In the early days of telephones a party line was one phone connection shared by several households. Then, before the internet, a party line was like a chat room by telephone where people talked instead of using the computer. Now there’s one in Mark’s town and he’s addicted to it. When you’re anonymous and invisible it’s a lot easier to talk to girls…or to eavesdrop on them. It’s an expensive habit and Mark is grounded from doing it, but he still hasn’t stopped. Local girls have been disappearing and Mark begins to suspect the disappearances are connected to the Line, maybe to the oily-voiced guy who keeps trying to get personal information from girls. Everybody lies on the Line and no one believes Mark, so he begins his own investigation. Now it’s a race between Mark and the unknown kidnapper and if Mark doesn’t win, someone he’s beginning to care about very much could be next.
