The same idea seemed to occur to the gunman. "You tell those bastards to stay away from us," he shouted. "Anybody tries to mess with us, they gotta go through one of these kids to do it." Within the house, a woman cried out. Hadley didn't realize the man had left his defensive position at the front window until the chief shouted, "Knox! What's he doing in there?"

She scrambled to her feet and peered into the window she had been crouched beneath. She got a beautiful view of the front hallway and the stairs. Useless. She covered the eight feet to the next window in two long strides. The sill was just low enough for her to see into a room in chaos, children scattering, a teenager clutching an infant, a woman struggling with the man as he yanked a little boy off his feet.

"He's holding a kid," Hadley yelled. "He's-oh, shit, no!" She watched, helpless, as the man clubbed the woman in the face with the butt of his gun. The woman dropped to the floor.

"Are there other shooters?" the chief yelled.

"I can't tell!" she screamed. "Maybe in the front-"

The man holding the squirming child turned toward the window, aiming the revolver at Hadley. She ducked and covered just in time. The window shattered. Shards of glass sliced into her hands, stabbed the back of her uniform, caught in her hair.

The chief was yelling for her and Flynn to get to the back door. She heard the muffled thud of footsteps against grass and then Flynn was beside her. He tossed her a Kevlar vest identical to the one he was wearing.
