Fei Chengan: When someone commits a crime, and even before and after the crime, their body involuntarily secretes pheromones, also known as external hormones. I happen to be able to smell them and identify the intense emotions associated with each scent, such as the fear of committing murder, the excitement of a sadist, or burning hatred. In other words, I can smell evil.
