Jane placed his palm flat against the solid wooden door, just above the deadbolt.  The lock emitted a short metallic scrape and a satisfying clunk as the bolt slid free of its mooring and nestled home within the door itself.  As if by magic, the brass doorknob turned on its own and the door swung away from the young man's steady hand.  Luckily the hinges were yet new and the previously imposing barrier made nary a sound as it revealed the room beyond to the three intruders waiting silently in the broad corridor.
"Well, that's useful," remarked Herman, with a vaguely dopey grin.
"Not as useful as you're thinking," Jane noted seriously.  He was, however, unable to keep from grinning in reply.  "It's not like I can crack bank vaults or anything."  The grin faded rapidly from Herman's too narrow face and the effect was, to Jane, disturbingly transformative.  He went from goofy clown to deadly hawk in less than five full seconds.  Jane's own smile slipped a little.
"Why not?"
The two stared at one another for a brief second before Jane began a stammered explanation.  "Well, I mean...I could, of course, but..."
"We don't have time for this," Audrey cut in, "Get artifact now, talk later."  The boys startled, guiltily, remembering their purpose.  "Move.  Now.  I hear the patrol coming."  A wicked grin all her own stole over Audrey's features, entirely different in nature than any of the smiles shared in the last minute.  She brought her hands together at chest level and cracked her knuckles loudly.  The scars on her hands and arms began to glow with a warm, golden light.  The boys fairly bolted into the room.
