A Chinese official who's a friend of Jameson comes to New York to locate three men who during the war approached him and offered him money for secrets about Mao. Which he refused. But now it appears the incident is being investigated and he needs to find one of them to verify his innocence. He asks Jameson to help him find them but he wants it done quietly because it seems that there are elements who want him convicted, so Jameson asks Peter Parker to talk to someone in the military to find them discretely. But it seems one of those elements is an industrialist who is among the ones being considered to build a power plant in China that's worth a billion dollars, and the industrialist knows that the official is considering another company but if he's convicted he knows that his successor will award the contract to him. So he sends someone to make sure he doesn't find his witnesses or make sure he doesn't return to China alive.
