The memorable characters and Venetian drama that have long captivated Donna Leon's many readers are on full display in The Temptation of Forgiveness. Surprised, if not dismayed, to discover from his superior, Vice-Questore Patta, that leaks are emanating from the Questura, Commissario Guido Brunetti is even more surprised by the appearance in his office of a friend of his wife's, fearful that her son is using drugs. When Tullio Gasparini, the woman's husband, is found unconscious and with a serious head injury at the foot of a bridge in Venice after midnight, Brunetti is drawn to pursue a possible connection to the boy's behaviour. But the truth is not straightforward.

As the novel unfolds in Donna Leon's exquisite chronicle of Venetian life in all its blissful and sordid aspects, Brunetti pursues several false and contradictory leads while growing ever more impressed by the intuition of his fellow Commissario, Claudia Griffoni, and by the endless resourcefulness and craftiness of Signorina Elettra, Patta's secretary and gate-keeper. Exasperated by the petty bureaucracy that constantly bedevils him and threatens to expose Signorina Elettra, Brunetti is steadied by the embrace of his own family and by his passion for the classics. This predilection leads him to read Sophocles' Antigone, and, in its light, consider the terrible consequences to which the actions of a tender heart can lead.
