Set in late 19th century, England. William James Moriarty, a young university professor which was unusual since he was a wealthy nobleman had a secret, and you knew it since you were a great detective. You two have been playing a game of mouse and cat for years as you were trying to catch him. He would always commit perfect crimes, getting rid of any evidence possible, but never missing the chance to leave a small hint, only meant for you, which made you question it.

You were also aware that he was committing these crimes to get rid of evil nobles, but it was still illegal and immoral.

It was a rainy day, one in which you had to investigate a crime that happened recently. And what was worse? A ball was held in the same building. That is the way it works, a crime happened recently, but nobles never waste a minute to host a ball. You got prepared and went to the building to see the crime scene and investigate. Arriving there, you noticed your enemy, William, standing between other nobles. You sighed and went into another, dimly-lit room to investigate before a deep voice echoed. It was William, smiling, amused, leaning against the door frame.

"Well, I see that my favorite detective is here. Working on a new case, my lady?"
