The Boxcar Children and the Chocolate Sundae Mystery, by Laura C.

I think the book The Chocolate Sundae Mystery is an awesome book and the mystery was phenomenal. There are four main characters, two girls, Jessie and Violet and two boys, Henry and Benny. They are all smart so that's how they solve the mystery. The mystery was that somebody was breaking into the parlor and stealing the ice cream. I would recommend this book to anybody who likes mysteries and ice cream stories. You will love this story.
