"Yeah, the chain goes through these iron cuff things and holds the whole row of slaves together, the other end goes out through a hole in the wall."
"Couldn't be better. I'm filing one of these links, and when it goes we're both free. See if you can't slip the chain through the holes in your shackles and lay it down without letting the next slave know what is happening. We'll wear these iron cuffs for now, there is no time to play around with them and they shouldn't bother us too much. Do the guards come through here at all during the night to check on the slaves?"
"Not since I've been here, just wake us up in the morning by pulling on the chain."
"Then let's hope that's what happens again tonight, because we are going to need plenty of time—there!" The file had cut through the link. "See if you can get enough of a grip on the other end of this link while I hold this end, we'll try and bend it open a bit." They strained silently until the opening gaped wide and the next link fitted through the cut.
They slipped the chain and laid it silently on the ground, then drifted noiselessly to the door.
"Is there a guard outside?" Jason asked.
"Not that I know. I don't think they have enough men here to guard all the slaves."
The door would not budge when they pushed against it, and there was just light enough to make out the large keyhole of a massive inset lock. Jason probed lightly with the pick and curled his lip in contempt.
"These idiots have left the key in the lock." He pulled off the stiffest of his leather wrappings and after flattening it out pushed it under the badly fitting bottom edge of the door, leaving just a bit to hold onto. Then he poked lightly at the key through the keyhole and heard it thud to the ground outside. When he pulled the leather back in the key was lying in the center of it. The door unlocked silently and a moment later they were outside, staring tensely into the darkness.
"Let's go! Run, get away from here," Snarbi said and Jason grabbed him by the throat and pulled him back.
