P. J. Parrish
In both her bodies
In 1995 two sisters, Kristy and Kelly Montee, originally from Detroit but then living in two different southern states, combined to become one mystery writer, P. J. Parrish. As Parrish, they (or she?) created the essential ingredient of any mystery: the inimitable, unforgettable cop or private eye. In this case, it's Louis Kincaid.
