リチャード・マッデン
As the story begins, Doctor Tsun has realized that an MI5 agent called Captain Richard Madden is pursuing him, has entered the apartment of his handler, Viktor Runeberg, and has either captured or killed him. Doctor Tsun is certain that his own arrest is next. He has just discovered the location of a new British artillery park and wishes to convey that knowledge to Berlin before he is captured. He at last hits upon a plan to achieve this.
