A sweet older couple bump into their unacquainted neighbors (Woody Allen and Diane Keaton) on the elevator one evening and invite them up to their apartment for tea and desert. When the wife is carted out the following morning after conceding to a coronary and the husband seems to offer no outward emotions regarding his recent loss, their recent guest becomes excessively suspicious and proactive, much to the annoyance of her husband. Allen's Manhattan Murder Mystery goes on longer than it should but works in his oeuvre and, as the prolific artist reveals another talent, as a detective story. The film also contains some very funny one liners.
*** out of ****
