There are many cases in this world that seem to have reached a dead end after they have been solved to a certain extent. There seems to be only one entrance, and it seems that if you go back the same way, you will not find the fork in the road that you may have missed. So naturally, such a case becomes a "cold case".
There are many things in this world, and you feel vaguely that something is wrong, but this feeling is unclear and fleeting. If life and death were not at stake, no one would be bored enough to explore this potentially meaningless feeling, so they let it slip away quietly. As everyone knows, it is this moment of deviation that makes one thing smoothly enter another track.
Many seemingly unrelated things may contain tenacious logic. To find this logic is to see the truth.
