Okay, the series is starting to pick up a little bit. I really enjoyed seeing John and Sherlock interacting, and I really like how Sherlock's personality is done in this adaptation. 

And I also really enjoyed seeing Fred and Louis's respective characters get developed a little more.

I thought it was interesting how both of them have a certain distance from William, considering that one is his own brother and the other is his subordinate. There was a little side comic at the end of one of the two previous volumes that touched briefly on Louis feeling like he doesn't really do much to help his brother achieve their shared goals, and I was wondering if they would touch on that again or if it was just a one-time joke. I hope this is explored more.

Might be over thinking this, but the cover of volume 1 features William in front of a red background, and volume 2 features Sherlock in front of a blue background... Volume 3 has Louis in front of a purple background. Is this foreshadowing Louis some kind of future plot point where Louis wavers?

This was a little hard to get through because of certain aspects of the subject matter, so please look at the content warnings to see if there is anything you can't stomach.
