

"Open the door," Jenkins said to Ichabod. "There is something out there wanting to get in."

Ichabod moved through the hushed silence of the room. The door creaked beneath his hand. As he opened it, the squirrel came bounding in, a grey streak that leaped for Jenkins and landed in his lap.

"Why, Fatso," Jenkins said.

Joshua sat down again and his lips uncurled, slid down to hide his fangs, Ichabod wore a silly metal grin.

"I saw him do it," screamed Fatso. "I saw him kill the robin. He did it with a throwing stick. And the feathers flew. And there was blood upon the leaf."

"Quiet," said Jenkins gently. "Take your time and tell me. You are too excited. You saw someone kill a robin."

Fatso sucked in a breath and his teeth were chattering.

"It was Peter," be said. "Peter?"

"Peter, the webster."

"You said he threw a stick?"

"He threw it with another stick. He had the two ends tied together with a cord and he pulled on the cord and the stick bent-"

"I know," said Jenkins. "I know."

"You know! You know all about it?"

"Yes," said Jenkins, "I know all about it. It was a bow and arrow."

And there was something in the way he said it that held the other three to silence, making the room seem big and empty and the tapping of the branch against the pane a sound from far away, a hollow, ticking voice that kept on complaining without the hope of aid.

"A bow and arrow?" Joshua finally asked. "What is a bow and arrow?"

And what was it, thought Jenkins.

What is a bow and arrow?

It is the begi

It is a plaything and a weapon and a triumph in human engineering.

It is the first faint stirring of an atom bomb.

It is a symbol of a way of life.

And it's a line in a nursery rhyme. Who killed Cock Robin.

I, said the sparrow. With my bow and arrow, I killed Cock Robin.

And it was a thing forgotten. And a thing relearned. It is the thing that I've been afraid of.

He straightened in his chair, came slowly to his feet. "Ichabod," he said, "I will need your help." "Sure," said Ichabod. "Anything you like." "The body," said Jenkins. "I want to wear my new body. You'll have to unseat my brain case-"

Ichabod nodded. "I know how to do it, Jenkins." Joshua's voice had a sudden edge of fear. "What is it, Jenkins? What are you going to do?"

"I'm going to the Mutants," Jenkins said, speaking very slowly. "After all these years, I'm going to ask their help."

The shadow slithered down the hill, skirting the places where the moonlight flooded through forest openings. He glimmered in the moonlight – and he must not be seen. He must not spoil the hunting of the others that came after.

There would be others. Not in a flood, of course, but carefully controlled. A few at a time and well spread out so that the life of this wondrous world would not take alarm.

Once it did take alarm, the end would be in sight. The shadow crouched in the darkness, low against the ground, and tested the night with twitching, high-strung nerves. He separated out the impulses that he knew, cataloguing them in his knife-sharp brain, filing them neatly away as a check against his knowledge.
