"Do you want to see Gough Whitlam's FBI file?" I said, walking into the other room where my wife was reading.

"Yes!" she said excitedly. My wife's Australian, and she knows I've been obsessed with figuring out what the FBI and CIA knew about former Australian Prime Minister Gough Whitlam's bizarre ouster as leader of the country in 1975. Whitlam's FBI file could hold clues to a mystery that's still as confounding today as it was 40 years ago.
