From the website:
"Taki was educated in New Jersey, at the Lawrenceville School; and at the University of Virginia; and in England at Pentonville Prison, just outside London. See his memoir, Nothing to Declare (ISBN 0-87113-484-5), for details."
The cocaine incident, leading to three months in Pentonville, took place in 1984.

And many thanks for the link to another enjoyable article, Cyrus! I would have missed that one if not for you, so I now must consider myself (choke, gag) indebted to you, if even in a small way.
