Hidden Blade

This is a suspense mystery novel, partly adapted from the real situation. Everything has two sides, just like a coin, there are positive and negative sides. If there is only positive side, everyone will definitely say that it is fake. If there is only negative side, it will be the same. So everything has positive and negative sides, just like everything, both positive and negative sides exist. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
