The Blue Lady of Coffin Hall:

Ned and Nancy track down a ghostly saboteur in the twenty-third book in the Nancy Drew Diaries series, a fresh approach to a classic series.

Nancy and Ned are visiting Coffin Hall, an estate turned rare books library, doing research on the library’s rumored ghost for an episode of the NedTalks podcast when a fire breaks out in the records room. One of the library’s security guards accuses Ned of arson—after all, he was the only one in the room when the fire started—but Ned swears it wasn’t him. He was trying to stop the fire. He tells Nancy he saw a lady in blue right before the incident, and thinks it was Henrietta Coffin, the ghost of Coffin Hall!

Nancy is confident her boyfriend is innocent, and she’s determined to identify the real culprit, though she’s pretty sure it wasn’t of the paranormal sort. When she investigates further, she learns that the fire was just the latest in a string of recent strange and inexplicable incidents plaguing Coffin Hall.

Captain Stone’s Revenge:

Nancy’s sailing trip to Vermont turns into a hunt for a ghostly saboteur’s lost treasure in the twenty-fourth book in the Nancy Drew Diaries, a fresh approach to a classic series.

When a family friend, Grace, opens a sailing club on Lake Champlain at the former site of the Gemstone Islands Resort, Nancy, Bess, and George are invited to enjoy a few days of boating before the club’s official grand opening. But when they arrive, they learn there have been some strange things happening on the property, from missing items to holes dug all over the yard. Is someone trying to sabotage the club, and could it have anything to do with the fire that destroyed the old resort twenty years ago?

As Nancy tries to pry information from the tight-lipped locals, all clues lead back to Captain Richard Stone, the enigmatic Revolutionary War–era pirate whose tavern once stood on the same site as the resort and sailing club. Legend has it that Captain Stone’s ghost still haunts the property, guarding the treasure he buried there. But it isn’t a ghost that punches a hole in Nancy’s sailboat, leaving her and the girls to sink in the middle of the lake when an unexpected summer storm rolls in.

Unraveling the mystery of Captain Stone’s treasure will be the key to finding out who’s been sabotaging Grace’s club. But first, Nancy and her friends will have to make it back to shore in one piece…
