Doublecross
His fingers
Her legs
Learned this with the War of the Worlds broadcast. Either very beginning or very end (been a long time) announcer says …xx… telling all those "in the know" that the information was FALSE.
also,
The Double-Cross System or XX System was a World War II counter-espionage and deception operation of the British Security Service (MI5). Nazi agents in Britain – real and false – were captured, turned themselves in or simply announced themselves, and were then used by the British to broadcast mainly disinformation to their Nazi controllers. Its operations were overseen by the Twenty Committee under the chairmanship of John Cecil Masterman; the name of the committee comes from the number 20 in Roman numerals: "XX" (i.e. a double cross).
That's why–his fingers, her legs = picture is FALSE
