I'm trying to recall a book that I read as a paperback somewhere in the 1995-2005 timeframe.
- Protagonist is a genius, exhibits some spectrum behaviors
- Protagonist's life is deeply affected when, as a child, his brother is kidnapped and murdered; possibly living in Concord, Massachusetts at the time
- Protagonist grows up fascinated with criminal forensics
- Protagonist creates
recordinglie detector technology through which everyone's life is recorded 24x7 from their viewpoint Recordinglie detection becomes both mandatory and discoverable as evidence
recordinglie detector technology revolutionizes criminal forensics and ushers in a golden age where crime drops precipitously
Near the end of the book, the unscrupulous business partner of the protagonist threatens to blackmail protagonist with knowledge of a crime protagonist had committed years ago; protagonist chooses to murder the partner, taking advantage of a backdoor protagonist had left in the
recordinglie detector technology to allow it to be evaded.
Any help identifying the book would be greatly appreciated!
[Edit: Following @JoeL.'s correct answer, I corrected the question so as to not to be misleading for future searchers. Mea culpa!]
