Prissy Baxter inherited a lot of money when her husband died.

She keeps her sister, Liz, on a tight allowance -- but Prissy's will says if Liz is married to Prissy's approval when Prissy dies, then Liz will inherit.

However, if Liz is single or married to someone Prissy doesn't approve of, then all the money goes to charity... Is it a recipe for murder -- or worse?
