I thoroughly enjoyed MYCROFT, so the sequel was a no-brainer. And Mr. Abdul-Jabbar and Ms. Waterhouse did not disappoint. Now that we're well acquainted with Mycroft, it was so fun to see his fraught interactions with Sherlock. Oh, and Sherlock as a young man! Simply the most exciting.
As a fan of (almost) any Holmesian writing, this one is high on the list of well-written and well-thought out contributions. This book is not just a vehicle for the Holmes brothers either; there is a fair amount of social commentary on Victorian England as well. I applaud these writers for a job well done. I recommend this sequel highly - it might even outpace the first!
