In December, I went to Moscow to look further into the Litvinenko Affair. The Prosecutor General's office had set up a special unit, the National Investigative Committee, to handle that and other sensitive investigations. It took a resourceful research associate, and a few weeks of vexing paper work, to arrange an appointment. But, once in the door, its investigators proved surprisingly cooperative.
