This was not ordinary barbed wire. It had a tempered-steel core of memory wire, metal that no matter how it was twisted or coiled would return to its original shape when the restraints were removed. Where ordinary wire would have lain in a heaped tangle this fought to regain its remembered form, moving haltingly like a blind beast as the strains and stresses were relieved, uncoiling and stretching along the street. Policemen wearing heavy gloves grabbed the ends and guided it in the right direction to form a barrier down the middle of the road. Two expanding coils met and fought a mindless battle, locking together and climbing into the air only to fall and struggle again and squirm on in a writhing union. When the last strand stopped scratching across the pavement the street was blocked by a yard-high and a yard-wide wall of spiked wire.

But the trouble wasn’t over; people were still pushing in from the south along the streets that had not yet been sealed off by the wire. For the moment it was a screaming, pushing impasse because, though more wire would stop the influx, in order to drop the wire the crowd had to be pushed back and a clear space made. The police were shoved back and forth in the face of the surging mob and above their heads the copters buzzed about like angry bees.

A sudden exploding crash was followed by shrill screams. The pressure of the jammed bodies had burst one of the plate-glass show windows of Klein’s and soft flesh was being jammed onto the knives of glass; there was blood and moans of pain. Andy fought his way against the tide toward the window; a woman with staring eyes and blood running from an open gash on her forehead bumped into him, then was carried away.
