Typically, the main character is the assassin themselves. They are often highly skilled in combat, stealth, and have a sharp mind. For example, in many Hidden Assassin novels, the assassin might be a lone wolf type, like in 'The Silent Assassin' where the main character, Kai, works alone and has his own code of honor.
The Hidden Corner is a horror film because it contains some horror and horror elements such as darkness, loneliness, despair, strange atmosphere and unknown threats.
