[Western Crossover] How to Successfully Capture a High-Functioning Sociopath

This story is set in the worlds of Sir Arthur Conan Doyle, the BBC, Harry Potter, and the Marvel MCU, mainly the BBC's Sherlock universe!

The characters belong to their original creators, though. If I write them out of character, please go easy on me!

Daniel Rumlow is conducting an experiment. He wants to capture a high-functioning sociopath, and of course the great detective will have to cooperate. How could he let such an interesting person get away? He has to keep him firmly in his grasp!

P.S. This foolish author is tempting fate again. Starting one story after another like this, I'm going to end up burying myself in unfinished projects!
