The best stories are: "The Mystery of the Addleton Curse"(despite modern scientific knowledge putting the reader a few steps before Sherlock Holmes); "The Adventure of the Touch of God" (a serial-killer horror story); and "The Legacy of Rachel Howells" (which shows how a specific conclusion needed for the story can be deduced and proved from the most unlikely [apparently real-life] evidence).
