In a case as bizarre as it is unusual, two French journalists were last month arrested in a luxurious Paris hotel on suspicion of the attempted blackmail of Morocco's King Mohammed VI. Éric Laurent and Catherine Graciet are accused by the Moroccan authorities of demanding 3 million euros in exchange for not publishing their book of damaging revelations about the Rabat regime. Mediapart has obtained access to documents from the French judicial investigation which demonstrate that the case is far more complex than it first appeared. Sting or set-up? Michel Deléan reports.
