There&;s only one Auntie Poldi: bewigged, cursing in Bavarian, and knocking back a wee shot of grappa as a pre-breakfast aperitif . . . or is there? No one is as they seem (and sound) in this hilarious new mystery featuring Sicily&;s sultriest sleuth. Strange dealings are afoot in the Apostolic Palace&;a nun leapt to her death shortly after participating in a seemingly routine exorcism. But when a priest clad in Gammarelli and a Vatican commissario with an almost unholy level of sex appeal turn up at her door, Poldi is shocked to hear that she&;s a suspect in their case.   Who is the woman being exorcised, and where has she disappeared to? And why in the world does she claim, in perfect Bavarian, to be Poldi, Isolde Oberreiter, of Torre Archirafi?    Poldi will need all the help she can get to clear her name, but her nephew has been distracted by a love affair gone sour, someone in the town has been spraying graffiti death threats on her front door, and her local friends seem to be avoiding her. And even Vito Montana balks when Poldi discovers that the case hinges on a lost Madonna statue, stolen years ago from the pope himself.   Forza, Poldi! With a pair of mysterious twins dogging her every move and a mandate to maintain sobriety, will Poldi be able to find the lost statue in time, and survive her sixty-first birthday?
