Russian happens to be one of the nine languages Droujinsky speaks, but the job also required agility and urgency. ... It was an open secret in Washington that the FBI wiretapped and watched the Soviet Embassy, though a number of would-be spies either were unaware of that or thought they could avoid detection by concealing their identities. ... I first heard from an intelligence source in the mid-1990s that the FBI had a “fake Russian,” and I had chased him ever since. An FBI contact of mine cautiously confirmed that the bureau had an agent who impersonated a KGB spy handler, but would say no more. After I discovered his name buried in a news article about a court case, I found it in a phone book—a seeming stroke of luck, since most FBI agents are unlisted. But when I called the number I got his son, who has the same name. The son agreed to pass on my request for an interview, and eventually relayed his father’s reply: Sorry, but no. ... I asked him why, after all these years, he had decided to talk to me. “I’ve been out of the bureau for many years,” he told me, “and I didn’t think it would jeopardize anyone.” He deflected my offer to meet at his home, but unlike other counterspies I have interviewed, he said I was free to quote him by name. One lunch led to eight more; over ten months, the FBI’s bogus Russian discussed his life and career with a reporter for the first time.
