The next room was larger. Only one end was lit. In the gloom was a dimly lit outline. As eyes adjusted the nature of the object dawned on the small audience, 

"Ladies and Gentlemen, meet Jean. "

A beautiful young woman became visible as the lighting rose a little. She was tall and slender and quite naked. Her neck and wrists were trapped in a rusty iron yoke, which itself was suspended from the ceiling by heavy chains. Her gaze was forced upwards. A pole hung from the ceiling had had a wicked looking hunting knife tied to it, the tip of which disappeared into her open mouth.  As the lighting panned lower it became clear each of her ankles were in heavy iron manacles. their dirty rust colour contrasting with her pale skin. Her feet were three feet from the floor and the chains pulled down to a floor mounted winch. Another pole was there too, jutting upwards. Again it was tipped with a knife, the tip of this one vanished between her legs. It was clear she was trembling.

"Time for some audience participation...."

Lisa selected four of the larger guys from the small group, stationing two at the winch operating the chains falling from Jean's ankles and the other two to a similar one attached to her wrists and neck by chains and a ceiling pulley.

"OK, legs take up the slack...Come on, don't be shy!"

The two guys looked at each other and after a few more moments hesitation heaved on the winch handles. The chain tightened further and there was a click as the mechanism stopped it moving back. 

"And arms ..." 

Jean groaned as her arms were pulled up, forcing the knife blade a little deeper into her mouth. Under Lisa's direction her legs were pulled again next. Two clicks this time. Jean's hips bucked a little as a half an inch more of the knife vanished between her legs.

"Interesting isn't it. What will be decided factor? Her throat sliced open from the inside ? Being impaled on a knife from below? Or simply being torn apart ? "

There was a feint sob as first one winch then the other was wound on, a click at a time. Jean's body was pulled taut, she had no chance of wriggling now. She seemed to be being stretched. More clicks. A cry of pain, a trickle of blood on her left thigh. Several people looked away

"Keep going you can't stop now" 

Impossibly each winch was wound on further and  further. The blades of both knives were barely visible, three quarters of each now inside the trembling Jean.

"Pull together ... heave...."

Both teams pulled at once. Jean tried to scream but it became a wet gurgle. Then there was a crack, like dry wood breaking underfoot. Several of the audience screamed. One woman passed out. Both pairs of guys took several steps back as the resistance they had been pulling against vanished.  Everything went dark.

After what seemed like a life time but was probably only a few seconds a red light illuminated the scene. Jean had been torn in two about the waist. Her top half had shot upwards to the ceiling while her lower half had sunk to its knees on the floor. Both poles had completed their impalement.

Lisa turned without a word and moved through the next doors
