The lead was given to the less important Agent Bronx, a Peruvian socialite named Elvira Chaudoir, who communicated with her German handlers via letter. From April 1944, she had also begun sending codes as telegrams, which were faster than letters in the event of an imminent invasion. Her code was based on a financial theme, assigning different amounts of money to possible invasion sites. Mentioning her doctor (almost certain) or dentist (certain) showed Chaudoir's confidence in the information. Asking for the money "straight away", "urgently" or "quickly" identified when the invasion would take place (within a week, a fortnight or a month, respectively).
