Drowning by Numbers (1988)
Tired of her husband's philanderous ways, the mother of two daughters drowns her husband. With the reluctant help of the local coroner, the murder is obscured. Her daughters are having similar problems with relationships, and tend to follow their mother's example, and the coroner becomes reluctantly duplicitous. As the plot progresses, visual and spoken numbers appear in the scenes, counting from one to 100.
