Query: Enjoyable, Lighthearted Mystery

Woody Allen plays a book editor (Larry Lipton) married to Carol (Diane Keaton) who is much more of a free spirit than Larry. Carol is eager to investigate the possible murder of a neighbor, Larry isn't, and she starts to drift away towards divorced friend Ted (Alan Alda) who is more interested. Meanwhile, a female writer (Anjelica Huston) is attracted to Larry. Turns out the 'victim' wasn't killed until after the supposed murder (her sister, it turns out, who dies of a heart attack). Lots of loose ends, danger, and silliness. The crime is solve, Larry and Carol's relationship is strengthened, and Ted ends up with Angelica.
