"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. "Funny killing. Dead, but not eaten. No blood. As if they just fell over. It has our medical technicians half crazy. Nothing wrong. No reason that they should have died."
"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 beinning of a snarl. Ichabod crouched, toes dug into the floor – listening, waiting.
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 beginning of the end. It is the winding path that grows to the roaring road of war.
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.
And some he knew and some were mystery, and others he would guess at. But there was one that held a hint of horror.
He pressed himself close against the ground and held his ugly head out straight and flat and closed his perceptions against the throbbing of the night, concentrating on the thing that was coming up the hill.
There were two of them and the two were different. A snarl rose in his mind and bubbled in his throat and his tenuous body tensed into something that was half slavering expectancy and half cringing outland terror.
He rose from the ground, still crouched, and flowed down the hill, angling to cut the path of the two who were coming up.
Jenkins was young again, young and strong and swift – swift of brain and body. Swift to stride along the wind-swept, moon-drenched hills. Swift to hear the talking of the leaves and the sleepy chirp of birds – and more than that.
Yes, much more than that, he admitted to himself. The body was a lulu. A sledge hammer couldn't dent it and it would never rust. But that wasn't all.
Never figured a body's make this much difference to me. Never knew how ramshackle and worn out the old one really was. A poor job from the first, although it was the best that could be done in the days when it was made. Machinery sure is wonderful, the tricks they can make it do.
It was the robots, of course. The wild robots. The Dogs had fixed it up with them to make the body. Not very often the Dogs had much truck with the robots. Got along all right and all of that – but they got along because they let one another be, because they didn't interfere, because neither one was nosey.
There was a rabbit stirring in his den – and Jenkins knew it. A raccoon was out on a midnight prowl and Jenkins knew that, too – knew the cunning, sleek curiosity that went on within the brain behind the little eyes that stared at him from the dump of hazel brush. And off to the left, curled up beneath a tree, a bear was sleeping and dreaming as he slept – a glutton's dream of wild honey and fish scooped out of a creek, with ants licked from the underside of an upturned rock as relish for the feast.
