I chose to deal with the science of cryptography. Cryptography began in mathematics. Codes were developed, even from Caesar's time, based on number theory and mathematical principles. I decided to use those principles and designed a work that is encoded.

What affected me most profoundly was the realization that the sciences of cryptography and mathematics are very elegant, pure sciences. I found that the ends for which these pure sciences are used are less elegant.

When I accepted the commission, I had something of an epiphany in the research I did about the agency, actually the science of espionage. I realized there is a connection between the sciences and the invisible forces of man.
