A psychological thriller where the killer is always one step ahead and hiding in plain sight. Nobody hears the killer enter. There are no broken locks, no shattered glass, no signs of struggle. Every victim is found lying peacefully, as if they simply drifted away in their sleep... except for the missing body part, carefully taken with surgical precision and their slit throats. With fear spreading faster than answers and no forensic trace to follow, Detective Dwight Cook and his team race against a predator who never forces entry, never wakes a soul, and never leaves without taking something. Everyone locks their doors at night... but the Locksmith doesn't need permission to come in.
