Roth

The Louvre's Curator is charged with keeping the Mona Lisa safe. Vernay has a summer policy for the painting that forges an opening for a thief who exploits Vernay's desperation to escape from the daily horror of his home. Roth tries to unravel the mystery of how the Mona Lisa was stolen from the Louvre, and whether its missing Curator was involved. He learns something in his past is the key.

When Roth is sent to speak at a ceremony held in a Paris theatre, people die but it's only the beginning. Paris is rocked by more terror as Russia invades Ukraine and suspicions grow that Moscow is to blame for the attacks. Spooks, Russian oligarchs and émigrés trying to remain free in the West form a complex web Roth has to unravel when he finds a shipment of looted paintings lost since WWII.

When Roth, an Interpol expert becomes involved in the counterfeiting of English banknotes he knows the forger he's chasing may as well be a ghost. The case spreads its tendrils to Paris where Roth works and enjoys a life of privilege among the rich and powerful but when a specimen of the rare two cent Hawaiian Missionary stamp goes up for auction the bodies accumulate and Roth himself is a target.
