Keeper of the Flame (1944)

Steven O'Malley (Spencer Tracy) expects his reporting assignment to be a run-of-the-mill story. He is to cover the death of Robert Forrest, a hero in World War I, who died when a bridge collapsed under his car. The press conference given by Forrest's secretary (Richard Whorf), however, does not satisfy O'Malley, who decides that questioning his widow (Katharine Hepburn) could expose a richer story. The lies continue to build, until he discovers an estate building that may hold the true story.
