Mallory and Claudia are helping Stacey unpack from her move back to Stoneybrook when they find an antique trunk in the McGill's attic. Stacey doesn't want the dusty thing, so she gives the trunk to Mallory...who finds an old diary at the bottom of it.

The diary belonged to Sophie, a girl who lived in Stacey's house in the 1890s. As Mallory reads deep into Sophie's diary, sh

(Note: this 4 stars is relative. It's not the same 4 stars I would give to, say, Faulkner's less acclaimed works. It's 4 stars in BSC-land.)

True story: I decided to reread this old Babysitters Club book because I had a nightmare that I was trapped in my childhood bedroom and Jared Mullray, aka The Ghost At Dawn's House, was rapping on the wall, waiting to come out and get me. Therefore, I decided that I needed to refresh myself on the Jared Mullray narrative (next up: The Ghost At Dawn's House a
Oh no. One of the kids that the BSC members babysit for has fallen behind his peers in reading. Buddy isn’t as fast as the other kids in his class. So Mallory is assigned the task of tutoring him. While all this is going on Mallory also finds a mysterious diary in a trunk that was in Stacey’s attic in her new house. This isn’t any ordinary diary though, it was written over 100 years ago by a 12 year old girl named Sophie! As she is reading through it she discovers that Sophie’s father was wrongl ...more

wow, this was way better than I expected based on the synopsis. okay. stacey, mallory, and claudia find a bunch of cool old stuff in the attic of the 19th-century house stacey just moved into. one cool thing is a trunk, that mallory takes home and eventually opens to find victorian clothes and a victorian girl's diary. the diary details a mystery involving the girl's maternal grandfather accusing the girl's father of thievery. meanwhile, buddy barrett is h

Mallory finda diary full of hard to read handwriting and, as a result, I don't read half this book.

Mallory and Stacey find an old diary in a trunk in the attic of Stacey’s new house. The diary belonged to Sophie, a 12-year-old from 1894, who tells the ups and downs of her life, ending with a crime: Sophie’s father, a scoundrel, was blamed for the disappearance of a painting from her grandfather’s house. Mallory is meanwhile tutoring Buddy Barrett with his reading. When she discovers he’s not mot

So Stacey moved back to Stoneybrook and there's crap in the attic. Including a mysterious trunk, which she gives away to Mallory and which makes so much sense. (Seriously, do relics from the 1890s usually sit around in attics without getting noticed when houses are sold? I didn't think that actually happened unless the house was handed down within a family or something.) There's a convenient little diary in the trunk (along with old clothes), and Mallory's totally into it. Because a girl her age ...more
In my quest to read all the BSC books in order, I found myself with another BSC ghost book without actual ghosts this week. I always love the Mallory books because she's bookish and always promotes reading. I loved that she used comic books to help Buddy, a very reluctant reader, enjoy reading. I know Mallory wants to be a writer but maybe her day job will be a Teen Services Librarian who promotes graphic novels and comics???

This book is totally for mystery lovers. I loved this book. I wish I had been given that trunk. I would keep all the dresses. Lucky I don’t have a sister! I want you to READ THIS BOOK!

Thanks for reading this! I would be happier if you read the book, though.

This is one of my favorites simply for the mystery involved. I'm a sucker for the Victorian/Edwardian era, and I always liked Mallory despite fandom and possibly canon's hatred for her. This one was a fun read!
Okay, so I always did like this one. Then again, I always liked Mallory. She was a nerdy type girl who loved to read and wanted to be an author, just like me. What wasn't to like!? This one was actually fun, and I can now (as an adult) tie this to a real life story. I actually met another writer who was in residence at a major university during a weekend workshop. She was basing her entire thesis around a diary she had found at a yard sale, and the girl who had written it. Seriously reminded me ...more

The best part of this wasn't the mystery (though I love the pre-Mystery mysteries, they're more realistic,) even if I quite enjoyed Madame Kristin's séance. The best part of this book, surprisingly, was the "baby-sitting" (aka tutoring) that Mallory did throughout the book. I love that Mallory got Buddy excited about reading, and I loved the ways that she did it. (Although the more I think of it, the more I enjoy learning about Stoneybrooke's history and Old Hickory. I need to know if his son-in ...more

Read like a Nancy Drew notebook! Always enjoy how curious Mallory is.

I loved the BSC growing up, and have decided to re-read (or read for the first time) some of the books in the series. Which of the members are you? :)

Mallory is distracted from her whining and crying by a diary she discovers in an old trunk. She and Buddy Barrett (oh yeah, and the BSC) set out to solve the so-called mystery. Is Stacey's house haunted? What happened to some old painting? Who really cares?

Things I remember from reading this as a kid:
I loved this book as a kid, partly because Mallory helps Buddy learn to love reading, and partly because I desperately wanted to discover an old diary in an old trunk. I remember being really intrig

I'm really beginning to like Mallory! In Mallory and the Mystery Diary she finds a diary from the late 1800s in Stacey's attic. Mallory makes a reader of Buddy Barrett and together they solve the mystery of the diary. Loved this book! I also really liked how Mallory worked with Buddy to make him a reader. I know that feeling and it is a great one! Love this sweet nostalgic series!

The majority of the girls REALLY annoyed me in this one. It
I am aware I am way too old to start reading the pending non-read BSC books, but I've been a huge fan of the series when I was younger, and the library at my school only had 1-28. Once I reached Nr. 28 I made a promise to read all of the rest once I were older and had money to purchase them.

So here I am, years and years after, reading Mallory's adventures. She has always been one of my least favorites (only 11-years-old and a baby-sitter?). But this volume was fun to read, to re-visit all the ch

Stacey moves back to Stoneybrook and gives Mallory a mysterious trunk that was in the attic. Mallory's thrilled at the discovery of a diary by a teen girl in the old trunk, and she's devouring the life story of a girl similar to her (but from the 1890s) when she realizes there's a mystery she might be able to solve--something this girl was caught up in. Can she and her babysitting charge solve the mystery?

+1 for such a cool feeling--discovery of a diary by a teenage girl from the 19th century wo

The BSC is solving a mystery, long before the Baby-sitter's Mysteries was published! This one takes place after Stacy's mom had "got it goin on" by taking her back to Stoneybrook after mom and dad divorce, and Mallory has narrating duties. Mal has uncovered a chest (which is a bitch to open) and finds a diary from a girl pioneer from 1894 (which is a bitch to read) and unlocks a 100-year-old mystery (which is a bigger bitch to solve). The BSC is on the case (and you do NOT mess with these bitche ...more

Stacey has moved into her new home, behind Mallory's, and as a welcome home Mal takes over a tuna casserole (side note: I've never had tuna casserole, but it sounds disgusting!). While she's there, she helps Stacey take some boxes up to the attic and they discover all this old junk up there that has been left behind by different families over the years. Mallory finds this awesome old trunk the rest here.

For some reason this is the one BSC books that I read this time last year and never reviewed. I'm not sure what happened as I reviewed all the others. I remember finding this a fairly enjoyable, fun BSC book but in honestly, I can barely remember the plot. It did seem weird that Mallory was the one to solve the mystery in Stacey's house, but it was nice to see these two girls being close friends as it's one of the underexplored friendships in the series despite the fact that the two girls live s ...more

I love this book, it was always one of my favorites. Mallory and Stacey find an old trunk in Stacey's attic. Since Stacey and her mom don't want it, Mallory takes it home. She and Vanessa find it's filled with dresses and a diary. Soon the BSC is swept away in a mystery of a stolen portrait. The ending was simple. I would've liked to hear one or two BSC members form a theory about the conclusion. Parents should know there is an attempted seance, but most of the girls take it as a game. All in al ...more
Fantastic books for young girls getting into reading!! Great stories about friendship and life lessons. The characters deal with all sorts of situations and often find responsible solutions to problems.

I loved this series growing up and wanted to start my own babysitting business with friends. Great lessons in entrepreneurship for tweens.

The books may be dated with out references to modern technology but the story stands and lessons are still relevant.

Awesome books that girls will love! And the

Read ages ago. Re-reading in 2015.

These books make me miss the simple days of my 1980's childhood. For example, before cell phones were a thing, we actually had a list of phone numbers on the fridge to consult when babysitting, just like they did in this book. We actually played with board games and ran around outside. So much has changed since then. Makes me wonder how different this series might've been if written today.

Despite it being a Mallory book, Mallory and the Mystery Diary is one of the best Baby Sitters Club books I have ever read. Mal is at her best here. I enjoyed the scenes of her tutoring Buddy Barrett and trying to figure out the mystery of Sophie's diary, a girl who used to live in Stacey's new house More than 100 years earlier.

So I'm listening to this great podcast, The Baby-Sitters Club Club, and decided to read a book before listening to the episode for once. Also, I am going to reach my 50-books-in-a-year goal, I fucking AM, I don't care HOW.
