"We do not know all the particulars of your situation—as you know, 
Atlantan subjects are entitled to polite treatment from all branches of H.M.'s 
Joint Forces unless they violate the tribal norms, and that means, in part, 
that we don't go round putting people under high-res surveillance just because 
we are curious about their, er, avocations. In an era when everything 
can be surveiled, all we have left is politeness. However, we do quite 
naturally monitor comings and goings through the border. And not long ago, our 
curiosity was piqued by the arrival of one Lieutenant Chang of the District 
Magistrate's Office. He was also clutching a plastic bag containing a rather 
battered top hat. Lieutenant Chang proceeded directly to your flat, spent half 
an hour there, and departed, minus the hat."
