The Vampire of Western Pennsylvania

Ace FBI Agent Sidney Braman slams against the most challenging case of his career: a bloodless body discovered in a burning house in rural northwest Pennsylvania. But what happened to the victim’s blood? Evidence points to dozens of mysterious, blood-emptying deaths occurring there. Vampire? A confirmed rationalist, Sidney is the last person in the world to be drawn in by a nonsensical legend. But as the bloodless corpses pile up, Sidney questions his own disbelief. More eerily, buried in the mysterious murderer's digital trail, he discovers the FBI's secret file detailing his own wife's brutal unsolved murder.
