Meet inquisitive Evangeline. She's one-half of the precocious twelve-year-old Bresette twins. Their summer plans? The usual: Swim. Play. Squabble. Try to cope with their exasperating lawyer parents. But then a woman dies at the country club, and Evangeline notices something curious: The corpse is missing a pair of diamond earrings. Just an accidental death and petty theft? Or murder? No one but Evangeline thinks the death is suspicious, and she wants the truth. Her twin brother Raphael wants to leave it to the grown-ups, but the grown-ups haven't a clue. Armed with her wits, her curiosity, and her Barbie Doll Crime Scene Reconstruction Team, Evangeline launches her own investigation into the mystery. She discovers her search for the truth will be far more dangerous than she ever imagined.
