Kalliste Periakes is a woman with a past who studies the past. She is also an enigma, a woman who looks exactly like eleven other women in pictures taken throughout more than a century of immigration records, almost as far back as the invention of photography. Is it really the same woman in all those old images? If not, how could they possibly look so much alike? Is she the cause of all this confusion, or the victim of a malicious prank and successful hack into what was thought to be a totally secure government database? Jason Wilson is assigned to track down the hacker. In the process he must learn more about Kalliste Periakes...and about all the other Kallistes.
