If you liked "Into the Dark" or "The Last Time She Saw Him" you will love the newest novel Significant Other from the author of Cause and Effect. The noose is tightening around the throat of Detective Scagleon as he runs face first into a conflict with the Russian Mafia, and the Mexican Cartel. When he is called by the lead detective from New Orleans for help to consult on a mirror image copycat serial killer mimicking the serial killer Dr. Libby McMan that he hunted down more than five years ago, and realized while he was standing in the room watching her being executed for her crimes that he had accidentally fallen in love with this brutal killer. The twist and turns leave him boiling in a pot of serial killers, mafia and dirty cops.
