Summaries:

1. The Ninth Muse - Conspiracy and murder find Sherlock Holmes and John Watson surrounded by covert enemies in the heart of Scotland Yard. Together, they unearth clues that illuminate the scope, depth, and distorted psychology behind the crime! And, after a pre-emptive strike ordered by the mastermind they pursue, Holmes elects to continue the investigation under conditions that will force John Watson to fight for his friend's -- colleague's -- life.
2. The Photography Club - An evening out is interrupted by a cryptic call from Lestrade, and the doctor and Consulting Detective are greeted at Scotland Yard by CIA Agents looking to work with Sherlock Holmes. The Agency needs to leverage Sherlock's unorthodox knowledge of London while investigating a missing CIA mole they presume dead... only it's proving tricky to identify the body, and even more of a challenge to unravel the mystery behind the murder.
3. The Burning Question - Hot on the heels of solving a missing person's case, Sherlock finds Lestrade and John at the door. Downtown London is burning and no one knows exactly why. But who better to tease a pattern from utter chaos than Sherlock Holmes?
4. The Double Walker - With John caught in the middle of staffing changes at the clinic, and Sherlock's boredom reaching ever more grandiose heights, it was the right time for a case. A missing corpse and a crime scene so bloody it's impossible the victim could've survived means there's more than enough to keep Sherlock occupied, even before it becomes clear this victim is no stranger. Can Sherlock and John interpret three words, left as clues, in time to catch the culprit?

I went ahead and put all four stories in one thread. They can be read as stand-alones but they read best in order, as in some cases something that came up in an earlier story will make an appearance in a later one. They can also be found on fanfiction.net under the same author name but I linked to the other site because it has a "collection" page and I'm lazy.

They're not perfect, but they are probably the best non-crossover Sherlock stories I've read. There's no slash. The author obviously plays favorites with some characters. Sarah takes on a larger role as John's girlfriend and becomes a secondary character on par with Lestrade or Mycroft from the TV show. Mycroft has very small roles and some of them don't quite seem in-character for him. Lestrade is less buddy-buddy than he was at some points in the TV show and the copper aspects are played up a bit more, but it works. Molly is almost non-existent as it seems the author wasn't too fond of her. I can't even remember if Mrs. Hudson made an appearance.

Some of the stuff is... strange. I wasn't a big fan of the "Think Tank" in the second story, but it was established that Sherlock was naturally better than them so it worked out. Also wasn't too fond of Mycroft in that one, but whatever I suppose. There's a lot of minor things that bug me like that. Or like John and Sarah still not having slept together despite all the stuff that's been going on. But on the whole...

The mysteries, action, and characterizations of John and Sherlock are quite good. That's what carries the show, and it's what kept me reading. Well worth a read. HP fanfics of this quality would almost certainly make the library.

I think it's roughly a 4.5 and overall a solid 4/5 for the series.

Edit: I talked to the author a bit on fanfiction.net in response to some of my reviews, and they seem pretty cool. Addressed some of the things I mentioned in my reviews, discussed the stories, etc. So kudos to the author for being good about that sort of thing.
