The Mystery of Mazo de la Roche is a 2012 Canadian biographical docudrama film written and directed by Maya Gallus.
[1] The film explores the private personal life of Canadian writer Mazo de la Roche, using a mixture of archival materials, interviews and dramatic reenactments, centering in large part on the unresolved question of whether de la Roche's longtime Boston marriage with Caroline Clement was a lesbian relationship in modern terms.
[2] The dramatic reenactments star Severn Thompson as de la Roche, and Deborah Hay as Clement.
The film premiered at the 2012 Hot Docs Canadian International Documentary Festival,[3] but was distributed principally as a television broadcast on Bravo rather than theatrically.
[4] It later received a repeat screening at the 2017 festival, as part of a program of biographical documentary films about significant women in history.
