The Detective's Shadow Empire. A Decorated Cop's Double Life Ruling the City's Underworld (en Inglés) - J. R. Walton

By day, Detective Marcus Brennan is the city's most decorated cop. By night, he's Sentinel-the criminal mastermind running the empire he's sworn to destroy.

For fifteen years, Marcus has lived two lives with flawless precision. He solves murders while ordering hits. He mentors rookies while corrupting witnesses. He accepts medals while laundering millions. His double identity is so perfect that even his wife doesn't suspect the truth.

Then the department assigns him a protégé.

Detective Riley Chen is everything Marcus used to be: brilliant, incorruptible, and dangerously idealistic. She sees patterns others miss. She asks questions that shouldn't be asked. And when she starts investigating cases that connect to Marcus's shadow empire, she threatens to expose fifteen years of carefully constructed lies.

Marcus has three choices: corrupt her, eliminate her, or let her destroy everything he's built.

But Riley won't be bought. She won't be intimidated. And she won't stop digging until she uncovers the truth-even if that truth shatters her faith in the one mentor she trusts.

As Riley's investigation closes in and Marcus's criminal organization turns against him, he faces an impossible decision: protect his empire or save his soul. Because in a world built on lies, the truth doesn't set you free.

It destroys you.
