Ershut looped the long end of the chain through the frame of the trailer hitch and brought it back to Zula’s ankle. Then he held out one hand and asked for the key to the padlock that was already there. Then demanded it. Then screamed for it. Finally someone slapped it into his hand. He undid the padlock on Zula’s ankle, swung the body away from the hasp, brought up the loose end of the chain, pushed a link over the hasp, then snapped it shut again.
