It takes a lot of climbing before he finds one, set in the opposite side of the column from the one far below them. On leaning over, he discovers that he doesn't have the reach to press both of its buttons, at least not and stay on the ladder.
"Bugger," he mutters. "Asterion? You have nice long arms. I found us a panel but I can't get it open. If I move up out of your way, can you get at the release catches? And, uh, try not to drop the panel. It'd be a good idea for us to put it back when we're done exploring, and I don't fancy trying to haul it up the ladder from the bottom of this hole."
"Sure," says Asterion. He waits until he hears Miles stop climbing again, then moves up and reaches over. The panel comes off easily, and he turns it carefully to push it through the opening and lay it on the floor of the dark but comparatively well-lit room.
Asterion pokes his head out, looks around, then retracts it and whispers back. "Big room, lots of little lights from displays and stuff. No people, no windows. One door."
"All right, time to go exploring," murmurs Miles. "Can you get back down to the basement, put the panel back on, and come back up here? It seems to me that if we get out this way, it would be advantageous to make that as un-obvious as possible."
There are not. There's a refrigerator at the back of the long room, and a row of three enormous walk-in freezers with polished metal doors. Miles gets on tiptoe to peer through the square glass viewport in the front of one. Blackness. He contemplates turning on a light.
"Find anything?" he asks in a whisper.
"I don't believe we can get out this way," Miles whispers back. "Damn. But there might be food in the refrigerator, if I know lab techs..." That was a twenty-four-hour ration bar, but this is an eight-foot-tall teenage boy with God knows what kind of accelerated metabolism. Miles peers into the fridge and extracts an illicitly stored sandwich accompanied in its rough paper package by a large pear. "Hungry?" He offers them to his companion with a conjuror's flourish.
"Not as hungry as usual," he says, but he still accepts and devours the stolen meal. "What were you looking at when I got here?"
Then he looks inside.
Clear plastic drawers containing clear plastic trays, stacked in tall cabinets, rows and rows and rows and endless rows of them. Everything neatly labelled. And the individual articles arranged on these trays are... some kind of frozen samples.
Tissue samples, perhaps?
"My god," he breathes, stunned. "This must be it. Ryoval's treasure chamber - the black heart of his black art - look in there, Asterion." He moves aside. "See all those little frozen sticks? Tissue samples. What Baron Ryoval uses to cook up his bio-slaves. Every little tidbit of flesh he's begged, bought, borrowed, or stolen in the last century, neatly labelled and waiting to be used on his next project. Its value is incalculable."
"We can't pick it up and carry it off," says the practical Asterion. "What's its value to us?"
"Me neither," says Miles. "Did you know these freezers have a temperature control that goes up to two hundred degrees centigrade, to heat-sterilize the interior for cleaning and maintenance?"
In short order, he has the monitor feed from the freezers spliced so that one freezer delivers its output to an optical data recorder while its neighbour covers for its absence via a splitter cable. He sits very still for a minute or two, letting the recorder do its work. Then he fusses with the arrangement again until the data recorder is broadcasting its loop of quiescent freezer inactivity on all three of the monitor channels, and the live feeds from the freezers hang loose.
"And now that the monitors are well and truly buggered... come here," he says, beckoning Asterion to the first freezer. "Time for your very first tactics lesson. There's the temperature dial. Turn it up, gentle as can be, until it hits maximum. Then do the other two."
He retrieves the cutters, pops the panel off the column, and descends with the hand light clipped to his shirt collar.
Asterion casts a thoughtful glance around the room before following Miles down, replacing the panel yet again on the way.
"Back into the duct first, I think," he declares. "It's easier to see out that grille than it would be if we started trying panels again. Less risk of popping out of a hole only to find we've surprised a guard squadron on break."
"All right," says Asterion. He follows Miles to the duct and boosts him up into it.
His boots are lost to him, but he does find a musty old bin of spare House Ryoval guard uniforms. All much too big for him and much too small for Asterion, but Miles filches several pairs of warm black socks, donning two layers and stuffing the rest in his pockets; on reflection, he also puts on the smallest available combination of red tunic and black trousers and red-lined black jacket, rolling up everything that needs rolling up so the trousers don't drag on the floor and the sleeves don't fall over his hands. A few more minutes of searching turn up a second bin containing boots, from which he again takes the smallest. Adding a third layer of socks gets them to stay on his feet with adequate stability. Then he bundles up the biggest available size of everything, on the theory that some of it might fit his new recruit-trainee at least well enough to be worth trying, and packs all the bins away as close as possible to the condition in which he found them.
Thusly equipped, he creeps out into the hallway and explores a little more. There at the end of the hall, a hatch that strongly resembles the one Miles was thrown down not too many hours ago; he notes its position but doesn't try to open it just yet. First he wants to see what other useful articles he might plunder from this basement.
A second storage room contains mainly spare glassware. Miles is not yet desperate enough to filch a couple of test tubes for use as improvised weapons, but he does pick up a handful of styluses and a small stack of sticky-notes from a bin of office supplies. In a pinch, they'll make better lockpicking devices than his bare hands. Likewise the two pairs of gloves, light and heavy - if he could find any that might accomodate Asterion's enormous hands and talonlike fingernails, he'd grab them, but they don't seem to stock the appropriate size. Speaking of lab gear, though, is that a drawer full of lab coats? Why yes! Miles grabs biggest and smallest in those too. Beggars can be choosers, if they're willing to steal...
The next few storage rooms he tries contain more office supplies, legions of spare data cables, and a bin of defunct small electronics. Miles pockets a few rolls of cable and a couple of dead widgets - a wristcom and a chrono - plus a small tool-case he finds next to the widget bin. It should make a much better lockpick than a bunch of styluses. Pity there aren't any working hand lights around with which to augment his extremely limited supply.
Now thoroughly laden, he goes back to the subbasement hatch and opens it up. It's one of the ones with no handle. For convenience's sake, he jams it open with a spare stylus before he descends.
"Asterion?" he calls, as loudly as he dares, which isn't very. "You still down here?"
