Alice Winter, one of Britain’s most dazzling socialites, seemingly has the perfect life --- a lavish home in posh Knightsbridge, a grand estate in Devon, millions of followers on social media who eagerly await her next post. But when she disappears without a trace while on holiday with three old friends from Cambridge, her desperate husband, the real estate baron Edward Knight, turns to none other than Gabriel Allon to find her. Gabriel soon discovers that Alice Winter is not the woman she appears to be. She has a reckless side, and she has secrets. But Edward Knight has a secret too, a secret so dangerous that Gabriel will have no choice but to return to the life he thought he had left behind. An old enemy lurks there, waiting for him to make one misstep, waiting for the perfect moment to exact vengeance.

Gabriel Allon has been awarded a commission to restore one of the most important paintings in Venice. But when he discovers the body of a mysterious woman floating in the waters of the Venetian Lagoon, he finds himself in a desperate race to recover a lost masterpiece by Leonardo da Vinci. The painting, a portrait of a beautiful young girl, has been gathering dust in a storeroom at the Vatican Museums for more than a century, misattributed and hidden beneath a worthless picture by an unknown artist. Because no one knows that the Leonardo is there, no one notices when it disappears one night during a suspicious power outage. No one but the ruthless mobsters and moneymen behind the theft --- and the mysterious woman Gabriel found in a watery grave in Venice. A woman without a name. A woman without a face.

Art restorer and legendary spy Gabriel Allon has slipped quietly into London to attend a reception at the Courtauld Gallery celebrating the return of a stolen self-portrait by Vincent van Gogh. But when an old friend from the Devon and Cornwall Police seeks his help with a baffling murder investigation, he finds himself pursuing a powerful and dangerous new adversary. The victim is Charlotte Blake, a celebrated professor of art history from Oxford who spends her weekends in the same seaside village where Gabriel once lived under an assumed identity. Her murder appears to be the work of a diabolical serial killer who has been terrorizing the Cornish countryside. But there are a number of telltale inconsistencies, including a missing mobile phone. And then there is the mysterious three-letter cypher she left behind on a notepad in her study.

Legendary art restorer and spy Gabriel Allon joins forces with a brilliant and beautiful master-thief to track down the world’s most valuable missing painting. But soon he finds himself in a desperate race to prevent an unthinkable conflict between Russia and the West.

Legendary spy and art restorer Gabriel Allon has at long last severed ties with Israeli intelligence and settled quietly in Venice. His beautiful wife, Chiara, has taken over the day-to-day management of the Tiepolo Restoration Company, and their two young children are discreetly enrolled in a neighborhood scuola elementare. For his part, Gabriel spends his days wandering the streets and canals of the watery city, bidding farewell to the demons of his tragic, violent past. But when the eccentric London art dealer Julian Isherwood asks Gabriel to investigate the circumstances surrounding the rediscovery and lucrative sale of a centuries-old painting, he is drawn into a deadly game of cat and mouse where nothing is as it seems.

Once Russia’s richest man, Viktor Orlov now resides in splendid exile in London, where he has waged a tireless crusade against the authoritarian kleptocrats who have seized control of the Kremlin. Yet somehow, in the midst of a global pandemic, Russia’s vengeful president finally manages to cross Orlov’s name off his kill list. Gabriel Allon owes his very life to Viktor Orlov, and his desperate search for the truth eventually will take him to Geneva, where a private intelligence service controlled by a childhood friend of the Russian president is using KGB-style “active measures” to undermine the West from within. Known as the Haydn Group, the unit is plotting an unspeakable act of violence that will plunge an already divided America into chaos and leave Russia unchallenged.

When Pope Paul VII dies suddenly, Gabriel Allon is summoned to Rome by the Holy Father’s loyal private secretary, Archbishop Luigi Donati. A billion Catholic faithful have been told that the pope died of a heart attack. Donati, however, has two good reasons to suspect his master was murdered. The Swiss Guard who was standing watch outside the papal apartments the night of the pope’s death is missing. So, too, is the letter the Holy Father was writing during the final hours of his life. A letter that was addressed to Gabriel. While researching in the Vatican Secret Archives, I came upon a most remarkable book… The book is a long-suppressed gospel that calls into question the accuracy of the New Testament’s depiction of one of the most portentous events in human history.

Gabriel Allon, the legendary chief of Israeli intelligence, has spent most of his life fighting terrorists, including the murderous jihadists financed by Saudi Arabia. Prince Khalid --- or KBM, as he is known --- has pledged to finally break the bond between the Kingdom and radical Islam. For that reason alone, Gabriel regards him as a valuable if flawed partner. Together they will become unlikely allies in a deadly secret war for control of the Middle East. The life of a child, and the throne of Saudi Arabia, hang in the balance. Both men have made their share of enemies. And both have everything to lose.

At an exclusive private school in Switzerland, mystery surrounds the identity of the beautiful girl who arrives each morning and leaves each afternoon in a heavily protected motorcade fit for a head of state. She is said to be the daughter of a wealthy international businessman. She is not. And when she is brutally kidnapped across the border in the Haute-Savoie region of France, Gabriel Allon, the legendary chief of Israeli intelligence, is thrust into a deadly secret war with an old enemy that will determine the future of the Middle East --- and perhaps the world.

In an isolated village in the mountains of Andalusia, a mysterious Frenchwoman begins work on a dangerous memoir. It is the story of a man she once loved in the Beirut of old, and a child taken from her in treason’s name. The woman is the keeper of the Kremlin’s most closely guarded secret. Long ago, the KGB inserted a mole into the heart of the West --- a mole who stands on the doorstep of ultimate power. Only one man can unravel the conspiracy: Gabriel Allon, the legendary art restorer and assassin who serves as the chief of Israel’s vaunted secret intelligence service. Gabriel and the Russians will engage in a final epic showdown, with the fate of the postwar global order hanging in the balance.

Four months after the deadliest attack on the American homeland since 9/11, terrorists leave a trail of carnage through London’s West End. The attack is a brilliant feat of planning and secrecy, but with one loose thread. The thread leads Gabriel Allon and his team of operatives to the south of France and to the gilded doorstep of Jean-Luc Martel and Olivia Watson. A beautiful former British fashion model, Olivia pretends not to know that the true source of Martel’s enormous wealth is drugs. And Martel turns a blind eye to the fact that he is doing business with a man whose objective is the very destruction of the West. Together, under Gabriel’s skilled hand, they will become an unlikely pair of heroes in the global war on terror.
