 Krishnan′s story of business ambition leads to the story of an entrepreneurial Chinese trading family who arrange the transferring of the arms.
 The central, third story features an American couple, Greg and Dorothy Nilsen, who are tourists of the Far East used to legitimize the transaction, and so find themselves in great danger — the recurrent theme of ″innocents abroad″ that characterizes the novels of Eric Ambler.
