Local businessman Buford Fontleroy Deale III is found shot dead in front of Harriet's Books in downtown Sinful. A blood-soaked pajama top is tied around his chest. And he's wearing only one shoe.

The sheriff wants to talk to Harriet. Sinful's beloved bookseller was one of the last people to see Deale alive. Fortune, Ida Belle, Gertie, and Mary-Alice need to get to Harriet before the sheriff does. They want to clear Harriet's name, and stop whoever was behind the bizarre murder.

Except no one can find Harriet...
