The popular literary sleuth Nancy Drew is getting a new live-action television series on The CW this October, and the upcoming series' latest trailer shows its eponymous detective investigating a supernatural mystery.

After she and her friends witness a murder, Nancy begins looking into a ghost story involving a spectral woman, with more sinister clues surfacing as the case deepens.

Created as a pulp novel character by Edward Stratemeyer, the upcoming television adaptation is developed by Josh Schwartz, Stephanie Savage and Noga Landau. While the cast for the pilot had included Freddie Prinze, Jr. as Nancy's father Carson, the role has since been recast with Scott Wolf.

Principal photography on the first season began last month in Vancouver, with the Canadian coastline and cliffs featuring prominently in the latest trailer. Judging by the presence of the ghost seemingly stalking Nancy, the local ghost story may have a terrifying truth to it.

Nancy Drew premieres on October 9 at 9pm ET/PT on The CW. The series stars Kennedy McMann as Nancy Drew, Tunji Kasim, Maddison Jaizani, Scott Wolf, Riley Smith and Alex Saxon.
