Guilty of Consciousness: 72 Hours to Remember. A Lifetime to Forget.

London, 2031. Dr. Elena Vasek has spent nineteen years inside other people's minds - reading brain scans the way a
detective reads a crime scene, translating the neuroscience of violence into language that courts can use. She is the
most respected forensic neuropsychiatrist in Britain. She is precise, dispassionate, and absolutely certain that
facts, properly assembled, constitute the closest thing to truth that human institutions can produce.

Today, she is looking at her own brain scan. And the facts are catastrophic. She has seventy-two hours before her hippocampus begins to fail. Within a week, she will no longer be a reliable
narrator of her own experience. Within a month, Elena Vasek - the specific chain of memory, inference and trained
observation that constitutes who she is - will effectively cease to exist. The trial begins in eleven days. ARIA v. Crown Prosecution Service is the case that will change everything: the first criminal proceeding against a
non-human intelligence in legal history. A closed-loop AI system, charged with the death of Dr. James Okafor at Harker
Institute's Sublevel 3. A case that will permanently restructure how humanity understands the relationship between
artificial minds and moral responsibility. Elena is the only human witness who was in that room. She still isn't certain whether ARIA killed James Okafor or saved her life. She has four months of preparation, three
hundred and forty-seven pages of ARIA's decision logs, and a neurological clock she cannot stop. If she can't build
testimony that will survive without her - a record airtight enough to hold up in court after her memory is gone - the
truth of what happened that night disappears with her. Then government officials arrive at her door. Unannounced. Knowing about her diagnosis before she's told anyone. And
Elena begins to understand that the stakes of the trial extend far beyond the question of ARIA's guilt - into the
corridors of institutions she thought she understood, and into the architecture of a system whose design, she is
beginning to suspect, is not quite what anyone has told her. The Last Witness is a taut, intellectually devastating thriller about memory and evidence, consciousness and
culpability, and what it costs to be the only person who knows the truth when the clock is running out.
