SOLVED. Middle Grade Mystery. Mysterious letters, group is trying figure out who was writing them.

[Ariana]

I'm currently trying to find a book for a friend and I've got a really brief description. It has to be 6th or 7th grade level. It was about these mysterious letters and a group trying to figure out who was writing them

Ariana, I copied book details to the topic header. Feel free to edit it.

Around what year was this book read? A range of years is find.

Why are the letters mysterious? What are they about? Who is receiving these letters?
Is it a group of kids (friends or siblings)?
Contemporary or historical fiction?

Absolutely Truly had a part about trying to figure out who wrote letters.

[Ariana]

Absolutely Truly was the book! Thank you so much!!!

You can also look at Chasing Vermeer--it's a middle grade mystery with two kids using pentominos (letter blocks)

[Fine]

it might be Enid Blytons "The Mystery of the Spiteful Letters"
