When two teenage gangs are arrested after clashing violently in one of Venices campi, the son of a local hero is implicated. But when Commissario Guido Brunetti is asked by a wealthy foreigner to vet this man, Monforte, for a job, he discovers that Monforte might not be such a hero after all. This seeming contradiction, and a brutal attack on one of Brunettis colleagues by a possible gang member, concentrate Brunettis attentions. Soon, he discovers the sordid hypocrisy surrounding Monfortes past, culminating in a fiery meeting of two gangs and a final opportunity for redemption. A Refiners Fire is Donna Leon at her very best: an elegant, sophisticated storyteller whose indelible characters become richer with each book, and who constantly interrogates the ambiguity between moral and legal justice.
