For readers in Cassis [only!]

If you happen to be in Cassis or nearby, and have time and will to do so, could you please check with the Police Municipale there whether or not they have been  brought a pair of black prescription Demetz Ros 11 sunglasses…?! I lost them around the main street of Cassis last Tuesday and the only way to check whether anyone dropped the glasses at the police station is to get there! Since they are brand new, following the loss on the Ardèche in May, and useless for anyone else, I would appreciate immensely!!!
