The Adventure of Charles Augustus Milverton, by Arthur Conan Doyle
Another tale of the Great Detective. It contains Dr. Watson's Crowning Moment of Awesome.
1) Is Holmes justified in breaking the law--either in his decision to commit burglary or his decision in keeping quiet about what he saw in Milverton's home?
2) There's another moral point the story passes over rather glibly: What do you think of Holmes' decision to woo a woman while in disguise, then just disappear from her life after getting engaged?
