Faster

John ran, his pursuer close behind. "Stop! " his pursuer shouted. "Security! Stop him, he has a knife!". John ran faster. A uniformed guard stood, blocking the way. "Help, it's not me, he's mad," John said as he dodged the guard, his accuser following. Faster. John saw a sharp glint in the blur behind him. Faster. "You! You killed me! You're not human!" he heard from behind. John ran. Past a baggage carousel, over a low railing, away from windows. His footsteps echoing on granite tiles, the crowd parting. John ran. His shadow now even closer. John glanced back, saw his pursuer had dropped to the floor, yet hadn't slowed down. He seemed even faster, loping on four legs. Or was it eight? John ran. Past the potted palm trees, up an escalator, along a high walkway. His legs stumbling, his chest heaving, vision blurry. John screamed as he felt two sharp points puncture his left heel. The venom burned in his blood.
