A Park Avenue society beauty is murdered in her apartment bringing Detective Mark McPherson to New York's most elegant neighborhood. As he tries to get inside the head of the victim, Laura Hunt, he also questions the men in her life; the acerbic critic Waldo Lydecker and playboy fiance Shelby Carpenter. Lulled by her stunning portrait, fine liquor and classical music, McPherson doesn't know he's in for a heart-stopping shock with the sudden appearance of a woman who seems to be Laura herself.
