Whoever ghostwrites these books must have the time of their lives. They get to put whatever they want on paper and will never be held accountable for it, no matter how ridiculous it is.
In this one, Nancy is called to a girl's boarding school to investigate mysterious threats from someone called "The Black Cat." Bess and George help a lot in this one too. Multiple students have been targeted, plus one teacher, and there is a variety of suspects. One girl's hair was cut off in the middle of the night, another had tar on her lucky athletic shoes, an essay is wiped from a top student's computer, a social outcast is humiliated in front of the "cool girls" etc. etc. Nancy herself is nearly killed at least twice.
(This is one of those mysteries where I get frustrated with how little progress Nancy makes. She follows her suspects around, but never when it's the most important, and she never reports half the stuff she learns to people who could actually do something with the information (i.e. the headmistress or the police.) Like, Nancy, don't you want to tell someone you were locked in a refrigerator?!)
The stakes are raised when the teacher, Ms. Friedlander, is kidnapped for ransom money, and a student named Lila and eventually Bess mysteriously vanish. I'd like to point out this is the third ND book I've read where Bess has been kidnapped. While snooping in Lila's room, Nancy catches a glimpse of the culprit: "A black-cloaked figure in a huge cat mask with red eyes and vampire teeth loomed before her."
So yeah. Not only is the culprit using a black cat as a mascot, they are also dressing up as one as a disguise. Now that's what I call commitment.
The ending, as it turns out, actually surprised me for once: the culprit is Ms. Friedlander herself! After snooping in her house, Nancy finds a file on her computer titled "Scooter's Revenge," which somehow leads her to discover that Scooter was her black cat who tragically passed away, along with her parents, in a car accident. It is later revealed that Lila's father was a stockbroker who gave Ms. Friedlander's father some bad investment advice, which then caused him to develop some disorder where he fainted all the time, which led to the fatal car crash. That...is pretty convoluted. So Ms. Friendlander, in the depths of despair, became a teacher at the boarding school where Lila was a student so that she could kidnap her, get ransom money from her rich family and complete her revenge. Pretty convenient she had teaching credentials, eh?
Friendlander is caught when she picks up the ransom money in the graveyard. Nancy gives chase, but Friedlander menaces Nancy with a knife and almost runs her off a cliff. Luckily, she is able to swing herself up into a tree and Friendlander almost tumbles into the chasm below, nearly dragging Nancy with her, until George, Bess, and Lila all show up to save the day. Turns out Bess and Lila were locked in the mausoleum, where George found them. Bess is extremely chill that she was just saved from abduction, even joking about Friendlander's choice of desserts (soggy graham crackers.) She's been around the block a few times with this kidnapping thing.
Friendlander is rather unrepentant as she confesses her evil plot. "Yes, but I had fun," Ms. Friedlander said gleefully. "I liked upsetting people, because my life had been ruined. I wanted to make people miserable like me." Are we sure she is also not a teenager in disguise?
Other than the ridiculousness, I liked that this one had a coherent plot, that there were several developments in the mystery, the suspects were clear and the ending legitimately surprised me. The PC game had a lot of material to work with (even the Edgar Allan Poe subplot is in there!) and I can see how this made it easier for them to create a story with one of the stronger plots of all the games.
P.S. This is the third book I've read where Nancy mentions she is ready to bust to out some karate moves. Can somebody please direct me to the book where Nancy first becomes a karate master? It sounds like it's the most important book of the series.
