THEMIS: DUTY TO WARN
Guy Morazain
A Montreal synagogue. Three dead. Four, counting the shooter.
A radicalized student with no apparent motive. An AR-15 that crossed the Montana border without a record. A Montreal AI company two weeks from its IPO — one that may have had the information to prevent the attack.
Daniel Tanguay is a journalist who sees patterns others miss. He is also high-functioning autistic, methodical, and in possession of an AI system called Alice that most people would find difficult to explain and impossible to replicate. When a former Mossad operative passes a warning to his retired military intelligence contact — a warning that arrived too late — Daniel pulls on the thread. He expects it to end in Calgary. It doesn't end there.
The investigation takes him from the streets of Montreal to the backrooms of Calgary, to a safe house in Kingston — and eventually to Kraków, where a network with no ideology and no fixed allegiance has been operating in the shadows for decades. V.O.SS. sells capability. Someone bought it. Someone pointed it at a synagogue in Montreal and walked away.
Standing at the centre is Victoria Wei, founder of Cassandra AI, whose company holds data that could have prevented the shooting — and whose IPO is now leverage in a game she didn't know she was playing.
Daniel knows what he has found. The question is what to do with it.
THEMIS: DUTY TO WARN is a crime novel set in Montreal, Ottawa, Calgary, Kingston, and Kraków, built around a cast of morally serious characters navigating a world where information is both weapon and obligation — and where the line between knowing something and acting on it is the only line that matters.
