If anyone's wondering, it was the money and lifestyle far beyond his salary and the physical geography of the payment drop-offs that betrayed Hansen. Also, if I'm remembering right, one of his in-laws (?) suspected him in the early 80s and tried to alert the authorities but was long ignored. (Don't have the book anymore. It's part of the extended-family mobile lending library system.)

Googling around, I'm reminded that the real tipping of the case to Hanssen (double s) came when an ex-KGB official sold Hanssen's Soviet intelligence file BACK to us, including much of the original materials from the drops. As I said, the Russians themselve's didn't know Hanssen's real identity. Nevertheless, Hanssen's prints were on garbage bags which the Russians had thoughtfully kept and which were returned in response to the request for "everything."

Well, I said I didn't have the book right in front of me anymore.
