WARNING: This article contains spoilers for Nancy Drew episode 9. Read at your own risk.

Nancy Drew episode 9 will arrive on The CW next week and this will serve as the winter finale, with the title "The Hidden Staircase." Since the episode will be the final one this year, most viewers of the freshman series are wondering whether all the mysteries will be solved or not.

In the Nancy Drew episode 9, Nancy needs to search for clues from both the living and the dead so she could solve the mysterious murder of Tiffany Hudson. Lucy is now dead and the case might be handed over to state authorities. The titular character needs to do everything she can to find answers in order to protect her father.

Since Nancy Drew episode 9 serves as the winter finale, viewers should expect some twists and turns, big revelations, as well as a possible huge cliffhanger. Based on the synopsis of the upcoming episode, Nancy needs to deal with some professional and personal challenges. She and the Drew Crew will desperately search for George's missing sister, Ted.

Ted has been communicating with an unknown spirit and has been kidnapped. The kidnapping incident turns out to be something frightening as it is similar to other previous disappearances. One of the questions now in the winter finale is whether or not Ted's kidnapping is connected to the mysteries Nancy has been trying to solve the entire season.

As for what else is coming in Nancy Drew episode 9, the titular character failed to solve a present-day mystery, so she was forced to revisit a traumatic incident from her past. She needs to recall some traumatic events happened in her past in order to get some answers.

Nancy will eventually reconnect with her father, who's the possible suspect behind Lucy's death. Because of the new finding, she comes face to face with him, but they might be separated forever due to the investigation progress. It looks like not all mysteries will be solved in the winter finale, as the series may likely leave some major cliffhanger -- particularly with Nancy and her father.

Nancy Drew episode 9 will air on Wednesday, Dec. 11, on The CW. The series stars Kennedy McMann as Nancy Drew, Scott Wolf as Carson Drew, Leah Lewis as George, Riley Smith as Ryan Hudson, Maddison Jaizani as Bess, Al Saxon as Ace, and Tunji Kasim as Ned.
