(Pause.) 'As long as he doesn't turn on us, your grace. Mark my words. As long as he doesn't turn on us…'
The tape clicked to an end. Mike stared at the poisonous thing, unwilling to rewind it and listen again. It wasn't as if he hadn't had his suspicions, but…
Slowly a new and even more unwelcome supposition inserted itself into his mind.
The thoughts were coming too fast. Mike stood up tiredly, stretched the kinks out of his shoulders, glanced at the clock. It was four in the afternoon: a little early to go home, normally, but…

Miriam cleared her throat.
Heads nodded. Many of them had been at that particular meeting.
'You probably think I asked you here today because a lot has happened in the past year. In particular,
She leaned over the laptop-sitting on a lectern borrowed from the shrine to the household deities-and tapped the space bar. PowerPoint was running, but the projector-'Someone check that-'
Huw poked at the projector. 'It's on,' he confirmed. A moment later the screen beside her (a bleached, lime- washed canvas stretched flat within a monstrously baroque gilt picture frame) flickered to life.
'Okay.' Miriam focused on her notes. She'd spent almost twelve hours working on this presentation, far less than the subject deserved but as much as she'd been able to steal between her other duties over the past week. 'Here's what we know for sure: Almost ten months ago, Sir Matthias, who had been participating in at least one little conspiracy against his grace the duke, vanished. We've subsequently learned that he handed himself in to the DEA in return for immunity'-shocked muttering from the back of the room told her that not everybody present had known even that much-'and the DEA handed him on to some kind of black intelligence team called the Family Trade Organization. They're the folks behind the series of raids that shut down the east coast network. A number of us have been compromised, including myself and her grace my mother. FTO subsequently captured at least two of our number and coerced them to act as mules, and at least one of their agents was in the grounds of the Summer Palace earlier this year when the pretender made his bid for the succession.'
She paused. The muttering hadn't died down. 'Can you save it for later?' she called.
'Silence!' This a deep bellow from Sir Alasdair, at the back corner of the room. 'Pray continue, milady.'
'Thank you… As I was about to say, anything we decide to do now has to take account of the facts that the US government is aware of us; considers us to be a threat; has developed at the very least a minimal capability to send operatives over here; and we can presume that the explosion at the Hjalmar Palace was also their work. And the news doesn't get any better from there. Um.'
She ran the next slide. A photograph of a shattered white dome on a forested hillside. Fast forward again: structures inside the dome, indistinct in the gloom but clearly showing how enormous it was. Next slide: a sealed metal door set in a concrete wall. 'On the other side of this door, Sir Huw discovered hard vacuum.' Next slide: a view down into the valley, thick mist swirling around the crack in the dome's side. 'A door into an apparently endless vacuum. The cloud you're looking at is condensation where the air pressure around the dome drops. It's too dangerous to approach closer, or we'd have gone back to try and seal it-our people were lucky to get away alive-but it's not any kind of vacuum pump
rather than the transient connection we make when we world-walk. But we have no idea how it works or why there's no, uh, world there. Maybe there used to be and the gate needs to be anchored in some way? We don't know.'
The chatter had subsided into a stunned silence. Miriam glanced round the shocked faces in front of her. 'Sir Huw has also conducted some topological analysis on the family knotworks,' she said forcefully. 'He generated a series of variants and checked them-not to world-walk, but to see if he could feel them. He generated them using Mathematica. It turns out that the family knots can be derived by following a fairly simple formula, and there are three constants that, if you vary them, give rise to different knots that give him the family headache.' Next slide: a polynomial equation. 'Apparently, this is the key to our ability-it's the Alexander polynomial describing the class of knots to which ours belong. No, I don't understand it either, but it turns out that by tweaking some of these coefficients we get different knots that include the two we already know of.
'Any given knot, starting in any given world, seems to act as a binary switch: Focus on it and you can walk from your starting world into a single destination determined by the knot you use.'
Someone had thoughtfully placed a wine goblet by her laptop. Miriam paused to take a sip.
'There's more. The conventional wisdom about how much we can carry, about the impossibility of moving goods using a carriage or a wheelbarrow? It's somewhat… wrong. It's true that you can't
