Used book – Le signe de Saturne, Jean-Yves Loude

Three disappearances take place in the heart of Lyon: Mob, the poet of the creative market; Venus Nin, the prima ballerina of the Malcom Haley troupe, and Antoine Péry, the historian... When the fourth disappearance occurs, Commissioner Bigot is put on the case and immediately declares, "It's obvious that the art world is being targeted!" Disappearances five, six, and seven are simultaneous. The city of Lyon is in a state of shock. The only clue is a silver replica of the sign of Saturn, crossed by a furious lightning bolt!
