A fun little mystery. It has been YEARS since I last read a Nancy Drew book and it was great to read this story. I liked the treasure hunt aspect and, of course, Nancy and her friends were great characters.

A very strong entry. Nice characters, nice plot, a few exotic locales, Mr. Drew is very good, as usual, and the illustrations of Nancy some of the best, the young sleuth rarely looking better, save the cover illustration, which doesn't look like Nancy at all.

A 'okay' mystery that gives us some interesting bits of history and scenes in the Florida Keys.

What I found fascinating was how despite not being allowed to do anything too action-packed, because she's 'just a girl', or having any actual authority, Nancy is in charge of everyone and everything and seems to keep all the men in her thrall.

Her relationship with Ned has a weird almost sexual tension to it that is worthy of the 'Sex in the city' girls.

Calling this book a " good book " doesn't do it justice . The author , Carolyn Keene , keeps you in suspense throughout the WHOLE book . Nancy Drew , an amateur detective , is a mystery-solving , butt-kicking , 18 year old daughter of a criminal lawyer . These books are going to change the outlook of everything you take upon in the future . " The Clue of the Black Keys" is an original literature piece that keeps you on the edge of your seat . " Oh my gosh , they capture her " and " Plot twist " ...more

I love Nancy Drew. I picked this book off my shelf out of nostalgia. Also, after reading Girl Sleuth, I have a new appreciation for the books. And anyway, who wouldn't love a book that uses the word rumpus?

Still in that reliving childhood phase, this time mine and my mother's. This is one of her old Nancy Drew books that we found in one of my dad's storage buildings a while ago. Having grown up with the Hardy Boys, I wanted to also read some of Ms. Drew's adventures. They are just as fun.

This one takes Nancy on a trip to find ancient treasure and dastardly villains while on the search for a missing professor. There is danger at every turn, but our spunky young detective will not be swayed from her

The Clue of the Black Keys is a children's story by Carolyn Keene (pseudonym) and the 28th book in the Nancy Drew series.

When Nancy Drew is asked to find a missing college professor, she is drawn into a mystery involving three black keys.

I’ve always been a voracious reader. So, as a child, one of my favorite things about summer was the frequent trips to our local library, which was less than a mile from our house. Like most young girls of a certain age (ahem), my love for mysteries started

Only recently--i.e. August/September 2013--I discovered Connie Blair and her series of mysteries. After reading her first three mysteries, I grew curious as to how she might compare to my childhood fave, Nancy Drew.

Poor Nancy, perhaps it is adult hood jadedness but she seems shallow and unrealistic to me now. For example, while we frequently know Connie Blair's thoughts, including conflicting emotions such as when she longs to do one thing while another part of her feels she must do something e

The storyline was fun, but this wasn't one of my favorite Nancy Drew books. First off, I tend to prefer the books in which Bess and George are more involved with the mystery/helping Nancy. Also, all of the talk about the treasure destroying/saving mankind made the story seem a bit silly.

Nancy is very clever as she solves this mystery. She always investigates every clue to find the answer. I really liked this!

Wow. It's been so long that I can't remember the mnemonic for remembering what the black keys are, or the white keys, either.

This was a re-read of one of my favorites.
Oh boy. These guys have these keys in order to unlock a treasure chest. When they find it it's full of little silver frogs, one of which contains a powder that is either a deadly herb or a restorative herb. (What with the sculptures full of magic potions that never expire?) Nancy goes to the Florida Keys and Mexico, neither of which are close to one another and the whole Florida Key thing is a strange diversion.

Nancy loses consciousness when one of the bad guys takes down a road construction sig

I remember the first time I read Nancy Drew. It blew my mind that there were girls presented with a brain. Most of the stuff I'd read up to that time, was that girls were sugar and spice - fluffy. No brains. To also learn about George who is a tomboy was a nice validation. Carolyn Keene wrote just for me! That is how I felt. When I did more research, I was shocked to find out, Ms. Keene was actually a man ... writing under Franklin Dixon. I also loved the Hardy Boys. No wonder I loved these seri ...more

I just love Nancy Drew. It has all the cliches and imagery to create the perfect scenery for a daydream - in which I am Nancy Drew.

Impossible, really, to rate Nancy, because I read and loved her so much as a kidlet; she shaped a lot of my own writing I think. Kick-butt girls on adventures.

I really enjoyed reading about this adventure of Nancy's and I found reading about her treasure hunt to be quite thrilling especially when she came across clues that seemed impossible to figure out.

Nancy Drew, man. She's the best. I read that book about the history of Nancy Drew, and it inspired me to want to read one of the old books because it had been so long. Anyway, I pretty much enjoyed this book, and I can see why they'd be so popular with little girls. Nancy is a proactive and capable heroine who does whatever it takes to solve a mystery. She's pretty great!

This book was good, but I thought that it had a good beginning and an ok middle and an ok ending. The beginning was great and the beginning of the middle was pretty good but it got to the end to quickly. It was like Nancy Drew was searching and then all of a sudden after like one or two clues she found the answer! Overall, though it was pretty good.

My mother gave me my first Nancy Drew book when I was a kid and I have loved them ever since. Nancy was my first introduction to mysteries and I have never looked back. She is as good today as she was all those years ago. She is a whole lot braver then I would have been in this case. She keeps going even when the bad guy has really come on strong.

Nancy is hired by Terry Scott, a professor, to help figure out the mystery of the black keys. They're supposed to unlock a fantastic secret. But two of the keys have been stolen and he needs some help to solve the mystery. Nancy even gets to travel to Florida and do some digging on an island in the Keys.

I always liked these Nancy Drew books.Still remember sleeping with a flashlight under the blanket because I needed to know what happened in the end.Carolyn Keene did not disappoint with this book but this was definitely not her best work.

This was the very first Nancy Drew book I've read that I bought in a bargain store. I was in 4th grade back then and I thought becoming a detective like Nancy would be awesome. Turns out in real life becoming one aint easy. So much for childhood fantasies.
What can I say, Nancy always find a good mystery to solve and some how manages to get herself right in the thick of things. I love reading these Nancy Drew books because they are a quick read but still fun to read.
