There are several Sherlockian works that are meant to be used as Canon companions. It is my goal to read all of them, and as I do, I will be reviewing each according to the usefulness and insight provided. Companion reviews are listed in reverse chronological reading order.
Each review is accompanied by a rating system. This rating system is indicated by pipes, with five pipes given for highly recommended books, and one pipe given for mediocre books. Here ratings are based on the criteria stated above.
