The Reaper's Game

"IS IT MURDER FROM BEYOND THE GRAVE . . . OR THE FINAL RUSE OF A TWISTED SERIAL KILLER?
Three years ago, a deranged murderer dubbed the Halloween Killer butchered half a dozen people in New Orleans. He was caught and sentenced to die. Just before his execution, the Halloween Killer vowed to take revenge on the district attorney who put him behind bars. Less than a week after the lethal injection, Sebastian Gichaud, a wealthy playboy grieving over the death of his mother, throws on a black cloak and hacks the prosecutor to death with a giant scythe. Not only did Sebastian appear to be fulfilling the serial killer’s last wish -- he claimed that he was the Halloween Killer. Now, as the anniversary of the grisly murder approaches, Sebastian is facing trial. No one will touch the case. In a desperate attempt to save his son, Sebastian’s father hires Viktor Radek, professor of religious phenomenology, to investigate."
