She Wrote the Book is a 1946 American comedy film directed by Charles Lamont and starring Joan Davis, Jack Oakie, and Mischa Auer.

The screenplay concerns a shy midwestern professor who travels to New York City to visit a publisher of her friend's book which turns out to be a racy bestseller.

Jane Featherstone (Joan Davis) is a buttoned-down and pedestrian professor at small town Croyden College in Great Falls, Indiana who is making plans to present a paper in New York City.

On the train to New York, Featherstone meets Eddie Caldwell, a charming engineer, and the two agree to a date once they reach the big city.

A bartender masquerading as a Count, an enamored shipping magnate, and photos that are seen back in Great Falls add twists and turns to the plot.
