On March 24, 1946, World Chess Champion, Alexander Alekhine, is found dead in his hotel room in Estoril, Portugal. The cause of death remains mired in controversy when, three-quarters of a century later, a letter of his that could rock the art world is unearthed in a routine home renovation in upstate New York. The letter is addressed to a person of international repute and offers information about art works looted during the German occupation of Paris. When the young man in possession of the letter is brutally murdered, his mentor, art history professor Harrison Wheatley and Harrison's sleuthing partner, art magazine editor Erika Shawn, hurl themselves into the dual mission of tracking down both the killer and the looted art. The hunt takes the couple to far-flung locations, and as the stakes rise along with the murder count, it looks like the denouement will take place far from the comforts of home.
