(The comment above refers to episode 590. Same title, different cast and plot.) This story is like an offering from the Grand Guignol, filled with insanity, mayhem, and a double-cross or two. THe story begins with a mental patient trying to commit murder his wife. Her reaction is a fierce determination to see him released. As the crimes multiply, the definitions of sanity and murder only grow more confused. A nice variation on the theme of deliberately driving a meal ticket insane helps make this an above-average episode.
