Edge. Part 24

A juddering memory pa.s.sed through Josh: Sophie, Sophie, and the message from that b.a.s.t.a.r.d consultant, what was his and the message from that b.a.s.t.a.r.d consultant, what was his name, Hammond, asking about organ donation and his baby name, Hammond, asking about organ donation and his baby girl still living while the machines kept her girl still living while the machines kept her "Josh."

small lungs pumping, blood moving through veins and arteries, feeding the brain that no longer "Josh, it's all right."

knew how to think, how to do anything but "It's OK, you're back."

He looked at Suzanne's eyes, the deep chestnut shade, and her hands were soft but strong, clasping his, giving rea.s.surance.

He was prostrate on the couch, Suzanne leaning over him, Yukiko holding his wrist to check his pulse. Then Suzanne raised his eyelid with her thumb.

"Has this been happening often?"

"Only when I think of... When I think about S-Sophie and the, the"

"Do you like blue ice-cream or purple?" asked Suzanne.

"Wha?"

Her fingertips came down, closing his eyes.

"Sleep."

His chin rocked to his chest.

This is weird.

When he awoke, it was after not being asleep, but in some other deep place where he could have moved or opened his eyes, if only he had wanted to. Suzanne's words were a warm ocean, surrounding and healing him. And then he came back into normal consciousness, feeling calm.

"Well." Yukiko looked at Suzanne. "Very nice, Dr d.u.c.h.esne. I learned hypnosis at med school, but not like that."

Petra said: "I told them about Sophie's condition."

He had never discussed it with her, but they had friends in common, and her expertise was investigation.

"How much better do you feel?" asked Suzanne.

"Well enough to eat just about anything."

"You haven't tasted my food yet," said Petra.

But the scents were compelling, and when they sat around the table, there was moussaka and salad, flat bread and houmous, along with stuffed vine leaves. Petra was clearly skilled. During the meal, they talked little; it was only when the coffee came out that they returned to their reason for gathering here.

"Josh did good work today." Petra tipped him a fingertip salute. "Cracked open a virapharm facility, using runaways as incubators. Which is Yukiko's area, except hers is the legal kind."

"You're in research?" Suzanne asked Yukiko. "Not a clinician?"

"Mostly research. Time-dependent transition-capable networks are my current interest."

"Uh-oh," said Petra.

"Look, they've got brains." Yukiko raised her eyebrows. "Josh has testosterone poisoning, maybe, but Suzanne's free from infection."

"I understood every single word you said about networks." Josh half-raised his coffee. "It was just the entire sentence that was meaningless."

"Terminal infection," said Suzanne. "But if you explain in simple words, he might understand. And maybe I will, too."

"It's just the old six-handshakes-from-the-pope kind of thing. Pick anyone on Earth, and you'll know someone who knows someone who knows that person."

"Sure."

"Look, if all your friends and acquaintances were randomly distributed across the globe like, you're as likely to know a rice-farmer in Vietnam as your next door neighbour then it would be quite natural that everybody seems to know everybody. But in reality, the people you know are the ones you work with, and the ones you live near."

"You're talking about nexus points."

"Right. There's a huge number of people with a smallish number of friends, and a small number of people who are hugely connected. Even Josh knows this, because it's how websites and physical servers const.i.tute the Web. It's a straight-line graph: the more connections you're talking about, the fewer sites or servers have that number. And for disease vectors, nanoviral or not, a small number of patients are ma.s.sively infectious carriers."

Suzanne said: "I've been telling Josh about complex systems, including human minds, and how they change fast, far faster than most people realise."

"Uh-huh." Yukiko nodded to Josh. "She's very fast. You understood what I meant about time-dependent networks, Suzanne?"

"I'm guessing that a person can be a natural nexus point like a webmovie star or Zak Tyndall, with thousands of people they can call on for a favour or have nexushood thrust upon them. If that's a word."

"Right person, right place, right time. A potential disease carrier can go through their lives free from infection, but if they happen to catch it, suddenly they're a nexus point."

Petra refilled everyone's cups.

"I'm just a simple copper. So Josh, who's going to win the Challenge? Bloods or Blades?"

"Probably."

"How many teams are in the Challenge?" asked Suzanne.

"Er, two."

Yukiko looked at Suzanne. "At least he can count above one."

[ SEVENTEEN ].

In the morning, Josh rolled off the couch as he came awake, landing in a crouched stance, checking the springiness in his legs.

"The warrior awakes." Petra was in the kitchen doorway. "Alert and ready for battle."

"And desperate to pee."

"Grab the bathroom while it's free. I'll make coffee."

"Deal."

To get to the bathroom, he had to pa.s.s the guest room with Suzanne inside. He paused, then entered the bathroom. Five minutes and a cold shower later, he was back out, wide awake.

In the kitchen, Yukiko, in T-shirt and baggy pyjama trousers, was staring at the coffee dripping into the pot. Her T-shirt's hologram showed a DNA double helix unwinding.

"Morning," said Josh. "How's the world's sharpest intellect?"

"Ugh."

"You want intelligent conversation from my sweetie," said Petra, "you need to wait for an hour. Longer, if we run out of coffee."

Yukiko's eyelids were almost shut. "Uh-huh.""So this would be a good time to challenge her to chess?"

"Only if you can wait till lunchtime for her to make a move."

Once the coffee was ready, Yukiko stumbled back to the bedroom, mug in both hands like an offering. Petra put a phone on the table, then sat down. Josh sipped his coffee, strong enough to make him blink.

"The covert core monitors," Petra said, "have registers of subscribers. Apart from Special Branch, there's a bunch of subscribing officers in Thames House and Vauxhall Cross." She meant MI5 and MI6. "One particular monitor scans for querybots targeting people of interest. If it notices a suspect querybot, it notifies the listener software on each subscriber's phone."

"And Richard Broomhall's a person of interest."

"Not him. His father."

"Whose biggest corporate enemy is Tyndall Enterprises. Which is why Yukiko showed us that stuff last night."

Not just because the fighters received virapharmbased treatment when injured.

"Right."

"And Zak Tyndall has friends in Whitehall."

"Uh-huh. So the reason for the monitor doesn't matter, not to you." Petra took a slug of coffee. "Mmm. Now, if you want to search beyond the London Transport net, you're going to have to fiddle with the subscriber list, similar to your ShieldIx hack."

"Er... Right."

"You can't stop the monitor detecting your querybot intrusion, but if you hack the monitor in advance, you can empty out its address book of who to notify. Like stuffing paper under an old-fashioned alarm bell, so it vibrates but there's no sound."

"And reinstate the address book afterwards," said Josh.

"Right. The monitor only checks new stuff: processes being sp.a.w.ned, runtime components coming into existence. Once your querybot is up and running, the monitor won't care. Then you can put the list back in place, so no one notices."

"So all I've got to do is find a way of hacking through to the monitor. That's not exactly trivial."

"Maybe it is." Petra slid the phone across the table. "For you, lover. Take a look in Favourite Apps. Everything you need is already loaded."

"I won't ask how you got this."

"And I won't tell you how I accidentally cloned a Special Branch phone while we had spook visitors."

"Good."

"Good."

They clinked their coffee mugs together.

"There's something else, though," said Petra. "Something that worries me, although I don't think we're under surveillance."

"Which is?"

"If there are watchers outside, there's a record of you spending the night with the three hottest babes in town."

"I'll be sure to look exhausted when I leave."

"Perhaps we should carry you out."

The world was grey, and Richard was grey. Even the sunshine was grey. He sat outside the park, upturned veil-cap on the ground, with four coins inside: all he had.

"Spare any... change?"But the busy feet had already walked past. In his listless state, he could not imagine walking that fast.

Am I going to die?

Perhaps at some point he could just let go of the world.

"There you go. Take it easy."

Coins spilling from a curled palm, a crouched woman straightening and walking on.

"Er, thank... you."

He woke up enough to check for streetcams. This seemed to be a blind spot, so he relaxed back against the brickwork. Other people walked past workers heading for the station and a few more coins tinkled into his cap.
