"When Rick Shepherd, a physician, approaches his office on a busy Manhattan street, he finds police cars, an ambulance, and crime scene technicians. He soon learns a passerby was shot three times in the back, murdered at the front door to Rick's office. Later that evening while watching the local news, Rick and his fiancee, Jackie, see a photo of the victim--to their horror, the deceased looks identical to Rick. Two nights later, while making a house call in a Brooklyn apartment building, Rick's 64-year-old father is shot and killed in the exact same way. Detectives Art Nager and Liz Callaghan are assigned the case, and they launch an investigation. There are no clues leading to the perpetrator. Even more ominously, someone has been calling Rick and Jackie's apartment and hanging up. Whoever is targeting Rick must have murdered his father, and they now have Rick in their crosshairs. Nager and Callaghan seem to be making no progress with their investigation. Rick's quest for the truth draws him into a labyrinth of secrets, past tragedies, and the agonizing pain of lives shattered by a single event. Can he make it out before he meets the same fate as his father?"
