Detective Maya Ellison had been working Internal Affairs for eighteen months. Long enough to know which officers were dirty and which ones were just tired. Daniel Mercer was both.
She had been following him for three weeks. The stops that always ended with “found” drugs. The cash that appeared in his locker after big arrests. The way he smiled at the women he pulled over when he thought no one was watching.
Tonight was supposed to be simple. She had parked her personal car on the shoulder, hazard lights on, waiting for him to take the bait. A broken taillight. A nervous look. The perfect excuse.
She hadn’t expected him to actually plant the bag.

The fentanyl was real. She had watched him take it from the evidence locker two days ago, signing it out under a case number that didn’t exist. He was getting bold. Or desperate.
When she showed him the badge, his face went through three expressions in under two seconds: confusion, recognition, then pure animal fear.
“Detective Ellison,” he said. The bag was still in his hand. He didn’t know what to do with it.
Maya kept the wallet open.
“You’ve been busy, Mercer. Three planted bags this month alone. Two of them on single mothers who couldn’t afford a lawyer. One on a kid who was just trying to get home from work.”
Mercer ‘s mouth opened. Closed.
The rain was soaking through his uniform shirt. He didn’t seem to notice.
“I can explain,” he started.
“No,” Maya said. “You really can’t.”
She took the bag from his hand. He let it go without resistance.
Behind them, another cruiser pulled up. Two officers Maya had hand-picked for this. They didn’t ask questions. They just cuffed Mercer and put him in the back seat like they had done it a hundred times before.
Mercer didn’t fight. He just stared at Maya through the rain-streaked window as they drove away.
The next morning, the news broke quietly. Officer Daniel Mercer, fifteen years on the force, placed on administrative leave pending investigation into evidence tampering and civil rights violations.
Maya sat in her office with the case file open. The bag of fentanyl was logged and sealed. The bodycam footage from her car and the backup unit was already uploaded.
She should have felt satisfied. This was the kind of case that made careers in IA.
Instead, she felt tired.
Because she knew Mercer wasn’t the only one. He was just the one stupid enough to try it on her.
Her phone rang. The captain.
“You did good work, Ellison. But you know how this goes. The union is already circling. It’ll be months before anything sticks.”
Maya looked at the photo on her desk. Her daughter, six years old, smiling in a soccer uniform.
“I know how it goes,” she said.
She hung up.
That afternoon, she drove to the house where one of Mercer’s victims lived. A single mother named Teresa Ruiz. Two kids. Worked double shifts at the hospital. Mercer had pulled her over for a broken headlight that wasn’t broken and “found” three grams of cocaine under her seat.
Teresa opened the door in scrubs, eyes wary.
Maya showed her badge.
“I’m Detective Ellison. Internal Affairs. I wanted you to know that the officer who stopped you last month is no longer on the street.”
Teresa didn’t smile. She just nodded once, like she had learned not to hope for too much.
“Is that supposed to make me feel safe?” she asked.
Maya didn’t lie.
“No. But it’s a start.”
She left her card.
On the drive home, Maya thought about the look on Mercer’s face when he realized who she was. The moment the power flipped. The moment he understood that the woman he thought was just another body to push around had been watching him the whole time.
She hoped it haunted him.
Because Maya Ellison had learned a long time ago that the badge only mattered if you were willing to use it on your own.
And she was.
