At 6:17 on a rainy Monday morning, Daniel Mercer was scrubbing dried blood from the floor of a fighting cage.
The gym was empty except for the steady hum of fluorescent lights, the hiss of rain against the windows, and the squeak of his mop moving across the black rubber mats. A forgotten hand wrap lay beneath the lowest row of seats. Someone had left a half-empty bottle of electrolyte drink beside the punching bags. The smell of sweat, disinfectant, and old leather hung in the air.
Daniel collected the bottle, dropped it into a trash bag, and returned to the stain.
Daniel had worked at Blackstone Combat Academy for eleven months. He arrived before sunrise, cleaned the training rooms, repaired loose equipment, emptied trash cans, and left after the last students went home. He rarely spoke unless someone addressed him. He never asked about the fights advertised on the gym's enormous promotional screens. And when students practiced combinations beside him, he kept his eyes on his work.
At 6:32, the front door swung open.
"Morning, everybody!"
The voice belonged to Ethan Caldwell, although nobody else had arrived to hear him.
Ethan was twenty-four, the only son of a wealthy real estate developer, and the reigning amateur champion of Blackstone's elite competition program. His face appeared on banners throughout the gym. His name was printed on limited-edition training gloves. His father had donated enough money to renovate the facility's main arena, and Ethan never allowed anyone to forget it.
He wore a designer tracksuit, carried a leather gym bag, and had the relaxed smile of someone who had spent his entire life being told he was destined for greatness.
Behind him came Marcus Reed, his training partner and closest friend.
"You're early," Marcus observed.
"Champions don't sleep in."
"You were at a nightclub until two."
"Champions also know how to manage recovery."
They crossed the reception area, passing Daniel without acknowledging him.
Ethan stopped near the cage and looked down at the damp patch Daniel was cleaning.
"Hey, man. You're missing a spot."
Daniel moved the mop across the floor once more.
"Thanks," he replied.
Ethan waited, apparently expecting more. An apology, perhaps. Or an explanation.
"Did you hear me?"
"I heard you."
"Then why aren't you answering properly?"
Daniel lifted the mop and placed it in the bucket.
"What would you like me to say?"
"I'd like you to remember who's paying your salary."
"Your father pays the gym," Daniel said. "The gym pays me."
Marcus turned away to conceal his grin.
Ethan stepped closer.
"You're funny."
"Not usually."
"What's your name?"
"Daniel."
"Daniel what?"
"Mercer."
Ethan repeated the surname as though testing whether it meant anything.
He glanced at Daniel's hands. The knuckles were thick, with pale lines crossing the skin. His left wrist bore a faded mark that looked almost like the outline of an old burn.
"You ever fight, Daniel?"
Daniel picked up the bucket.
"Not anymore."
"Not anymore?" He laughed. "What does that mean? You used to get into bar fights?"
"No."
"Boxing? Wrestling? Something like that?"
Daniel walked toward the utility closet.
"Come on. Don't be mysterious. I'm trying to have a conversation."
Daniel stopped at the doorway.
"Then have one with somebody who wants to talk."
For a second, Ethan's expression emptied of amusement. He wasn't accustomed to being dismissed, particularly by someone wearing a work uniform.
"See you around, Daniel Mercer."
Daniel entered the closet and shut the door.
"Man, leave him alone."
"Why?"
"Because he's cleaning floors. What do you want from him?"
"Respect."
"From the janitor?"
Ethan looked toward the closed door.
"Exactly."
He had no idea that Daniel had heard every word.
Inside the closet, Daniel rested one hand against a shelf filled with cleaning supplies. He closed his eyes and took a slow breath.
A man's voice through a loudspeaker.
Daniel opened his eyes immediately.
He reached into his pocket and touched a small silver ring attached to his key chain.
It had belonged to his younger brother, Michael.
Daniel had carried it for six years.
"Not today," he whispered.
At eight o'clock, the gym filled with students. Trainers shouted instructions. Gloves slapped against pads. Music pulsed through the speakers.
Daniel moved among them unnoticed, wiping benches and replacing paper towels.
Near the main arena, Ethan began a demonstration for a group of prospective members. He moved beautifully when he wanted to. Fast hands, powerful kicks, an instinct for timing that could not be purchased with his father's money.
When a younger trainee failed to block a combination, Ethan struck him harder than necessary.
"Again," Ethan ordered.
