Kats moved slowly toward Epps. “I’m not with them,” he gestured to the men scattered on the ground. “I’m a friend of Dr. Turier. Do you remember Dr. Turier?” he said in his most calming voice. “I want to take you to him. We can make everything OK.” Kats wasn’t sure if the words were even registering, but the man didn’t move to attack or retreat. He was about to take another step forward when he heard a siren echo from up the street.

At the sound, Epps’ face twisted, and he surged forward toward Kats. Even though he was ready, Kats was shocked at how fast the man was. He pivoted to the side, like a matador with a charging bull, and as Epps passed by, Kats fired a fist into the man’s lower back, straight into the kidney. The strike should have disabled the man, but Epps barely grunted and whipped around with such speed and ferocity that Kats was immediately on the defensive. Epps shot his right fist toward Kat’s head. Instinctively, he raised his left arm to block the blow, saving himself at the cost of his arm. He rocked back, feeling like he’d been hit with a baseball bat, and his arm fell to the side, numb and lifeless. Kats had fought men who were stronger than he was. He’d also fought men who were faster. But he’d never fought someone stronger and faster. He dropped to one knee trying to gather himself as Epps turned again and charged.

As the wild-eyed man came at him, Kats knew his only chance was to redirect that savage energy, so as Epps raced forward, he welcomed him in and rolled backward, using his good arm to pull the man over him, actually accelerating his charge into the concrete wall behind him. The man met the wall with an audible grunt, and Kats had a moment to gather himself, but only a moment. Within seconds, Epps was again on his feet, facing Kats, seeming to seethe with power. Then from the garage entrance a flashing red light appeared, and a siren echoed up the walls. Epps spun toward the light and, seeing the approaching police car, bolted toward the open wall. Reaching the second-floor wall, he leaped over it in one smooth motion. Kats raced forward in time to see that Epps had landed safely and was already running down the alley toward a chain-link fence. Reaching the ten-foot fence, he appeared to run up the barrier in one long step and then was over and gone in one swift, near superhuman move. As Kats stood there, his chest heaving and his arm throbbing and hanging uselessly at his side, he wondered how he could possibly stop this living science experiment.
