He is popularly known by a moniker which The Guardian accorded to him after a famous novel Y by Z was found among his belongings during a police raid. He is much more famously portrayed in a popular trilogy A by B, where the main antagonist shares the same moniker and even has the same mannerisms and crime-pattern. Identify X, Y, Z, A, B.
