Wine expert Benjamin Cooker travels to the French capital, where he is called to help care for some vineyards in Montmartre, a neighborhood full of memories for him. He stops in on an old friend. Arthur Solacroup left the Foreign Legion to open a wine shop good enough to be in the Cooker Guide. But an attempted murder brings the past back into the present. But which past? The winemaker detective and his assistant, Virgile, want to know more, and their investigation leads them from the sands of Djibouti to the vineyards of Côte du Rhône.
