Published in the 1920s, 'Mary Louise Solves a Mystery' is the third book in L. Frank Baum's Bluebird Books series, written under the pseudonym Edith Van Dyne. The story follows Mary Louise Burrows and her grandfather as they encounter a mysterious pair of Americans while traveling in Italy.

This book continues Baum's exploration of adolescent girl detectives, a theme he had previously introduced in earlier works.
