The Soul of Javier - S. A. Martin

"Jason Javier is obsessive-at times he could be abrasive-but he's relentless in his pursuit of the truth. Worse, he is being haunted by a crazed entity. Yet the disturbing psychological episodes paled beside his unyielding determination to uncover his father's killer."

A horrible discovery provides clues into his councilman father's mysterious disappearance, sending the news journalist barreling into an investigation that's being tainted by a crime syndicate. A cabal of dangerous men who are desperate to remain hidden, and a supernatural entity with secrets it also doesn't want unmasked.
