The beautiful but unfaithful wife of a successful lawyer meets her untimely end at their anniversary dinner. After a suicide note is found soon after her death, it seems more likely that she was murdered, as all the dinner guests had good reason to want her dead.
Unfortunately the movie Sparkling Cyanide is not yet available on HBO Max.
