An exciting story of intrigue and murder in Venice, July, 1613: A suspicious drowning in the Lagoon and a deadly assault on a bridge shatter the dreams of Captain Lorenzo Contarini and his fiancée, la Signorina Caterina Zanchi, members of two noble Venetian families. While Caterina’s severe injuries banish her from society, her parents remove their other daughter, Leonora, from the convent to become Lorenzo’s hasty wife. Lorenzo’s investigation into his half-sister’s death compels him to accuse his maternal aunt, the Abbess of San Zaccaria, of murder.
