When a young woman returns from holiday to find her elderly neighbour dead, she immediately alerts the police. Commissario Brunetti is called to the scene but, though there are signs of a struggle, it seems the woman has simply suffered a fatal heart attack. Vice-Questore Patta is eager to dismiss the case as a death from natural causes, but Brunetti believes there is more to it than that. His suspicions are further aroused when the medical examiner finds faint bruising around the victim's neck and shoulders, indicating that someone might have grabbed and shaken her. Could this have caused her heart attack? Was someone threatening her?
Conversations with the woman's son, her upstairs neighbour, and the nun in charge of the old-age home where she volunteered, do little to satisfy Brunetti's nagging curiosity. With the help of Inspector Vianello and the ever-resourceful Signorina Elettra, Brunetti is determined to get to the truth and find some measure of justice.
Insightful and emotionally powerful, Drawing Conclusions reaffirms Donna Leon's status as one of the masters of literary crime fiction.
