The Twins

What would it take to break a person, to take their humanity? At 13, they'd survived a living nightmare at the hands of two vicious home invaders. Three years later, they've become living nightmares by causing the largest manhunt in New York city's history.

These were the words that the renowned psychologist Dr. Susan Patterson had reluctantly spoken to Detective Iris Williams and her partner Annette Toni. Their topic of discussion: 16-year-old Stacey and Jannifer McHill. A few weeks after Iris and Toni's horrific confrontation with the twins - where Iris was forced to shoot and kill Jannifer - Stacey McHill was sent to a new facility for the criminally insane.

It's been three months since Detective Iris Williams has been back to work. She has been on an extended medical leave, battling depression after she'd dropped the ball on the biggest case of her career - the apprehension of the 17-year-old serial killer, Stacey McHill. But instead of seeking treatment for her depression, Iris has been roaming the streets of New York City. The city's streets now haunt Iris, and paranoia has become her constant companion. The captain of the Double 0 precinct has placed Iris and Toni on desk duty, calling Iris an embarrassment to the department.

He was left to die, in the steaming jungles of Vietnam, by his commanding officer and the rest of his battalion back in 1975....they shouldn't have done that. Forty years later. Homicide Detective Iris Williams and her partner Detective, Annette Toni, are assigned to a case where the victims are left in the most bizarre manner. The killer's hiding place is somewhere in the abandoned subway tunnels under New York City. The media is calling him, The Piggyback Killer.

Homicide Detective Iris Williams and her partner, Detective Annette, are assigned to a case so baffling that it will leave them dumbfounded. In the meantime, a storm - more powerful than Hurricane Sandy - is headed toward the East Coast. Will Detectives Williams and Toni be able to unravel the perplexing murders that plagued the city, or will the perpetrator disappear with the storm?
