They approach a nearby boat with no one on board; in the cabin, documents of diver Sonia Lalande, a nurse, and a map with a mark at Pointe du Lion; scuba bottles marked "La sirène bleue", a local diving club. Nadia confirms death by drowning, but remains show drowning occurred on board in a washbasin full of water. Étienne Porchet, owner of "La sirène bleue" confirms that Sonia had sailed in his boat the day before with Fabien Deville, one of his monitors and also her boyfriend. They were searching 18th century shipwrecked galleon San Fernando. Fabien becomes main suspect: both he and his motorcycle have disappeared and the brigade thinks he has escaped with the treasure.
