The Flanders Panel
Arturo Pérez-Reverte
 Julia, an art restorer and evaluator living in Madrid, discovers a painted-over message on a 1471 Flemish masterpiece — appearing as the cover of the book —called La partida de ajedrez (The Chess Game) reading "Qvis Necavit Eqvitem", written in Latin (English: "Who killed the knight?"). With the help of her old friend and father-figure, the flamboyantly homosexual César, and Muñoz, a quiet local chess master, Julia works to uncover the mystery of a 500-year-old murder. At the same time, however, Julia faces danger of her own, as several people helping her along her search are also murdered.
