In a city of eight million people, Alucard only cares about one: the killer.

He doesn't need forensic labs or DNA kits. He has the bloodline of Dracula and a sense of smell that can track a lie from a mile away. But being a vampire on the police force has its rules:

Never let the sun catch you.

Only feed on the guilty.

Never let your partner see your eyes turn red.

When a rogue vampire starts leaving a trail of bodies, Alucard's corporate-queen cousin, Carmela, demands he clean up the mess. But as the cases get darker and his partner, Anne, starts noticing the "glitches" in her memory, Alucard realizes that some secrets are too bloody to stay buried.

Elementary, my dear Watson. Monsters are real. And I'm the one wearing the badge.
