In 1977, when the Cold War was still going strong,  I got involved in an incident with a Soviet spy in a government research laboratory in Canada. My name was kept out of the press at the time, but I think enough time has passed, Glasnost has come and the Cold War is over, so  it is probably safe to go public.

On the other hand, if I suddenly go down with Polonium poisoning, you will know what has happened.
