SUDDEN SHADOW Ryan Wilson is a Chicago Homicide Detective with a penchant for solving homicides with style and success. His solve rate is one of the best but his newest case is a puzzler. He is looking for a murderer that does not appear on the video tape of the murder scene and his only lead is an elusive thief that he hopes saw the killer. The case takes a strange twist when the killer strikes again with no apparent motive or connection to the first crime. Wilson relies on his partner Laura Nelson and his network of experts to help him find a link to the killer, but when he gets help from an unexpected source, he is reminded why people fear what might live in the shadows.
