Book excerpt: Murder on a Bad Hair Day 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. No sooner do the Southern sisters discover a common interest in some local art, when they're arguing the artistic merits of some well-coiffured heads at a gallery opening. A few hours later, one of those pretty ladies ends up dead -- with not a hair out of place. The other shows up on Patricia Anne's doorstep dazed, disheveled, and telling a wild tale of a narrow escape from some deadly cuts. Now the sisters are once again combing for clues to catch a killer with a bizarre style in art -- and murder.
