Sherlock Holmes is a detective that needs to introduction. His Mysteries have captivated audiences for over 100 years. A Study in Scarlet is the original. This is where it all began. We are introduced to Holmes, and as a part of the story Watson and Holmes are introduced and proceed to begin their journey. The mystery in this case is a murder that takes us around London and dives into a love triangle as well as various religious aspects of life. We learn about Holmes' way of reasoning through a crime scene, and his skills are already impressive although inexperienced compared to what comes later. The story is fantastic, and this is where Sir Arthur Conan Doyle was just learning his craft. This book launched a career that has entertained readers for generations and hopefully will entertain audiences into the future. The Annotations in this book are meant to help the modern reader with some of the more dated language. The story in this book appears exactly as it originally did. The annotations are left as footnotes on all of the relevant pages and it is my deepest hope that they add to the enjoyment of the story.
