Help finding an old friend?

Hello:
I am trying to contact an old friend now living in Cannes. I have an address, and a telephone number, but I'd rather try to find out if it is possible to contact her by e-mail. Is there anyone living in the Cannes area that would be willing to help me. I've become far too used to e-mail to even try find a place to buy Airmail stationary and try to contact her that way.
Thanks!
P.S. I now live in New York, I think that we have an eight hour time difference
