Today, we have a tale that has been etched into the annals of Cold War espionage, a story that played out not in the bustling metropolises of Moscow or Washington, but in sunny Sydney, Australia.

There's an abrupt abduction - a struggle, a flight - a desperate race to the airport. The plane is waiting, engines humming, ready to spirit her away back to the motherland. But as Evdokia is hastily ushered up the stairs of the plane, something falls onto the tarmac. A single, simple, black shoe.
