and this is important...a clue left but to what?

it is likely to be the road...

6, rue Pablo-Néruda, Bagneux, France

Villenave d'Ornon 33140

oh I remember now...varenne...French intelligence telling me "nothing we can do" basically...and why, I might ask....

and the name VILLENEUVE or something like it...and also a French politician at the time...on tv quite a bit...circa 2001....what was his name again...before he became prime minister...it had been VILLEPIN hadn't it?:

Villeneuve must have been in French intelligence....and Villepin was around at the time....varenne...that is all I can remember....

although as far as I know...ling will be looking at this man:
