Pérez’s jaw dropped as he looked up at her high heels and ankles. He crawled out from under the desk and turned questioningly to his partner. Thorne didn't hesitate. He took one swift stride from behind, clamped a hand tightly over her mouth, and pulled her back into the room, disregarding her wildly flailing legs and frantic attempts to claw his hands away. He shut the door with a backward thrust of his foot. "What do we do now?" Pérez whined. "Observe." Thorne spoke calmly, as would a professor demonstrating a familiar operation to a beginner. Using both hands, he briskly snapped her neck. She stopped struggling.
