Well I just heard from Marie this morning and she received an email from Pere Lachaise saying that the thieves had been caught. The "theft ring" was a mother, son and daughter, who were apparently trying to sell the stolen busts and medallions at some of the, shall we say less-inquisitive antique dealers in Paris. marie said that details so far are sketchy but that thery recovered quite a few busts including Bizet.
The good news that the string of thefts of wonderful works of art has been brought to a halt, at least for the time being (we hope).
The question now is what will the city do about protecting all the busts in the cemetery in the future? Certainly one alternative would be to increase foot patrols of police and the cemetery wardens. Another, more effective but certainly more costly option would be to take one of the existing buildings in division 83 for example, presently used for administrative purposes, and turn it into an exhibition hall.
