She is not as finicky as Poirot and nor is she as condescending as Sherlock. But just like her fellow detectives, she has a fine brain under her well-coiffed locks and will always hold a special place in my long-buried girlish heart. When I came across an ancient, dog-eared, much-doodled Nancy Drew mystery at my library, I couldn’t resist picking it up.

In The Mystery of the 99 Steps , Nancy Drew is working on a dual case with her father, eminent lawyer Carson Drew. A lady called Mrs. Josette B

When I was about 10 or 11, my mother signed me up for a book of the month club. Every month, I received two Nancy Drew or two Hardy Boys books. Every month, they were both read in a week and I was asking when the next book would be there!
I thank my mother for recognizing and encouraging my love of reading.

The Mystery of the 99 Steps is about Nancy Drew, Carson Drew (her father), and George (or Georgia) and Bess (best friends).

Nancy hears about a dream from a woman who lives in River Heights and goes to France with her best friends. While Nancy is searching for 99 steps from her friends dream she notices that one of the people she sees at a party is actually a man in disguise.

Nancy tries to figure out who the man is but can't figure out more than the fact that he has a twin brother in River Heig

The story involves the ancient practice of alchemy, and the equally ancient practice of cheating people out of their money. In this case Nancy, George and Bess go to France to work with Mr. Drew who is trying to convince a financier to stop selling all his assets.

A woman Nancy knows has nightmares of falling down a long flight of stairs. As happens every so often, someone tries to stop Nancy from going to France by sending her a message. Even once in France someone tries to stop her and seems q

I enjoyed the fact that Nancy got to go to France with her friends Bess and George and take on some seriously sinister characters, but I'm not sure I really bought the ending of the book. Without giving away spoilers let's just say that from the start you could tell that a financier was being hoodwinked in some way. When that way came to light, I just didn't feel like it was plausible. I mean, if a guy is smart enough to make it take far in business, I don't think he would fall for something tha ...more

3.5 stars

This isn't my personal favorite of the Nancy Drew series, but it's a perfectly competent addition to the series, and still holds up as a light page-turner of a mystery. The characters are still in good form, and though the mystery plotline isn't always wholly believable, I still enjoyed the experience.
The Mystery of the 99 Steps is an engaging and intelligent mystery story with some nice creativity to its storyline, and though there is still a certain degree of predictability(serious

I honestly love these books I just wished they were more detailed. I don't like how the author over reacts and adds !!!!! every time somthing "dramatic" happens. The plots ok but it ain't no match for teen fiction. I wish I knew more on Nancy's personal life and I wish there was a little more questioning suspects and a little less constantly reporting to the police. I don't really like that part it gets annoying. I like the characters (I don't LOVE them but what can you do?) but over all I wish ...more

Because of a Goodreads friend adding these books, it reminded me that I'd forgotten about them. How could I!! It's because of Nancy Drew, The Hardy Boys, and Andre Norton's Witch World series that I fell in love with fiction. (And Jack London's White Fang, and the Book Black Beauty, which made me cry).

These are dated tales, but they did the job for their time. Having a female lead was rather progressive for the day, even if many situations would cause a mutiny now... lol. What can I say, as a 12

The Mystery of the 99 Steps is a children's story by Carolyn Keene (pseudonym) and the 43rd book in the Nancy Drew series.

Despite warnings from a stranger, eighteen-year-old Nancy Drew and her friends set out for France to search for a flight of 99 steps that may help solve the mystery of a friend's strange dream and a possible case of blackmail.

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

I loved the Nancy Drew books as a kid. I voraciously read every one I could get my hands on. Reading this now, I'm struck by several things (some of which other reviewers have also pointed out):

1. The stereotypical characters
Every character is a 'type' to a tee. We've got the perfect one, the uber supportive parent, the impulsive tomboy, the part-of-the-family hired help, the fat friend, etc. When you're a kid you may not notice it, but as an adult you keep looking for flaws beyond the obvious a

Minor spoilers ahead.

In reading old children's mystery/action/suspense books, I'm finding myself running into many similar "types". There's the supportive parent (usually the father), the comic relief, working class family member (a housekeeper, a cook, etc), etc etc etc. Out of the three big titles I've been reading (Hardy Boys, Nancy Drew, and Tom Swift Jr), Nancy Drew has these types down to a science, and this book really highlights the weaknesses of writing with them.

I didn't enjoy this one as much as the other books I have read and the main reason for it would be tag-along helpers known as George and Bess. I mean I am all for her getting help from time to time, but the extra girls just ruined it for me, I mean they really served no purpose and slowed Nancy down.
This book starts with a dream from some lady, who is having nightmares about 99 steps, so Nancy believes finding these steps will help the lady stop having the dream. Only thing is, Nancy will have
Nancy et ses amies vont a la France! And bien sur, they all speak French, because who doesn't? They go because some neighbor of Nancy's has a DREAM about 99 steps and so of course she freaks out and has Nancy go and investigate. I have recurrent dreams about the inability to open combination locks. Please help me, Nancy.

Anyway, Carson is helping a totally different client with an actual case in Paris at the same time, but apparently it has to do with this woman's dream. Creepy. And there are twi

Nancy Drew and the Hardy Boys is where my love of reading began. My mom bought me one of these books every couple of weeks and I loved them. I found this book at a book clearance for a library and I just had to buy it. It still was just as much fun to read now as it was when I was kid. My only regret is that I did not keep the books, I gave them away to my cousins when I was older.

This book was disappointing, considering it is one of the most popular books in the series. No action at all. I'll just stick with Trixie Belden from now on. Kind of sad I can find so many faulty things with Nancy Drew books now, I used to love them when I was little.

This was the first Nancy Drew book I read when I was younger. I remember looking in the school library for a book to read and picking this one. It was so good and got me hooked on Nancy Drew, mystery books and wanting to be a secret detective, haha.

The mystery of the 99 steps is a very intreging book. Carolyn Keene is a fabulos writer she can really get you hooked in to her wounderous novel series Nancy Drew I have read many of her eye popping storys.She can write those special books you just can't put down.
The book is about the keen young adult Nancy Drew in a misson to solve the storys riddles she has to help a poor gentelman who was tricked in to giving money to a mad man. Will Nancy ever help the man? In this case with so little info

I read this book with 7th grade student, and she loved it! Nancy Drew and her friends, Bess and George, find themselves on another mystery case, this time taking them to France. Nancy and her father both have mysteries to solve, but could their cases be connected? Nancy soon realizes that she is being watched; how long can she escape danger?

The text of this book provides great opportunity to learn new vocabulary--even a little French. This particular Nancy Drew mystery might be considered more c

The origin of this mystery was a little weird -to put it mildly but eventually I would say it got more interesting. I loved that it was set in France, and remember that it was a bit of a surprise as I wasn't expecting that, and since I'm lover of all (if not most) things French that didn't hurt one bit.

The story was quite delightful but a bit hard to keep up with, it kind of felt like a wild goose chase sometimes with Nancy flitting from one place to another and there were parts I had to re-read

On the other hand, before she leaves, a strange person named Monsieur Neuf tells the girl not to do the mission.
