Master of international intrigue Daniel Silva, the #1 New York Times bestselling author, comes an explosive new thriller featuring art restorer and legendary spy Gabriel Allon. The most beautiful music hides the deadliest secrets ... Viktor Orlov had a longstanding appointment with death. Once Russia's richest man, he now resides in exile in London, where he is waging a crusade against the kleptocrats who have seized control of the Kremlin. His mansion is protected by armed bodyguards. Yet somehow, on a rainy summer evening, in the midst of a global pandemic, Russia's vengeful president finally manages to cross Orlov's name off his kill list. Before him was the receiver from his landline telephone, a half-drunk glass of red wine, and a stack of documents ... The documents are contaminated with a deadly nerve agent. The Metropolitan Police determine that they were delivered by one of Orlov's employees, a prominent investigative reporter. And when the reporter vanishes hours after the killing, MI6 concludes she is a Moscow Center assassin who penetrated the billionaire's formidable defenses. But Gabriel Allon believes his friends in British intelligence are dangerously mistaken. His search for the truth will take him to Geneva, where a private intelligence service is plotting an act of violence that will plunge an already divided America into chaos. Only Allon, with the help of a brilliant young woman employed by the world's dirtiest bank, can stop it....
