Plot
In the late 19th century, the British Empire has become a global power. Due to the strict class stratification, the average citizen has little chance of successfully rising up to the top, where the despicable nobility rules over them all.The first son of Earl Moriarty, Albert Moriarty finds two orphans, Louis and his unnamed brother, that share a common hatred for the corrupt British nobility and adopts them as his brothers. They scheme together to kill Albert's cruel biological brother William, burn down the family estate, and start a new life together using illegal means to destroy the class system, with Louis's elder brother taking William's name and identity.
While enacting an elaborate scheme to murder a noble who was hunting commoners, William encounters Sherlock Holmes, who deduces a third party was involved in the murder. This piques William's interest in Sherlock, leading him to test his abilities by framing Sherlock for murder.
Thus ensues a battle of wits between two of the greatest minds the world has ever seen as William relentlessly pursues a better world and Sherlock pursues the reason why he was chosen by the infamous Lord of Crime to play a part in his murders.

Production
Moriarty the Patriot began as a suggestion from Hikaru Miyoshi's editor to write about Sherlock Holmes after the end of Miyoshi's previous series, and Ryosuke Takeuchi joined after the characters of William and Sherlock had already been established. The focus of the series wound up on Professor Moriarty instead, and Takeuchi has said despite liking heroes as a child, he began to empathize with villains as he grew older.Miyoshi chose to subvert expectations of Sherlock and Professor Moriarty's personalities and create a "gentleman" criminal and a "rough" detective in order to create a story that stood out in a sea of adaptations. Takeuchi commented that every adaptation has a different "flavor" of Holmes, and hoped that the reader could think of Moriarty the Patriot's version as one of the many flavors of Holmes created. William and Sherlock were intentionally designed to be very similar and also contrast each other as opposites as much as possible, in both physical design and behavior.
After the end of the first part of the series, Takeuchi posted a message of thanks to everyone involved in the project on his Twitter account, and updated his bio to indicate his involvement in the series was limited to the first part.
