After fifteen years in solitary confinement, Victor Thomas Janko -- the notorious Baby Carriage Killer -- is eligible for parole. Determining his release is Dr. David Rothberg, the new prison psychiatrist. Struggling with demons of his own, David slips into the psychological quicksand of this disturbed inmate, his manipulative girlfriend, and a brutal guard.

As he fights to atone for a mistake made earlier in his career, his passion for justice turns him from psychiatrist to detective.

But the question remains -- is he as smart as he needs to be to see the hidden truth?

The first Dr. David Rothberg novel is a high-voltage, twisty psychological thriller that will keep you guessing until the very last page.
