Caroline tells Jane about the very mysterious disappearance and murder of Molly Bish. In the summer of 2000, 16-year-old Molly vanished in a matter of minutes from her job as a lifeguard at a small pond in Warren, Massachusetts. Her mother remembers seeing a creepy man staring at Molly the day before, but other than that, the clues are sparse. Although the subsequent years have produced quite a few suspects, the case remains unsolved.
