Nancy, Bess, and George visit an old inn and meet Asa Sidney, a distant relative of the cousins, on the day of his 100th birthday.
Nancy generously arranges an impromptu celebration for Mr. Sidney through the innkeeper and his wife.
During the party, she befriends the foster daughter of these caretakers and discovers Mr. Sidney is virtually a prisoner in his own mansion.
The young detective is further puzzled upon learning of the elderly man’s disappearing fortune.
Following Mr. Sidney’s sudden demise, Nancy searches the old inn for answers, but this quest and her new friendship with the young girl nearly cause her to lose Bess and George.
With only the sign of the twisted candles to guide her, Nancy uncovers hidden treasures, an amazing letter, and ends a long-standing family feud.
