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.
It's increasingly apparent that someone has more than a passing interest
in shutting down the library. But who--or what--is responsible? And why?
