Bella Tyson is a famous 40-something crime writer suffering from writer’s block ever since a bitter divorce two years before. When a fan offers her the use of an apartment in Venice, Bella jumps at it, hoping a change of scene will have her writing again. Once there, she soon meets Will, a charming Englishman, who shows her around the city. 

Enchanted by both Will and her new surroundings, Bella decides to write a supernatural murder mystery and begins researching local legends and the city’s more sinister side, including an illicit visit to the island of Poveglia, spooky former home of Venice’s asylum.
