In the south of France, the body of a 22-year-old American tourist, Candice Strasberg, is discovered in the middle of the scrubland. Two days of rain prior to the discovery of the body made it difficult to collect evidence at the scene, as the rain had washed away the footprints. Using the victim’s diary, the police are attempting to piece together her movements. The investigation is entrusted to Gaston Delarue, the public prosecutor of Tarascon; Gérard Souffries, the investigating judge; Commissioner Bonetti of the Marseille police; and Divisional Commissioner Bretonnet of the Paris police.
