"It's a little daunting to see how much work the show's makers put into these little Easter eggs for fans, and it's even more so to imagine how much time Frankel spent finding them all" - Rambles.Net

 
I thought I was reasonably knowledgeable about the Doyle canon--but I couldn't come close to the detail in this little book! I can't wait to watch the shows again, and read along to catch every little reference. Fun for all Sherlock fans--and all Obsessive-Compulsives who need to know absolutely everything about Holmes." - Sherry B, Amazon.com Reviewer
