Not sure how much you wanted.
Marcy Blackbourne joined the police force at the tender age of eighteen. She served for a scant two years before quitting due to a hatred of the system. She turned to private work as a PI not long after. She wasn’t thrilled with her new job, but it paid the bills, even if most of her cases were looking into cheating spouses and the like.
She tends to dress simply, and usually carries a small pistol, pepper spray, handcuffs, Taser, and Maglite. She knows enough self-defence and hand-to-hand combat to get by, but prefers to keep her distance.
