For fifteen years, I trained Marines to turn nothing but their bare hands into deadly weapons. I was the master hand-to-hand combat instructor for Force Recon and MARSOC Raiders at Camp Lejeune.

Dustin backed into the corner of the octagon, his chest heaving as if he had just run a marathon. His hands were raised in a weak defensive guard, but his fingers were trembling.

"Stay back!" Dustin yelled, his voice cracking. "My uncle is Frank Miller! You touch me, and his crew will wipe you and your family off the face of the earth!"

"Your uncle isn't in this cage," I said, walking toward him with deliberate, measured steps. "Your crew is unconscious on the floor. Right now, it's just you and the father of the girl you put in the hospital."

Dustin snapped. He threw a lightning-fast combination—a jab-cross-hook that had knocked out dozens of amateur fighters. It was fast, but it lacked the killer intention of a man fighting for his life.

I slipped the jab, parried the cross, and let the hook slide harmlessly over my head. I didn't strike back immediately. I wanted him to feel the absolute hopelessness of his position.

"Faster," I said coldly.

Dustin screamed in frustration and unleashed a barrage of wild, frantic punches. I dodged every single one, moving with effortless efficiency, stepping around his balance line, controlling the distance as if I were guiding a novice recruit through a drill.

"Is this what you used on Evelyn?" I asked, my voice cutting through his heavy panting. "Did you feel brave hitting someone who couldn't hit back?"

"Shut up!" he screamed, throwing a desperate spinning back-fist.

I caught his wrist mid-spin. I twisted his arm behind his back, locking his shoulder joint until the cartilage groaned under the immense strain. I pushed him face-first into the metal chain-link wall of the cage.

Dustin shrieked as his face was pressed against the rough steel mesh. "Stop! Please! I'm sorry!"

"You're not sorry you hit her," I whispered into his ear, my thumb pressing firmly into the sensitive nerve bundle below his jawline, sending sharp spikes of agony through his nervous system. "You're just sorry you got caught by her father."

"I'll leave her alone! I swear to God I'll never go near her again!" he sobbed, tears cutting clean lines through the dirt and sweat on his cheeks.

"I know you won't," I said. "Because if you ever look in her direction again, I won't use my hands. I'll use the skills I saved for real monsters."

I released his wrist and drove a hard, controlled strike to his liver. Dustin collapsed onto his knees, gasping for oxygen, his body curling into a tight fetal position on the canvas.

I stood over him for a moment, letting the cold adrenaline slowly recede. I pulled a clean handkerchief from my pocket, wiped the sweat from my brow, and unrolled the athletic tape from my hands, tossing it onto his writhing body.

I walked out of the cage, unlocked the front doors of the gym, and stepped out into the cool evening rain.

My cell phone buzzed in my pocket. It was Eleanor.

"Mark?" she asked, her voice tight with panic. "Where are you? The doctors just finished Evelyn's CT scan. She's awake."

"I'm on my way to the hospital, sweetheart," I said, my tone completely returning to the gentle father she knew. "Is she okay?"

"She's stable, but Mark... Dustin's uncle, Frank Miller, just showed up at the hospital with two of his men. They're standing outside her room right now."
