WORD ORIGIN
There are several theories regarding the origin of the expression double-cross, none of which have ever been confirmed.
In his book, A Man Called Intrepid, William Stevenson claims that the expression originated with the Double Cross System, a British military World War II counterintelligence operation. Apparently, the committee that ran the operation, whose goal was to turn known German agents into sources of disinformation, met regularly in room 20 at headquarters. The number on the door to the room was written in Roman numerals, hence XX. Stevenson writes that the committee members began calling themselves "Room 20," and finally, the "double-cross" operation.
Another theory is that double-cross began in London during the 18th century with a 'thief-taker' called Jonathan Wilde. In the days before regular police service, thief-takers were paid to deliver criminals to the court. Wilde got his information mainly through informers, often criminals themselves who Wilde protected as long as they were of use to him. Wilde marked each of his informants with a cross in a book. If they failed to supply enough or the right information or could no longer pay Wilde for his silence, he added a second cross and delivered them to the magistrates for trial. They were then double-crossed.
