Kiss Before Dying, A (1956) - You've Concealed It Wonderfully

Gobbling up more Tucson scenery, Virginia Leith as Ellen, wealthy sister of Dorothy (Joanne Woodward), whose murder has been officially ruled a suicide, receives a memento, then a phone call (from Bud, Robert Wagner, who committed the murder, and who is apparently now dating her!), then clashes with her cruel father (George MacReady), in A Kiss Before Dying, 1956.
