miadifferent, finalproblem and greensprout for coming up with better references for the crime wall post. I have edited it to add these refs. I'd say, as a reward you get an extra hour in the ball pit, but I'd rather you do more sleuthing on the crime wall or somewhere else in the series. But you know, whatever shakes you boat.
Let's see what we can find about the crimes that Sherlock solved/investigated after his return. From the crime wall:
1. Lion's Mane (Yup):
Sherlock investigated (or at least started looking into) the case of Lion's Mane after he returned. Of course, I might have combined two or more cases in this image. But I am going on an assumption that since the papers are tacked nearly on top of each other and separate from others, they all relate to Lion's Mane. The way I see it is, the photograph next to the news is that of a man, who (most likely same man) is standing by his car at sea-side in the bottom photograph.
2. Trial By Twitter
Trial By Twitter might sound like the case from John's blog, "Death By Twitter", but..um..that one was supposedly before Sherlock jumped. (The "um" and "supposedly" refer to the rather fluid timeline of this show. So, who knows, if it suits the needs of TPTB, the case on the wall might become the same as the one on the blog. But until then let's assume it was a different case.)
3. Monkey Glands latest research
This was of course the case of Professor Presbury and the eventual divorce of the couple who came as clients.
4. MOLE??? MURDER(?) LATE & (Can't read this one properly. If someone can better this, please do so.)
ETA: Thanks to finalproblem, a possible (nay probable - highly probable I say!) candidate is Molsey Muder from The Empty House!
ETA: And thanks to greensprout, I know Molsey is actually a suburb in London! Two people suggesting the same, I'd say the probability inched closer to 1!
5. WAR OF THE WOR(DS/LDS?)
ETA: Thanks to @ladymac111 , one probable candidate is a nod to a pastiche Sherlock Holmes’s War of the Worlds. It's a crossover between Sherlock Holmes, War of the Worlds (by H. G. Wells), and Professor Challenger (protagonist of Lost World by Doyle)!
6. Cereal Killer
7. Dressed to Kill in blue rectangle.
(This is not readable in this frame, but later on when Sherlock is checking the wall just after Mycroft has left, we get a close up of the wall, where it is readable.) Whether this is a reference to the movie by the same name (an erotic murder mystery) or to the book "Dressed to Kill: James Bond - The Suited Hero", well, it's upto you to decide. Since S3 did have at least one reference to James Bond (the blunt instrument), maybe it was the later.
ETA: Thanks to miadifferent, it could very well be the reference to the Basil Rathbone movie "Dressed to Kill"!
8. The green rectangle most likely says "The Show AXED", but I'm not at all sure.
TL;DR: I see reference to Lion's Mane, but if someone with access to Blu-Ray might want to confirm not just this but all of these. Also, by the time Sherlock's parents arrive at 221B, the scrapbooking has extended on both sides. Again, if anyone (is interested and) with Blu-Ray access want to check those, please let me know.
ETA: Have an extended crime wall, thanks to mid0nz!
