Treasure in the Royal Tower is the fourth game in the Nancy Drew PC Adventure Series. It is based on Nancy Drew Mystery Stories #128: Treasure in the Royal Tower, and was released on July 24, 2001.

In this game, Nancy is snowed in at Wickford Castle when a rash of crimes happens in the castle. Learning a rumor that Marie Antoinette may have hidden a treasure in one of the imported towers, Nancy is convinced the two are connected, and begins hunting for the treasure.


Follow ancient clues to find Marie Antoinette's legendary secret!

You, as Nancy Drew, travel to Butter Ridge, Wisconsin, for a skiing vacation. The owner, Christi Lane, is a friend of Nancy's dad and has invited you to stay for awhile, but she is currently away on business. All is going well, but when a blizzard hits, you and the other guests are snowed in with a mystery. The castle's library has been vandalized and one of the guest's rooms has been robbed! Now you are trapped in a place that's as strange as its history. Wickford Castle is a riddle; full of dead-ends and detours that hint at a legend left behind by Marie Antoinette! Solve baffling puzzles, search concealed rooms, interview evasive suspects, and sidestep danger on the hunt for a secret that the doomed queen was desperate to hide!
