Conan Doyle used a historical incident he read about as the basis. It wasn’t based on an any axe to grind, just something exotic in 1887 London. Conan Doyle later made that clear. He privately expressed this to Brigham Young’s great nephew.

I suspected as much from the context and the style, and Doyle's general reputation as a tolerant fellow.

Glad (but not surprised) to hear that he confirmed that w/ Young's family.
