Nell was fairly certain that she was being followed, unobtrusively, by at 
least three young men who had locked on to her during her initial passage in 
from the coast, and who were waiting to find out whether she really had 
somewhere to go or was just faking it. She had already made her way from one 
end of the waterfront to the other, pretending to be a tourist who just wanted 
to take in a view of the Bund across the river. She was now heading back into 
the heart of downtown Pudong, where she had better look as if she were doing 
something.
