Head Case

The man in the emergency room was not your typical head case. He ran out onto a highway and got hit by a truck. The doctors call him John Doe because he can't remember anything. His first visitor is a man who claims to be his brother, but once the two men are alone, all hell breaks loose.
"You can stop the amnesia routine," the visitor growls as he pulls a gun. "I know who you are and I know what you've done!" A shot is fired and the two men struggle - but John manages to escape.
But in Jay Bonansinga's Head Case, freedom isn't the same thing as safety. John's days are a hideous waking nightmare. And his nights are filled with flashes of his past - flashes filled with mutilated bodies and blood-splashed rooms. Suddenly, John is learning more about what he is than who he is. Looking for help, he finds an ally in the wounded beauty Jessie Bales, a tough-as-nails private investigator who is willing to help John find out who he really is and what's really going on.
But what she finds terrifies them both. She discovers a secret police file, a trail of bodies, and a madman's diary in John's own handwriting that chronicles a murderous rampage. Jessie can't believe that the man she has come to trust could be a killer. But no matter what her heart tells her, her head is screaming that the man and the monster are one and the same. And as Jessie gets closer to the truth, we learn that the final answers are more sinister than either John or Jessie dares imagine.
