When the city bleeds, only two detectives are ruthless enough to stop the flood.

Detectives Lee Krauser and Michelle Slater don't play by the rules-they break them to shatter the bones of the criminals who prey on the innocent. Krauser, a towering force of muscle and rage, is a legend on the streets of Indianapolis. Slater, sharp-tongued and fearless, clawed her way out of the gang unit with fists and firepower. Together, they form an unbreakable partnership forged in blood and loyalty.

But their toughest case yet has a name whispered in fear: The Ripper. A phantom with no identity, no pattern, and no mercy. Clad in a yellow raincoat and armed with a fire axe, he butchers without warning-and vanishes like smoke. As the body count rises, the city turns into a hunting ground where no one is safe.

For Krauser, it's personal. The Ripper has eyes on his family-and he's running out of time.

To stop a killer with no past, the Lethal Detectives will have to confront their own. What begins as a manhunt spirals into a war-and not everyone will survive.
