Biography[]
Over fifty years ago before the events of the book, Tom Rotwell and Marissa Fittes rose to fame through their exploits when "the Problem" occurred. They developed the standards in dealing with ghosts including the use of rapiers. Sometime later, the two separated and the first two agencies, Fittes agency and Rottwell agency, were started.
