Zis is surely a case for Inspecteur Poirot-non? Ze disappearing Coticules - stolen by a petite homme who spoke with a distinct Belgian accent. He was last seen walking away, very slowly, wiz a grande bag slung over his shoulder.
Ze Belgian police have reqested that their French neighbours put Inspector Cleuseau on ze case to help as well.
I hope to keep you well informed of developments. In ze meantime if you see a big hone offret at small prix - please contact the Begian consulate.
