It is not recorded how the mailman
on Main Street in Los Angeles
tackled the problem in the fall of 1943 - the third year of World War II
. He stood before building #100, where supposably a Mr. F.B.Iers was supposed to be working in room 1619. However, there was neither a Federal Building Company
nor even a room 1619. Somehow, the post card made its way to room 619 where the FBI
maintained an office.
The card had made it past both Japanese and U.S. censors and yet, the FBI had a hunch that there was something more to the text than a reassuring letter and the request to invest some money. If you reads the first two words of each line, you will indeed see a message - "After surrender fifty percent Americans lost in Philippines in Nippon 30%." This was information about losses concealed in what appearers to be a harmless card, and an excellent example of an open code.
