The Family Secret (1951)

After accidentally killing his best friend, Art Bradley, in self-defense outside of a tavern, law student David Clark flees the scene of the crime. Eventually he returns home, where he finds his parents entertaining his father Howard's law partner, Donald Muir, and Art's mother Sybil, their neighbor. Realizing it would look unusual if he avoided their company, David joins his parents and plays cards with Sybil. Later, Howard receives a telephone call regarding Art's murder and privately tells his wife Ellen. Later after informing Sybil, Howard describes Art's death, as David listens uneasily before retiring to his room in a turmoil of indecision.
