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. Gabriel soon discovers that Professor Blake was searching for a looted Picasso worth more than a $100 million, and he takes up the chase for the painting as only he can--with six Impressionist canvases forged by his own hand and an unlikely team of operatives that includes a world-famous violinist, a beautiful master thief, and a lethal contract killer turned British spy.

"After talking her way into a job with Dan Mansfield, the leading investigative reporter in Chicago, rising young journalist Jules Roth is given an unusual--and very secret--assignment. Dan needs her to locate a painting stolen by the Nazis more than 75 years earlier: legendary Expressionist artist Ernst Engel's most famous work, Woman on Fire. World-renowned shoe designer Ellis Baum wants this portrait of a beautiful, mysterious woman for deeply personal reasons, and has enlisted Dan's help to find it. But Jules doesn't have much time; the famous designer is dying. Meanwhile, in Europe, provocative and powerful Margaux de Laurent also searches for the painting. Heir to her art collector family's millions, Margaux is a cunning gallerist who gets everything she wants. The only thing standing in her way is Jules. Yet the passionate and determined Jules has unexpected resources of her own, including Adam Baum, Ellis's grandson. A recovering addict and brilliant artist in his own right, Adam was once in Margaux's clutches. He knows how ruthless she is, and he'll do anything to help Jules locate the painting before Margaux gets to it first"--

Art investigator Madison Dupre knew the offer was too good to be true: $20,000 for a quick trip to Dubai, the fantastic Arabian Nights city on the Persian Gulf. The call came from Sir Henri Lipton, a man who was supposed to be dead—and who she sincerely had hoped was burning in hell because he had ruined her career before his violent “demise.” He told her only one tantalizing thing about the piece of art: “Let’s just say it’s a couple thousand years old and was buried with Christ.” The fact the offer came from a man wanted on three continents for art looting was fair warning that there would be a catch. But with credit collectors and an avaricious landlord pounding at her door, Madison listened when the devil whispered magic words in her ear: $20,000– cash – upfront. There was a catch, of course. A number of them. Sir Henri was up to his neck in conspiracies and needed someone to deflect the danger onto—not to mention frame for the most audacious art theft in history. Dubai, a city that has been called Las Vegas on steroids, would just be the first stop for Madison on a quest that takes her to an ancient Mesopotamian city, the dark streets of exotic Istanbul, Venice at Carnival time, and a cathedral where the most sacred object of Christendom is stored. Along the way, she finds romance in the arms of a Russian agent who she doesn’t trust—and can’t resist.
