Hanssen's motives were curious. He was a devout Catholic and member
of the reactionary Opus Dei, and also had some unusual sexual interests --
a combination that produces conflicting speculations. The U.S. paid out
$7 million to a defector who furnished Hanssen's file from a well-guarded
building in Moscow, and then resettled him in America. Hanssen's name was
not in the file (Hanssen never told Moscow his name), but his fingerprint
was on a plastic bag retrieved from a drop, and his voice had been recorded.
For three years the CIA and FBI investigators knew they had a mole problem,
and had quietly focused on a CIA officer during that period. When they got
this file they discovered that they were pursuing the wrong man.
