A Sherlock Holmes Guide

I found this book in a thrift sales, it cost me a quid or something. So even though my bookshelves are packed, I regret nothing. Its full title is The Sherlock Holmes Book: Big Ideas Simply Explained. It's a guide to all the canonical adventures of Sherlock Holmes. I love reading Sherlock Holmes, but I am not an expert. I do hope that with this book, if I take time to read it, I will become more knowledgeable and learn to appreciate even more the stories I read and loved and see them in a new light.
