A Skeleton in the Closet

Twelve-year-old Mizzy wants to prove to the world that she can solve mysteries just like Sherlock Holmes, despite a reputation for tall tales. A charming new mystery series for middle-grade readers, starring a girl with Down syndrome.

Twelve-year-old Mizzy dreams of being a detective and she won't let anything stand in her way — not her reputation for tall tales, or her embarrassing fear of escalators, and definitely not her Down syndrome. Dumped for the summer with cousins who've outgrown her, Mizzy feels even more sidelined than usual. But when she discovers Great Aunt Jane's diaries in a locked wardrobe in their spare room, and realizes her aunt didn't just die in her sleep but under suspicious circumstances, everything changes. What's more . . . someone in the family appears to have been involved.

Under the guise of a family tree project for school, and armed with a brand-new set of Pip-Squeaks markers, Mizzy grabs the chance to prove herself to her cousins — and the world.A New York Public Library Best Book for Kids of 2025
