One note and her world is upended.
Following her aunt's death, Detective Sarah Brown is heartbroken personally and at a standstill professionally.
Critical evidence that Sarah possesses is somehow wiped from a USB stick nobody knows she has.
When she discovers those same files on her lieutenant's computer, it falls in with a growing list of evidence against him.
Unable to trust anyone on the force, Sarah is left to seek the truth on her own.
If it wasn't before, it's personal now.
The victims include members of her family and her former partner.
She's on the hit list, too.
