Scholastic and Ann M. Martin began releasing BSC Mysteries along with the regular books starting in 1991.
General[]
The books are very similar to the regular series, with the only difference being that the baby sitters are usually caught up in solving a minor mystery. In 2022, a reprint of The Mystery at Claudia's House has a release date of April 4, 2023 on Amazon[1]. The first five books have been released exclusively at Walmart.
