There had to be another explanation. Sam’s program continued to run as he pondered the riddle. While his own icon remained stationary among the tumbling alphanumerics, nearly transparent because his cyberterminal was engaged in a "flow-through" search, the Jiro icon passed him. It gave no sign that it noted his presence, no hint of recognition. Sam felt simultaneous disappointment and relief. Even a ghost of Jiro could not have passed without acknowledgement. Whoever was using Jiro’s icon was a stranger.
