Meg Mackintosh Mysteries

Meg Mackintosh and The Mystery in the Locked Library by Lucinda Landon, 1993.
Meg, her brother Peter, and their grandfather are visiting their grandfather’s cousin, Alice, who was introduced in the first book of the series as the one who created the treasure hunt to find his missing Babe Ruth baseball when they were young. Grown up Alice is now a librarian, and she has created another treasure hunt for them.

One morning, she leaves them a note saying that she has a dentist appointment, but she wants them to go to the library and find something valuable that she’s hidden there before the library opens at noon. Readers follow along with the clues that Alice has left for them to solve and the pictures in the book, seeing if they can solve each part of the mystery along with Meg. In keeping with the library and book theme of the story, the clues are based around books, particularly Sherlock Holmes books.

When Meg and her family arrive at the library and begin following the clues, they discover that there are other people in the library, even though the library isn’t officially open yet. Caroline is the assistant librarian, and Gerry also works there. Then, a man named Horace Plotnik shows up, saying that he’s an antiques expert and that Alice asked him to come to appraise something.

They discover that Alice didn’t make it to her dentist appointment because someone locked her in the library’s book repair room. It turns out that the valuable item that Alice hid was a first edition of The Adventures of Sherlock Holmes by Sir Arthur Conan Doyle that recently came to the library in a donation of books, but when Meg and Peter finish the treasure hunt and go to the place where Alice did the book, it’s gone! Was it stolen by the person who locked Alice in the book repair room, and if so, who was it?
The Book is available to borrow and read for free online through Internet Archive (multiple copies).
My Reaction
I always enjoy treasure hunt stories, and like other Meg Mackintosh mysteries, this story gives readers the opportunity to figure out the clues and puzzles along with Meg. The information readers need is in the pictures of the story. When I was a kid, I particularly liked puzzles based around solving a secret code, and there is a secret code puzzle in this book that readers can solve themselves.
This treasure hunt is fun because it’s based around library and book themes, particularly focusing on Sherlock Holmes. The idea of hunting for a lost copy of a first edition Sherlock Holmes book was timely for when the book was originally written because, as the story indicates at the end, the book was written around the 100th anniversary of the character of Sherlock Holmes!
