It's hard to believe practical, petite ex-schoolteacher Patricia Anne and amiable, ample-bodied, and outrageous Mary Alice are sisters, yet sibling rivalry has survived decades of good-natured disagreement about everything from husbands to hair color.

Now the sisters are once again combing for clues to catch a killer with a bizarre style in art -- and murder.
