Dean Koontz - By the Light of the Moon

'Hey, yeah. I was in maybe tenth grade. Our science teacher showed us a picture of it.'

'They photographed it with a camera hooked up to a powerful electron microscope.'

'But that was pretty much just a tiny sign, not a machine,' she objected. 'It didn't do anything.'

'Yeah, but platoons of researchers have been burning up a lot of development funds designing nanomachines that will work. Machines that already do.'

'Teeny-tiny fairy machines.'

'If you want to think of it that way, yes.'

'Why?'

'Eventually, when the technology's perfected, the applications are going to be incredible, virtually infinite, especially in the medical field.'

Jilly tried to imagine at least one of the infinite applications of teeny-tiny machines performing teeny-tiny tasks. She sighed. 'I've spent too much of my life writing jokes, telling jokes, and stealing jokes. Now I feel like a joke. What applications?'

He pointed to the laptop screen. 'I've sourced up an interview that Proctor did a few years ago. It's in layman's terms, easy to grasp. Even I understood it.'

'Why don't you condense it for me?'

'All right. First, an application or two. Imagine a machine tinier than a blood cell, composed of a handful of atoms, but with the capacity to identify plaque on blood-vessel walls and the ability to remove it mechanically, safely. They're biologically interactive in function but fashioned from biologically inert atoms, so your body's immune system won't be triggered by their presence. And now imagine receiving an injection containing hundreds of thousands of these nanomachines, maybe millions.'

'Millions?'

He shrugged. 'Millions would fit in a few cc of a carrier fluid like glucose. It'd be a smaller syringe than Proctor used with us.'

'Creepy.'

'I suppose when the first vaccines were developed, people back then thought it was creepy to be injected with dead germs in order to build up an immunity against live ones.'

'Hey, I still don't like the sound of it.'

'So anyway, these millions of nanomachines would circulate endlessly through your body, searching out plaque, gently scrubbing it away, keeping your circulatory system as clean as a whistle.'

Jilly was impressed. 'If that ever hits the market, welcome to the age of the guilt-free cheeseburger. And you know what? This is starting to sound a little familiar.'

'I'm not surprised.'

'But why should it?'

Instead of answering her question, he said, 'Nanomachines could detect and eliminate colonies of cancer cells before the tumor was half as large as the head of a pin.'

'Hard to see the downside to all this,' Jilly said. 'But we know for sure there is one. And why're you being enigmatic? Why do you think this should sound familiar to me?'

In the corner, Shep said, 'Herethere.'

'Oh, shit!' Dylan bolted from his chair so fast that he knocked it over.

'Herethere.'

Closer to Shepherd than Dylan was, Jilly reached the kid first. Approaching him, she didn't see anything out of the ordinary, no red tunnel to California or to anywhere else.

Shepherd no longer leaned with the top of his skull jammed into the juncture of walls. He had taken a step backward. He stood erect, head up, eyes focused intently on something that appeared to be a lot more interesting than anything Jilly could see.

He had raised his right hand again, as if taking an oath, but he hadn't started to wave. As Jilly arrived at his side, Shep reached in front of his face, to the point in midair at which he'd been staring, and between his thumb and forefinger, he took a pinch of… a pinch of nothing, as far as she could tell. When he tweaked that pinch of air, however, the corner of the room began to fold in upon itself.

'No,' Jilly said breathlessly, and though she knew that Shepherd often recoiled from contact, she reached in front of him and put her hand atop his. 'Don't do this, sweetie.'

Multiple segments of the tricolored stripes on the wallpaper, previously mismatched only at the corner, now bent every which way at radical angles to one another, and the corner became so distorted that Jilly could not follow the floor-to-ceiling line of it.

At Shep's other side, Dylan placed one hand on his brother's shoulder. 'Stay here, buddy. Right here with us, safe with us.'

The folding motion halted, but the corner remained tweaked into a surreal geometry.

Jilly seemed to be looking at this small portion of the world through an octagonal prism. Her mind rebelled at the spectacle, which defied reason to an extent that even the radiant tunnel in the wall had not done.

With the palm of her right hand still against the back of Shep's right hand, Jilly was afraid to struggle with him, for fear that any movement she made would further fold here to there, wherever there might be this time. 'Smooth it out, honey,' she urged, tremors creasing her voice as strangely as the walls were folded before her. 'Let it go, sweetie. Smooth it out like it ought to be.'

Between thumb and forefinger, Shepherd still pinched the fabric of reality.

Slowly he turned his head to look at Jilly. He met her eyes as directly as he had met them only once before: when he'd been in the backseat of the Expedition outside the house on Eucalyptus Avenue, just after Dylan had rushed away without explanation. Then, Shep had flinched from eye contact, had looked at once away.

This time he held her gaze. His green eyes appeared as deep as oceans and seemed to be lit from within.

'Do you feel it?' he asked.

'Feel what?'

'Feel how it works, the round and round of all that is.'

She supposed that by transmission through his hand, he expected her to feel what he felt between his thumb and forefinger, but she was aware only of his warm skin, of the sharpness of his metacarpals and his knuckles. She expected to detect tremendous tension, as well, to have an awareness of how hard Shep must be straining to achieve this incredible feat, but he seemed to be relaxed, as though folding this place to another required no more effort than folding a towel.

'Do you feel the beautiful of all that is?' he asked, addressing her with a directness that had no element of autistic detachment.

As beautiful as the secret structure of reality might be, this close an encounter with the mystery of it did not delight her as it seemed to enchant Shepherd, but instead crystallized an ice of terror in her bones. She wanted not to understand, but only to persuade him to close this gateway before he fully opened it.

'Please smooth it out, sweetie. Smooth it out again so I can feel how it unfolds.'

Although her father had been shot to death a year ago in a drug deal gone bad, Jilly had the fearful notion that if Shepherd didn't unfold this, if instead he folded it all the way and took them from here to there , she would abruptly come face to face with her hateful old man, as she had often opened the apartment door to the sight of his dangerous smile. She expected Shep to swing wide the gate to Hell as easily as he opened a gate to California, facilitating a father-and-daughter reunion. Come to collect the eye insurance, baby girl. You got the eye-insurance premium? As though Shep might unwittingly give her father a chance to reach out from Beyond to make good on his unfulfilled threat, blinding her in not one eye, but in both.

Shep's gaze drifted away from her. He refocused on his thumb and forefinger.

He had tweaked the pinch of nothing from left to right. Now he tweaked it right to left.

The wildly angled stripes in the wallpaper realigned themselves. The unbroken line of the corner, floor to ceiling, became clearly visible again, without a single zig or zag. What she had seemed to see through an octagonal prism, she here saw undistorted.
