The School Badge in the Hand of a Skeleton

Fifteen years ago, a fire in a textile factory killed three female workers. Jiang Che's sister disappeared and her body has not been found. Official case closed: accidental fire. Fifteen years later, Jiang Che became the captain of the criminal police. On a rainy night, a white skeleton was unearthed at the construction site, holding a burned and deformed school badge in his hand - my sister's name was engraved on the back. The medical examiner said: This man has been dead for three years. A man who had been dead for three years was buried under the remains of a fire fifteen years ago. Sister is still alive? Who was burned to death that year? Why did someone let her live without seeing anyone and die without seeing her body? Jiang Che put the school badge back on his chest and began to look through old cases from fifteen years ago. What he didn't know was that someone had been waiting for him to get to this point. Ashes will not be silent forever.
