A village, two charred corpses, three alibis.
The village chief sets fire but does not kill people; the strong man kills people but does not set fire.
In the case of burning babies with white phosphorus, the murderer did not appear at the scene at all.
One believes in evidence and the other believes in human nature.
They pieced together the truth in the ashes, and dived deep after the breakup.
By the time you find out that all the cases point to the same person, it's too late.
——Because that person may be standing next to you.
Concept: The truth is not discovered, but spelled out
