This is a terrifically good, terrifically scary serial-killer story set in San Francisco and Los Angeles. The world of SHADOW MAN arrives fully formed, as if we're at the second or third installment of a well-established series. The novel's protagonist, FBI agent Smoky Barrett, is scarred and traumatized at the outset from a past encounter with a murderous psychopath -- a run-in that resulted in the deaths of her husband and young daughter. Now she has another nut on her hands.
