"The cine stat could track him only as far as the gates of New 
Atlantis," Miss Pao said. "His face was bloody and swollen, complicating 
identification. He had also been tagged, naturally—the tagger aerostat 
cannot make any distinction between victim and perpetrator—but no spores 
were received; we can assume that all of his tag mites were detected and 
destroyed by Atlantis/Shanghai's immune system."
