Cree Black is a psychologist turned parapsychologist hunting some ghosts haunting a stately mansion in New Orleans. It was a darn good ghost story populated by interesting characters. City of Masks takes a scientific approach to ghost hunting with a little voodoo, espionage and murder thrown in for good measure. I found out this is the first in a series of “Cree Black” books, each set in a different city and filled with that cities culture and beliefs. I will definitely be looking for more books by Daniel Hecht.
