Cyrus lost his index finger in a freak accident and settled for a desk job with the Hong Kong Police. Reluctantly, he started an AI project using Natural Language Processing to predict suicidal trends. The engine picked up and classified social media posts into five categories: Rose, Ruby, Scarlet, Crimson and Cardinal. At Cardinal the highest level of alert, the targets were deemed mathematically ready to take their lives. Through this experimental project, Cyrus and his team saved many individuals, until things got a little more complicated when one unstable target intended to take 12,000 innocent lives along with him.
