Her left eye is swollen shut and her lip is badly puffed. She's covered with dirt, mud, filth and when Dora offers her a candy bar the woman actually eats crumbs fallen in the muck with her mouth.

He is told that unless his firm, Melodie's, doesn't find that her husband killed her, that the police will shut down their company. What do all three of these cases have in common? Sibling Rivalr pits Dora against Melodie. Read Sibling Rivalry to find out why.
