My daughter was left freezing and homeless in an alleyway. Her husband had secretly forged her signature, sold their home, and stolen my granddaughter to live in a luxury penthouse with his mistress. I didn’t scream or break down. I took my shattered daughter home, made one phone call, and drove to his high-rise building the next morning. When he confidently opened his penthouse door, what I had waiting for him would ensure he never saw sunlight as a free man again…

I heard footsteps behind me. Anna stood in the doorway, frowning. “Dad? What are you doing?”

I swung the heavy door open. The interior smelled of old paper and gun oil. Inside sat neatly organized accordion files, sealed manila envelopes, digital hard drives, bank record templates, court transcripts, a holstered Glock 19, and a gold badge wrapped in a leather wallet that I had not worn in twelve years.

Before my wife died, before I retreated to the quiet life of a pensioned widower, I had been the lead forensic fraud investigator for the state attorney’s office. I spent thirty years hunting white-collar predators. Men who wore bespoke suits and stole millions with the stroke of a pen. Men who ruined lives without ever getting their hands dirty.

Men exactly like Mark.

They had all smiled at me in the beginning. They thought they were smarter. They thought their money made them untouchable.
