Cara Massimina by Tim Parks
Bored and broke, Morris Duckworth, an English teacher in Verona, stumbles on a plan for financial salvation - to marry Massimina, a seventeen-year-old student. And if his intentions are frustrated by a suspicious, conservative family, is it any fault of his that the lovely girl chooses to elope? Obsessed by self-advancement and excitement, Morris' dreams of blackmail, theft and murder plunge him deep into a chilling nightmare of deception and violence.
