"Recognized the fist," Waterhouse says. "So, this is the spatial arrangement of Azure transmitters—not counting the stations in Europe that are making Pufferfish transmissions, and hence, according to Assertion One, are part of the same network. Anyway, now let us say that an Azure message originates from Tokyo on a certain date. We don’t know what it says, because we haven’t broken Azure yet. We just know that the message went out to these places." Waterhouse draws lines radiating downward from Tokyo to Manila, Rabaul, Penang. "Now, each one of these cities is a major military base. Consequently, each is the source of a steady stream of traffic, communicating with all of the Nipponese bases in its region." Waterhouse draws shorter lines radiating from Manila to various locations in the Philippines, and from Rabaul to New Guinea and the Solomons.
