Several Jeri class androids begin committing "suicide" and Section 9 is called in to investigate.  They discover that a maintenance routine has been infected with a virus.  The virus has a security code though which suggests that the writer has a Jeri that they want kept from harm.  They track down the man who turns out to be the son of a Canadian diplomat.  He's evidently got a thing for the Jeri and wants his to be unique.
