He hunts serial killers. He’s in bed with one.

Special Agent Leo Lawrence has made a career out of catching the worst of the worst. But over the past year, someone’s been beating him to the punch—a vigilante known only by the codename “The Green Cleaner”, who eliminates serial killers before law enforcement can catch them.

When Leo’s domineering sister asks him to look after her soft-spoken fiancé, Binqing Li, a Chinese student new to the U.S., Leo doesn’t think twice (lest he stoke her fury). But what starts as reluctant guardianship quickly turns into an unsettling, magnetic bond that has Leo teetering on the line of immorality.

Meanwhile, his increasingly intimate encounters with the Cleaner blur the line between the hunter and the hunted. He’s repelled by the killer’s methods, yet fascinated by the mind behind them. Caught in a web of obsession, desire, and secrecy, he begins to wonder: can he change the man behind the masks, or is he already too far gone?

Dark, seductive, and razor-sharp, The Killer of Killers is a tale of vengeance, justice, and the thin line between hero and villain.
