Black Widow synopsis
At a party, Broadway producer Peter Denver (Van Heflin) meets Nancy Ordway (Peggy Ann Garner), a young writer struggling to make it in New York City. Taking pity on her, Denver offers Nancy his apartment as a place to write while his wife, Iris (Gene Tierney), is away. Shortly after, Nancy is found dead in his bathroom, apparently murdered, and Denver is, of course, the main suspect. As rumors swirl about his involvement with Nancy, Denver decides to search for her killer himself.
