Blindside

The mayor of New York has a daughter who's missing and in danger. Detective Michael Bennett has a son who's in prison. The two strike a deal.
Bennett and the mayor have always had a tense relationship, but now the mayor sees in Bennett a discreet investigator with family worries of his own.
Just one father helping another.
The detective leaps into the case and sources lead him to a homicide in the Bronx. The victim has ties to a sophisticated hacking operation and also to the mayor's missing daughter, Natalie, a twenty-one-year-old computer prodigy. The murder is part of a serial killing spree, one with national security implications. And suddenly Bennett is at the center of a dangerous triangle anchored by NYPD, FBI, and a transnational criminal organization.
Michael Bennett has always been an honorable man, but sometimes—when the lives of innocents are at stake honor has to take a back seat. Survival comes first.
"I DID EVERYTHING I could to distract Lucille Evans from noticing the
bloody footprint. A responding patrol officer had tracked the blood into the hallway. One look at the scene inside and the veteran needed to run into the street. I didn’t blame him one bit. The forensics people were in the small, two-bedroom apartment on the third floor of this building on 146th Street near Willis Avenue in the Bronx. The scene was so horrendous that the local detectives had called me to help even though it wasn’t technically considered part of Manhattan North Homicide’s usual territory. Two of the local detectives had lost it. It
happens. It’s happened to me over the years. I lost it once at the scene of a murdered girl. Her stepfather had bashed her head in for crying because she was hungry. She reminded me of my own Shawna, staring up through blood splatters. When I heard her stepfather in the other room, talking with detectives, I snapped. It almost felt like another being possessed me. I burst into the room, ready to kill. Only the fact that my partner at the time, Gail Nodding, was as tough as nails and shoved me back out the door had kept me from killing the creep."
