Wai, he datavised. We need a lift. Quickly, please.
On my way, Marcus.
Strange way for xenocs to communicate, Schutz datavised. What did they do that for? If they wanted to make sure we stayed, they could have disabled the airlock.
The MSV swooped over the edge of the shell, jets of twinkling flame shooting from its thrusters.
Beats me, Marcus datavised. But we'll find out.

Marcus called his council of war five hours later, once everyone had a chance to wash, eat, and rest. Opinion was a straight split: the crew wanted to continue investigating the xenoc ship, Antonio and his colleagues wanted to leave. For once Jorge had joined them, which Marcus considered significant. He was beginning to think young Karl might have been closer to the truth than was strictly comfortable.
The dish is just rock with a coating of aluminium sprayed on, Katherine said. There's very little aluminium left now, most of it has boiled away. The tower is a pretty ordinary silicon/boron composite wrapped round a titanium load structure. The samples Wai cut off were very brittle.
Did you carbon-date them? Victoria asked.
Yeah. She gave her audience a laboured glance. Give or take a decade, it's thirteen thousand years old.
Breath whistled out of Marcus's mouth. Jesus.
Then they must have been rescued, or died, Roman said. There's nobody left over there. Not after that time.
They're there, Antonio growled. They stole our exoskeletons.
I don't understand what happened to the exoskeletons. Not yet. But any entity who can build a ship like that isn't going to go creeping round stealing bits of space armour. There has to be a rational explanation.
Yes! They wanted to keep us over there.
What for? What possible reason would they have for that?
It's a warship, it's been in battle. The survivors don't know who we are, if we're their old enemies. If they kept us there, they could study us and find out.
After thirteen thousand years, I imagine the war will be over. And where did you get this battleship idea from anyway?
It's a logical assumption, Jorge said quietly.
Roman turned to Marcus. My guess is that some kind of mechanoid picked them up. If you look in one of the lockers you'll probably find them neatly stored away.
Some automated systems are definitely still working, Schutz said. We saw the blisters. There could be others.
That seems the most remarkable part of it, Marcus said. Especially now we know the age of the thing. The inside of that ship was brand new. There wasn't any dust, any scuff marks. The lighting worked perfectly, so did the gravity, the humidity hasn't corroded anything. It's extraordinary. As if the whole structure has been in zero-tau. And yet only the shell is protected by the molecular-bonding-force generators. They're not used inside, not in the decks we examined.
However they preserve it, they'll need a lot of power for the job, and that's on top of gravity generation and environmental maintenance. Where's that been coming from uninterrupted for thirteen thousand years?
Direct mass-to-energy conversion, Katherine speculated. Or they could be tapping straight into the sun's fusion. Whatever, bang goes the Edenist He3 monopoly.
We have to go back, Marcus said.
NO! Antonio yelled. We must find the gold first. When that has been achieved, you can come back by yourselves. I won't allow anything to interfere with our priorities.
Look, I'm sorry you had a fright while you were over there. But a power supply that works for thirteen thousand years is a lot more valuable than a whole load of gold which we have to sell furtively, Katherine said levelly.
I hired this ship. You do as I say. We go after the gold.
We're partners, actually. I'm not being paid for this flight unless we strike lucky. And now we have. We've got the xenoc ship, we haven't got any gold. What does it matter to you how we get rich, as long as we do? I thought money was the whole point of this flight.
Antonio snarled at her, and flung himself at the floor hatch, kicking off hard with his legs. His elbow caught the rim a nasty crack as he flashed through it.
Victoria? Marcus asked as the silence became strained. Have the satellite arrays found any heavy metal particles yet?
There are definitely traces of gold and platinum, but nothing to justify a rendezvous.
In that case, I say we start to research the xenoc wreck properly. He looked straight at Jorge. How about you?
I think it would be prudent. You're sure we can continue to monitor the array satellites from here?
Yes.
Good. Count me in.
Thanks. Victoria?
She seemed troubled by Jorge's response, even a little bewildered, but she said: Sure.
Karl, you're the nearest thing we've got to a computer expert. I want you over there trying to make contact with whatever control network is still operating.
You got it.
From now on we go over in teams of four. I want sensors put up to watch the airlocks when we're not around, and I want some way of communicating with people inside. Start thinking. Wai, you and I are going to secure Lady Mac to the side of the shell. OK, let's get active, people.
•••
Unsurprisingly, none of the standard astronautics industry vacuum epoxies worked on the shell. Marcus and Wai wound up using tether cables wrapped round the whole of the xenoc ship to hold Lady Mac in place.
Three hours after Karl went over, he asked Marcus to join him.
Lady Mac 's main airlock tube had telescoped out of the hull to rest against the shell. There was no way it could ever be mated to the xenoc airlock rectangle, but it did allow the crew to transfer over directly without having to use exoskeleton armour and the MSV. They'd also run an optical fibre through the xenoc airlock to the interior of the ship. The hatch material closed around it forming a perfect seal, rather than slicing it in half.
Marcus found Karl just inside the airlock, sitting on the decking with several processor blocks in his lap. Eight blisters were slowly circling round him; two on the wall were stationary.
Roman was almost right, he datavised as soon as Marcus stepped out of the airlock. Your exoskeletons were cleared away. But not by any butler mechanoid. Watch. He lobbed an empty recording flek case onto the floor behind the blisters. One of them slid over to it. The green composite became soft, then liquid. The little plastic case sank through it into the blister.
I call them cybermice, Karl datavised. They just scurry around keeping the place clean. You won't see the exoskeletons again, they ate them, along with anything else they don't recognize as part of the ship's structure. I imagine they haven't tried digesting us yet because we're large and active; maybe they think we're friends of the xenocs. But I wouldn't want to try sleeping over here.
Does this mean we won't be able to put sensors up?
Not for a while. I've managed to stop them digesting the communication block which the optical fibre is connected to.
How?
He pointed to the two on the wall. I shut them down.
Jesus, have you accessed a control network?
No. Schutz and I used a micro SQUID on one of the cybermice to get a more detailed scan of its electronics. Once we'd tapped the databus traffic it was just a question of running standard decryption programs. I can't tell you how these things work, but I have found some basic command routines. There's a deactivation code which you can datavise to them. I've also got a reactivation code, and some directional codes. The good news is that the xenoc program language is standardized. He stood and held a communication block up to the ceiling. This is the deactivation code. A small circle of the ceiling around the block turned dark. It's only localized, I haven't worked out how to control entire sections yet. We need to trace the circuitry to find an access port.
