Arnold
The Arnold of Arnold, like the Harry of The Trouble With Harry, is stone cold dead. But that minor detail won't stop Arnold's mistress Karen from marrying the corpse so as to come into his millions. The trick is to hide the fact that Arnold is indeed stiff as a mackerel. To accomplish this, a series of murders is a necessity. Special guest victims include Karen's wastrel brother, her dotty sister, the handyman, and even a couple of lawyers.
