I must warn however that if that theory is true, especially the part about Gin, it might really spoil the end of the story, and you might regret having read this.
That said, here comes the theory:
Spoiler:
There are a lot of intelligent people in DC. Most intelligent ones are on par with Conan. It's obvious with Heiji that is Shiniji's clone, with Akai where they seems to think the same thing in the same time. It's also true with Vermouth were it seems sometime one has lead, other time, the other has lead.
But there are two people that really seems to be way above Conan/Shinichi in term of deduction. Yuusaku and Gin. they both seems to have 2 or 3 plans ahead of Conan. They are both scary guys.
When Yuusaku was first introduced, it was still like it was Conan versus BO, and Yuusaku is a busy man, so as BO is Conan's problem, it made sense at that time that Yuusaku would let him solve the mystery alone.
But it has been some BO arcs now that it's clear it's not Conan versus Gin or Conan versus BO, but it's Conan's team versus BO team (as stated by Yukiko/Vermouth in the Mystery train arc). Yuusaku would clearly have a place in Conan's team. His not involvment seems strange in fact if you take into consideration the fact that Yuuki on the other side is ALWAYS involved in BO cases. And generally he is often by Yuukiko's side when it's not BO related, but never by her side when it's BO related.
Any way, I think Gamma theory beeing true or not, Yuusaku is involved in a way or another in this, pulling the strings from behind the scene, and he will appear in the last BO arc.
"There is nothing like a silver bullet that can destroy the whole organisation in one shot". That's typically something that a silver bullet would say.
Gin ? A silver bullet that wants to destroy the organisation ? And what if Gin is... Yuusaku ?
Ok, that's crazy and that doesn't even make sense... until you analyse this fact by fact.
Ok, so why Yuusaku/Gin would destroy the BO, he's the most loyal servant. Well, no one even said that Gin was a loyal servant of the BO, we all assumed it because of his actions. But if he's infiltrating the BO, he won't come and says "hey, look at me, I'm the suspicious guy !". Of course not.
And as the Boss beeing cautious and suspicious (otherwise Yuusaku would have stopped the Boss long time ago), it's probable that Anokata doesn't trust Gin (We all assumed that Gin being that cold hearted, the Boss would trust him, but can you find me a concrete proof that the boss trust Gin ?), and Vodka would be someone put on Gin's side to spy Gin and report his actions to the Boss.
Ok, so why would Yuusaku/Gin try to kill his own son ? That doesn't make any sense ? Well, it doesn't make any sense if the drug would have killed him, but if Yuusaku/Gin knew the drug would have only shrunk him, he's clearly the kind of father that would do it to make a new powerfull pawn enter the checkboard : Conan.
Well, how would he know ? Shiho wouldn't even have predicted it. Well, what if the drug wasn't made by Shiho but by Elena and/or Atsuhi Miyano.
Somehting happened to the Miyanos some years ago. We don't know what, they are assumed dead but we don't even know it exactly. What if they went in contact with Yuusaku, something like 10 years ago (that can be another time). For example, they tryed to escape the organisation by leaving a crypted message somewhere that only Yuusaku was able to decrypt and understand. Then he decided to make them disapered by leaving them dead, but he couldn't do it for the children, Akemi and Shiho. He then entered the BO as Gin to help the children evade and to take down the BO.
So in the attraction park, Yuusaku/Gin gave Shinichi a drug he knew woulnd't kill him but only reduce him (in the size that Yukiko would love to see but that wasn't the goal) made by the Miyanos (or only Elena or only Atsushi ? We still haven't any clue on their relations).
All the speech about killing him with a new drug was directed to Vodka in order to make a decent story for Anokata.
So now you can reread every BO related chapter, and you'll see another story. That someown make sense ! Gin tracking down conan hidden in a locker until he reached the right locker and then said "that can't be, an adult can be hidden here" make perfect sense ! It's just Yuusaku trolling his son like he always does, while being pro and even over-pro to the Vodka eyes.
So Akemi would not have been killed, but rather "freed from the organisation". Yuusaku/Gin just tricked both Vodka (easy) and Conan (well, if someone can do it, it's clearly Yuusaku) into beleving she was dead.
Did you notice that Gin rarely kills despite being so "Cold" ? You can see it as him not wanting to do unnecessary things, or as him being Yuusaku.
Yuusaku and Gin both have "attributes" on their faces. Yuusaku have glasses and mustache and Gin have a turtleneck sweater, a hat and long hairs. They all mask different parts of the face. Moreover, the turtleneck sweater is the perfect place to hide a voice changer made by Agasa Akase. Yes that old racoon would be an accomplice as the Yuusaku's Watson it has always been. (Him beeing Atsushi Miyano is nice, but perhaps a bit too much and doesn't fit with the Fusae part, even if you consider Fusae beeing Elena)
Imagine what could happened in the future... It's the last BO arc. Conan's team have the upper hand. As always Yuukiko is involved. Gin is about to get trapped somewhere. Anokata is around somewhere, it's just a matter of time that Anokata will reveal himself/herself. And then, Yuukiko is suddenly betraying Conan's team to side up with Gin. Everyone is shocked, from Conan to Vermouth and Vodka... End of chapter... You have to wait to the next week to have the following chapter. Wouldn't that be cool ?
Yes except you'll hate me "Ho, I shouldn't have read that Gamma Theory!", but hey, you've been warned !
Ok so that all for today for Gin. And now, if Yuusaku is already deeply involved with the BO case, does the ICPO (Interpol) officer that Yuusaku evoked in his introduction case real and already involved too ?
Well... If the 2nd best student of the police academy gets to go the to prestigious First Division of Tokyo Metropolitan police, where would the 1st best student gets to go ?
Wataru Date was the archetype of the good guy/good cop dying in duty. And that guy had some kind of respect for Amuro. Moreover, that respect seems to be mutual (Amuro keeping a text message from a police officer he respect while being in the BO is not a small detail). I think you should somehow not overlook that respect.
So if Bourbon/Amuro is ICPO officer inflitrating the BO, that would give a decent end to the on going "Hey, don't you think Bourbon know too much about Conan/Ai/Agasa/etc. ?"
Well, that would make a lot of people inflitrating the BO, but the "too much people inflitrating the BO" was already reach when it was revealed that FBI *and* CIA were doing it. The Gamma theory doesn't include yet the Mossad, MI5 or DGSE.
Ok, so who is Anokata ?
Well, compared to other character, Anokata is not that much of a new theory. The best suspect would be Yoko Okino. Most of it has already been said - especially by the Texas[dontremeber]girl dug up recently by Chekhov, I won't really insist except two points :
- DC beeing originally targeted to be "few month" long means 10/30 chapter. It's very very short. You can't introcude many complexity in it. The sotry in terms of characters interactions should be quite simple. I don't beleive Yoko Okino was Vermouth's initial prototype (like Chekhov thinks) because Vermouth wasn't planned in the beggining. I think she was introduce to make the story longer.
- And none of the arguments I read about Yoko Okino beeing anokata was the original one that make me point out her in the first place.
This is how I first thought of Yoko Okino : I was wondering what kind of character would be Anokata if he/she was already introduced ? Of course it would be someone you would expect. But DC always has that kind of "moral" issues I can't really describe, but I don't expcet a "very good guy" beeing Anokata. By "very good guy" I mean someone that the reader (and for anime the watcher) would emotionnaly involved with him/her. So I don't except Ran or Agasa, I don't expect Eri neither because she is deeply/emotionnaly involved with Ran.
I don't expect neither a bad guy beeing Anokata, because it wouln't be that much a surprise... "Ho, Anokata is Vodka ? Ok... Well, I waited 20 years for that..."
So I was expected someone like "in between". A neutral character nice, but not too much emotionnaly involved with the main protagonists. And there is not "that much characters" in the manga. Azusa Enomoto would fit the bill for example (at least when I first though about that, she is more and more involed nowadays with Amuro being with her). But she was introduce quite late, first in the anime (1999), named after her voice actress, and then put back in canon story in 2003.
But Yoko Okino is the best candidate in that regard. For example, she is always nice and polite, but Ran never gets close to her despite being several times together. If Ran doesn't worship her as an idol, she does not either dislike her (for beeing a concurrent of Eri for example). They just have a nice and polite relation not more, not less.
So Yoko Okino being a bad woman would be surprising for Ran or Conan, but not heart breaking.
The only one emotionnaly involved with her is... The "dumb Kogoro". I precise the dump kogoro because he always those two faces. The "dumb Kogoro" and the "serious Kogoro". The "dumb Kogoro" can drink too much and be drunk, a case murder happens (or Ran beeing in danger) and the "serious Kogoro" appears. So it's only the involvement of a fool.
That's all for Yoko Okino, every other details has been said elsewhere.
Speaking of Kogoro now. That two faces kogoro... Remember Chap 163/165 ? The scuba diving case. The dumb kogoro was fooling around in sand with women (or appears as he was) while in fact the serious kogoro was looking for Eri's ring in the sand. In general the Eri's cases show us a Kogoro that can do much more that he appears to be doing, and that don't like to gets the credits of his exploits. The exact opposite of the usual dumb Kogoro...
What if THAT Kogoro is the real Kogoro ?
The real Kogoro would be like that : Someone that is quite competent (perhaps a bit slower that Conan, but not espacially that much dumber than him), but that really don't like to get the praise for it. As a police officer, he would have solved the mystery, and then let others find the solution letting them take the praise for it (because that's how he is), letting Megure thinks he's a good for nothing police officer.
That would fit the actions in Eri's related stories, it would also fit Megure's opinion of "old kogoro".
Everything changed when Conan came and "revesed" the roles. Shinichi IS the bragging detective kind ! But he can't brag anymore due to the circonstances. And he's forcing Kogoro to take that role that he don't like (and he's probably uneasy with it).
By the way, if Kogoro always fakes his dumb Kogoro personnality, that means he perfectly knows know Conan is. Chapter 10 "I feel like I've seen you before" "Must be around the time Ran was in grade school" (p 18). Chapter 11 "Wait he's done this before too..." "Whenever I've been stuck... He always gives some kind of hint..." (p 13). Just after that Conan act stupid and he thinks "No way"... But at the end of that story Chapter 12 "But what's really interesting is what he said afterwards... 'I was beaten by a Kid!!' and skeaking of kids nearby..." (he is looking at Conan) "No way..." (this time, it's Ran saying No Way, not Kogoro)
After that, he never ever suspect Conan anymore of anything.
Ok, that must be because it was the start of DC, at that time Gosho didn't know how to position Kogoro yet, and he made him a bit smarter than he is now... Yes, it can be, or it can be that he has always been smart.
With everything in mind, in the context of the whole Gamma Theory, Kogoro being smart, Okino beeing Anokata, and the Dumb Kogoro beeing stupidly fan of Okino would be a hint to the fact that Kogoro might have already been investingating the BO, pin up Okino as highly suspicious but have no proof (as probably Yuusaku) in order to be able to arrest her and her organisation.
Why in the first place did Kogoro stopped being a police officer 10 years ago ?
It hasn't been revealed yet. The movie (ok non canon!) about this provide an explaination about why Kogoro quit police, and why Kogoro and Eri don't live together, but it hasn't been confirmed.The conclusion of the movie was that Ran beeing in the same situation clearly understood why kogoro has shoot Eri that time, so Eri no beeing stupide would have clearly understood it the same way, and so it's NOT the reason why they don't live together. Back to square one, that movie like every other movie doesn't make the main story avance even a bit.
What if the reason why Kogoro stopped being a police officer 10 years ago was to start investigating the BO ? Perhaps with the help of Yuusaku, or being manipulated by Yuusaku.
The relation between Yuusaku and Kogoro seems (Yuusaku's cold case) to be very cold, at least from Kogoro's side. But keep in mind that it's EXACTLY the kind of cold and arogant speak he reserve to Eri. And we all know how he really feels about Eri. So Yuusaku and Kogoro may be like brothers.
Speaking of brothers, if Agasa is Watson's Yuusaku-Holmes, that would make Kogoro-as-a-brother Yuusaku's Mycroft, the one who is smarter that Holmes but lazier and thus seems dumber.
I must confess that the Kogoro not beeing what it look doesn't really fit with recent chapters like 855. Anyway, some points in the Gamma theory may be true without the others. (For example only Gin=Yuusaku, or Bourbon=ICPO/Interpol)
But there are two people that really seems to be way above Conan/Shinichi in term of deduction. Yuusaku and Gin. they both seems to have 2 or 3 plans ahead of Conan. They are both scary guys.
When Yuusaku was first introduced, it was still like it was Conan versus BO, and Yuusaku is a busy man, so as BO is Conan's problem, it made sense at that time that Yuusaku would let him solve the mystery alone.

Well, it doesn't make any sense if the drug would have killed him, but if Yuusaku/Gin knew the drug would have only shrunk him, he's clearly the kind of father that would do it to make a new powerfull pawn enter the checkboard : Conan.
Well, how would he know ? Shiho wouldn't even have predicted it. Well, what if the drug wasn't made by Shiho but by Elena and/or Atsuhi Miyano.
Somehting happened to the Miyanos some years ago. We don't know what, they are assumed dead but we don't even know it exactly. What if they went in contact with Yuusaku, something like 10 years ago (that can be another time). For example, they tryed to escape the organisation by leaving a crypted message somewhere that only Yuusaku was able to decrypt and understand.

I hope it's not unreadable, English isn't my native's language and I'm not used to write such long text in English.
