The execution of a Vatican archivist within the shadow of the Kremlin exposes a conspiracy going back three centuries --- to the bloody era of the Russian Tsars. Before his murder, he manages to dispatch a coded message, a warning of a terrifying threat, one tied to a secret buried within the Golden Library of Tsars, a vast and treasured archive that had vanished into history.

Around 1:00 on an early spring morning, two teenage gangs are arrested after clashing violently in one of Venice’s squares. Commissario Claudia Griffoni perhaps ill-advisedly walks the last of the boys home because his father, Dario Monforte, failed to pick him up at the Questura. Coincidentally, Guido Brunetti is asked by a wealthy friend of Vice-Questore Patta to vet Monforte for a job, triggering Brunetti’s memory that 20 years earlier Monforte had been publicly celebrated as the hero of a devastating bombing of the Italian military compound in Iraq. Yet Monforte had never been awarded a medal either by the Carabinieri, his service branch, or by the Italian government. That seeming contradiction, and the brutal attack on one of Brunetti’s colleagues by a possible gang member, concentrate Brunetti’s attentions.
