That evening, an encrypted telegram was sent from the radio station at the Sevastopol Fortress. After a "long-distance journey" of more than two hours, it arrived at the underground telegraph room of the National Intelligence Bureau at midnight.
The intelligence officers receiving the telegram listened to the audio signals from the radio station while using a pen to transform the signals into letters recorded on slightly yellowed paper.
After a while, the ticking of the radio stopped, and the intelligence officer handed the transcribed telegram to Marcel Yale.
Marcel Yale locked the door upon receiving the telegram and looking at the densely written characters on it.
Then he went to the desk, took out a book almost identical to Jerome Bonaparte's, and page by page compared it with the characters on the telegram.
Soon, Marcel Yale translated the content of the telegram again and wrote it on the back of the telegram paper.
