Who Stole the Wizard of Oz? was published by Alfred A. Knopf in 1981. Becky discovers that a library copy of The Wonderful Wizard of Oz has been stolen and replaced with a copy containing hidden messages. The mystery that unfolds involves a treasure hunt through the library’s collection, with clues embedded in books themselves — a conceit that celebrated the library as a place of adventure and the book as an object capable of holding secrets beyond its text.
The novel was aimed at younger readers and reflected Avi’s conviction that mysteries should be accessible to children without being condescending. The library setting was central: the building itself was the adventure landscape, and the books were both clues and characters.
