The first book introduces us to Mercedes Masterson just as she’s quitting her job as an agent with the State Bureau of Investigations to start her own private investigative firm. Also at that moment, a serial killer starts up his career.

Meet Mercedes Masterson: A private investigator who marches to the beat of her own grim drummer. She is hardnosed, keen eyed, and doesn’t take crap from anyone, except her own personal demons.
