The Trophy Taker: DC Charlotte Stafford, Book 2

He keeps each one floating in formaldehyde to prevent rotting. Each finger denotes a victim, their heart ripped out and replaced by symbols of their treachery. He admires his trophies weekly; to him each one of them is guilty.

DC 'Charlie' Stafford is already investigating a series of escalating racist attacks, and it now seems she has a vicious serial killer on her patch. All the while he's watching, waiting...and counting.
