I really like 'A Different Path'. This fanfic takes a unique turn by changing some of the events in the original story. It shows an alternate version of Moriarty's plan and how it affects the other characters. The writing style is engaging, and it keeps you hooked from start to finish.
A good 'Moriarty the Patriot' fanfic should first and foremost stay true to the characters. For example, Moriarty is a complex character with his own motives and beliefs, and any deviation from that without proper explanation can make the fanfic feel off. Also, the plot should be engaging. It could be an alternate take on the story or a deeper exploration of a certain aspect like the relationship between Moriarty and his brothers.
Holmes said to Professor Moriarty,"
I understand what you mean, Professor Moriarty. But I want to point out that my reasoning process is not based on speculation or bias, but on evidence and logical reasoning. I don't need to guess or have the courage to guess to reach a conclusion because I can reach a conclusion based on the known facts and evidence in the scientific method. So please do not try to mislead me because I have the right to obtain all the necessary evidence to support my conclusion.
