Dark Secrets in the Camargue - Captain Roger Blanc's second case. August, the air over Provence shimmers in oppressive heat. Captain Roger Blanc and his colleague Marius Tonon are called to the Camargue: a black fighting bull has broken loose and gored a cyclist. At first, it seems like a bizarre accident. Until Blanc discovers a clue indicating that someone intentionally opened the gate. The deceased is Albert Cohen, a reporter for a political magazine, a fashion intellectual from Paris, and a television celebrity. He was in the Camargue to write a major article about Vincent van Gogh. But what could that have to do with the attack? While a cheerful construction crew removes the old roof from his half-ruined oil mill but does not cover it with a new one, Blanc uncovers Cohen's unfinished report, which turns out to be anything but harmless.
