Falling In Love by Donna Leon
As an opera superstar at La Fenice in Venice, Flavia Petrelli is well acquainted with attention from adoring fans and aspiring singers.
But when one anonymous admirer inundates her with bouquets of yellow roses, which start to appear in her dressing room and even inside her locked apartment, she begins to fear for her safety and calls in an old friend. Enter Commissario Brunetti.
But soon, the threat becomes more serious. Brunetti must enter the psyche of an obsessive fan and find the culprit before anyone, especially Flavia, comes to any harm.
