In the book “Nancy Drew and the Ghost of Blackwood Hall,” the legendary detective takes on a new case. The widow Mrs. Putney turns to Nancy for help. She is troubled by the ghost of her dead husband, who asks her to bury a box of family jewels in the forest. It is done! But when Mrs. Putney realized her mistake, it was too late: the jewelry was stolen from the box, and fakes were put in their place... Not believing in the stories about ghosts, Nancy uses her intuition and common sense and tries to get on the trail of the thieves. Circumstances lead her to the ancient mansion Blackwood Hall, where spiritualistic seance rituals are held. It turns out that these sessions are attended by many residents of the town, including Mrs. Putney. Trying to draw a parallel between sessions of spiritualism and a series of mysterious events associated with extortion of money and valuables, Nancy Drew receives more and more messages “from the other world”: do not meddle in this matter, otherwise it will be worse... For middle school age.
