The KGB was planning to wreck the U.S. economy by forcing the biggest banks to dump all their stocks at the same time. A plant in one of Boston's old-money families, and the manipulation of their vast financial power, would trigger total economic collapse. Agent N3 had to discover the identity of the phony Brahmin and make his sudden death look like an accident before the collapse began.
