Academic librarian Jamie Brodie hasn't seen old boyfriend Dan Christensen in years. When Jamie reads Dan's obituary in the paper, he's surprised. When he receives a letter from Dan, written just before his death, Jamie is shocked. Dan's letter suggests that Dan was in danger, lists two article citations from medical journals, and asks Jamie to look into the citations. When Jamie requests the articles, strange things begin to happen. His computer is hacked, his tires are slashed, he thinks someone might be following him - and he uncovers two more deaths. The coroner's report says that Dan died of natural causes - but did he? Is there something suspicious about the articles, or was Dan just paranoid? The closer Jamie gets to answering those questions, the more it seems that someone is trying to stop him...
