The Concrete Kiss by David Grace
Detective Ned Danes had the lucky job of cold cases. Those crimes that were never solved, with so little to go on, but had families that needed closure and to know the truth.
FBI Agent Phillip Abbott had seen a lot in his day, but the horrific crimes of a family serial killer ripped his heart when it happened to a family with an autistic girl named Jessica. When her family is murdered, Phillip and his wife adopt her.
So when they teamed up to solve the serial killer murders, and went a touch out of bounds in order to try to capture him, you could not have asked for a better team. This killer was cold, calculated and had no remorse for his victims, it was just a job he was paid to do.
While they are on the hunt for the killer, running as a separate side line was a cold case of abducted girls. Little clues to help solve this case.
What could have been split into two books, maybe one as a number two in a series, was crammed into one book. The majority is based on the serial killer, with small references to the abducted and raped girls case. While the characters will keep you interested, and it is a thriller to be sure, it probably might have been better staying with one of the story lines rather than try to merge them together.
