Just got done reading the first book of the original Sherlock Holmes series, A Study in Scarlet. I gotta say, it was quite interesting to see how things worked out. Apparently the murderer was after Mormons for killing his love interest, as his love interest, Lucy, had converted to Mormonism to save her life, but then, when it came to the time she HAD to be married, she decided to run away with this man and her dad.
Her dad was killed, and when she was married to one of the guys who had many wives, she died a week later fro grief. Thus, the suspect followed the two Mormons responsible for both Lucy and her father's deaths, which led him to killing them.
Overall, good story. Although, I wonder why Doyle chose the Mormons to do such horrendous things to people, though.
