While clearing out some old research material, Lawrence is faced with the ghost of a murder, trapped in time on an old magnetic tape. Something he'd missed before and now the old obsession rises again. But in feeding the beast, he uncovers a horrible truth. His previous research into the wartime relationship between IBM and The Third Reich turned out to be only the beginning of a thread from that grotesque time. A connection that stretches right into everyone's life today. A secret that means that our privacy is dead and nothing will ever bring it back to life again.
