The shadow killer

"It's Father's Day weekend, and it looks like some of the well-intentioned wisdom that Charlie D dispenses on his late-night radio call-in show might blow up in his face. One young listener seems intent on killing his father and the rest of his family. Unfortunately, no one knows where he is. Time is running out, until Charlie's own long-estranged father enters the picture."--P. [4] of cover.
