BZRK (BZRK 1)

Sticky liquid squeezed up between the lids and then, when the top lid began to pull away, stretched like chewed gum until it snapped.

Tears.

Vincent had been through a crying jag on another mission and had ended up with his biot all the way down the face and trapped in running snot.

But these weren’t weeping tears, just lubrication.

The upper lid receded, zooming across the icy white and then over the iris. Vincent would have found it exhilarating if he were the sort of person who did exhilaration.

There were many parts of the human body that were disturbing up close. But few more surprisingly so than a human iris. What looked like blue ice from a distance was an eye-of-Jupiter storm up close. Right at the outer edges Vincent saw blue, or at least a gray that was like blue. But it was not smooth; rather it was a twisted, fibrous mess, thousands of strands of raw muscle, all aimed inward toward the pupil, all with the job of expanding or contracting the iris to let in more or less light.

Clos

e up—and it was impossible to get any more close up than V2, perched on the very edge of the lid—the iris looked a bit like layer upon layer of gray-and-orange worms, thinner at the outer edge of the iris, stronger at the rim of the pupil.

The pupil itself swept by below, a terrible, deep, black-in-black hole, a pit. But then if you looked straight down and caught just the right light, you could actually see to the bottom of that pit, down to the random blood vessels and the juncture that was the attachment point for the optic nerve.

Vincent did not get that image this time. Not in candlelight and soft, yellow fluorescence. He just saw the pupil as a black, circular lake, growing wider as the snake muscles of the iris shortened themselves fractionally.

The biot was 400 microns—less than half a millimeter—long and equally tall. But the m-sub feel of it—the image a biot runner experienced—how it felt to him, made it seem to be about seven feet long and almost that tall. To the twitcher it felt like something the size of a large SUV.

In mack it was the size of a healthy dust mite. But when you’re a dust mite, you don’t feel tiny. You feel big.

As the eyelid reached its apogee, V2 jumped off. The biot landed on the milky sea, then flattened itself down as the eyelid zoomed away, hesitated, then came sweeping back overhead like a gooey pink blanket.

Vincent thought, Light, and Lo! There was light. Twin phosphorescing organs on the biot’s head spread ultraviolet light.

He waited for the eyelid to come back up again, ate another bite of poppadom, jabbed a single leg into the underside of the eyelid and let it pull it up and over the slick eyeball, and sipped his water.

It was quite a ride. And as Vincent watched the waiter refill his glass he felt a frisson, a sort of echo of what V2 felt, its back sliding along the slickery surface of the eyeball.

The trick with entering the brain by way of the eye was to reach the hole at the back of the bony eye socket. It was possible for a biot to cut through bone, but it was never quick or safe. It was the kind of thing that would start a firestorm of bodily defenses.

Reaching the hole—Vincent had forgotten the official name for it—was best done by circumnavigating the eyeball. In the m-sub it was a long walk. And all of it through the dragging wetness of tears and the vertiginous movements of the orb looking this way or that.

The two other paths to the brain—through the ear or the nose—had bigger difficulties. Earwax and the distinct possibility of a watery blockage in the one, and unimaginable filth in the other: pollen, mucus, all manner of microfauna and microflora.

This was better. For one thing you could, if you chose, sink a probe into the optic nerve and get some macro optics—see a bit of what the target was seeing, though it was usually very rough gray scale.

The second greatest threat to a biot was getting lost. When you were the size of a mite, the human body was the equivalent of roughly five miles from end to end. So V2 dutifully made its way around the eyeball, squeezed between membranes, became a bit disoriented, before finally reaching the optic nerve just as Vincent’s dinner was being placed before him.

And then, quite suddenly, he came across not the second greatest, but the single greatest threat to a biot.

They attacked with blazing speed, wheels spinning but still getting traction on the eyeball. He saw three of them immediately as they raced around from behind the redwood tree of the optic nerve.

Which answered the question of whether Professor Liselotte Osborne—leading expert on nanotechnology, consultant to MI5, the woman who could either push or derail the security agency’s investigation into nanotechnology—was free or infested.

Two more nanobots were behind V2.

Five to one odds. Although if he hung around for long, more would be on the way.

Who was the twitcher? Vincent watched the way the nanobots moved in. Too reckless. And platooned into two packs, mixing relatively benign spinners and fighters. Not an experienced hand. Not Bug Man. Not Burnofsky. Not even the new one, what was it she called herself? One-Up. Yeah. Not her, either. All of them could run five nanobots as individuals, rather than two platoons.

Vincent tasted the curry. Very hot.

He chewed carefully. It was important to chew thoroughly. It helped digestion, and digestion was often a problem during these long trips across multiple time zones.

And at the same time Vincent spun V2 toward the two nanobots he wasn’t supposed to have noticed.
