Pulse (Unabridged‪)‬

The killer's depravity is insatiable. What he does to his victims is unthinkable. Homicide detective turned P.I. Frank Quinn has seen this M.O. before. A demented ritual, it's the work of Daniel Danielle - a notorious serial killer who blurs the line between male and female, human and monster. Danielle disappeared ten years ago. Is a copy cat repeating the crimes? Or has Danielle made a deadly return? Either way, this time the killing won't stop.
