One more thing, Sotheby's, being a publically traded company, does have other avenues of recourse. I'd begin a professional letter writing campaign to the Board of Directors.

Following that, I'd be talking to my local FBI agents. They seem to be interested in fraud in the collectibles industry.
Am I mistaken, or are you in Southern Florida?
