We can't wait to see Sherlock and Watson in the one-off episode this Christmas-ish, but until that time check out these other 10 exciting details below:
我們迫不及待地想要看到夏洛克和華生在這一集聖誕特別篇中的表現了，但是首先讓我們一起來看看以下10條激動人心的細節（劇透？！）吧：
1.We know who is returning for season four
So far, the confirmed cast includes leads Benedict Cumberbatch and Martin Freeman and regulars Amanda Abbington as Mary Watson, Louise Brealey as Molly Hooper and Jonathan Aris as Anderson.
1. 我們知道在第四季中誰將回歸
到現在確認出演的演員陣容包括主演本尼迪克特·康伯巴奇和馬丁·弗裡曼以及常規成員阿曼達·艾賓頓（飾演瑪麗·沃特森）、路易斯·布雷利（飾演茉莉·胡佩爾）和喬納森·阿里斯（飾演安德森）。
2. Season four will be darker
Moffat spoke with Entertainment Weekly saying the production team wants to take the "Sherlock" series somewhere its never been in previous seasons.
2. 第四季將會更加黑暗
莫法特告訴《娛樂周刊》的記者，製作團隊希望將《神探夏洛克》系列變得和以往幾季完全不同。
During the "Sherlock" panel at SDCC '15 Moffat talked more about the darker tone of season four saying.
關於第四季更黑暗的基調，在2015聖地牙哥動漫展舉辦的《神探夏洛克》座談會上，莫法特談到了更多。
"We've got a clear idea of what we're going to do and it's going to be a clear shift in tone," Moffat said.
「我們對於劇情的走向有著非常明確的構想，基調將會有明顯的轉變。」莫法特說道。
3. Irene Adler may return!
iDigital Times reports that Irene (Lara Pulver) may return to "Sherlock" for season four. If you don't remember Irene she was a love interest to Sherlock and much more than that during the early season.
3. 艾琳·艾德勒可能會回歸！
據《數字時代》報導，艾琳（拉臘·普爾弗飾）可能會在《神探夏洛克》第四季中回歸。如果你不記得艾琳是誰（讓我們來科普一下劇情），夏洛克對她很感興趣（戀愛傾向的那種），且在前幾季中，她還有其他不凡的表現。
4. Janine Returns!
Another love interest of Sherlock's and Mary's close friend, Janine will return for the upcoming season. According to Moffat she will definitely be back and her and Sherlock will be friends.
4. 亞尼內將會回歸！
另一個夏洛克的愛慕者——也是瑪麗的好友亞尼內——將會在接下來的劇集中回歸。據莫法特說，她確認會回歸而且和夏洛克會成為朋友。
5. Moriarty is not Alive!
Moffat said early on that Moriarty is indeed dead and not coming back. The writer said "He shot himself in the face. What more do you want?"
5. 莫裡亞蒂死翹翹了！
早些時候莫法特說過，莫裡亞蒂已經死得透透的而且不會回歸了。這名編劇說道：「他都飲彈自盡了你還指望些啥？」（魔法特我們能相信你嗎？！！！）
6. Tom Hiddleston may join the cast
The "Avengers" villain is said to be joining the cast of "Sherlock" for season four. Online speculations have said that he will join as the third Holmes brother.
6. 湯姆·希德勒斯頓可能會加入演員陣容
據說《復仇者聯盟》中的反派可能會加入《神探夏洛克》第四季演出。網絡上有猜測說他將會以福爾摩斯第三個兄弟的身份出現。（這究竟是放大招還是空穴來風？！！！魔法特你粗來解釋一下啊！！！）
7. Future seasons are already planned!
Moffat told the Guardian that He and Mark already planned ahead for more seasons saying, "Rather excitingly, Mark and I, for no particular reason, we just got out of the rain… and we just started plotting out what we could do in the future." He also added that there was no plan for a movie as each episode is a feature length itself.
7. 未來幾季已在醞釀中！
莫法特告訴衛報記者，他和馬克已經在計劃未來的幾季了：「更激動人心的是，如無意外，馬克和我已經有譜了……我們已經在心中規劃好了未來該做點什麼。」他還補充道他們並沒有拍攝電影的計劃，因為每一集的長度已經達到了電影長片的長度了。
8. Will Mary Die?
FashionNStyle reports that season four may see the end of Watson's wife, Mary Morstan. While anything is possible we don't think the creators or producers would get rid of a dynamic female character such as Mary, well not anytime soon anyway. What's more, Martin Freeman has revealed that the show will follow the same path.
8. 瑪麗會死嗎？
據FashionNStyle報導在第四季中華生的妻子瑪麗·莫斯坦可能會死去。雖然萬事皆有可能，但是我們覺得創作者和製片人應該不會捨棄像瑪麗一樣充滿活力的女性角色，至少不會很快。此外，馬丁·弗裡曼透露第四季將會延續之前的劇情。
9. Steven Moffat reveals season fours theme
"The first series was all about the beginning of their friendship. Second about the formative stages, the love and fear and loss and all that. The third was good days, me and my pal and my pal's wife." Moffat told Entertainment Weekly.
9. 史蒂芬·莫法特透露了第四季的主題
「第一季主要是關於他們的友情是如何開始的。第二季是關於成型階段，愛、恐懼與失去等等。第三季是關於好日子，「我和我的朋友及朋友的妻子」（傳說中的三人行？被PIA~）。」莫發特告訴《娛樂周刊》的記者。
10. Production will begin in the Spring
Chatting with Digital Spy after the Bafta TV awards, show runner Steven Moffat confirmed that series four is planned to start filming in spring 2016.
10. 拍攝將於春季開始
英國電視學術獎頒獎後，電視劇製作人史蒂芬·莫法特和《數字間諜》閒聊中確認第四季將於2016年春季開始拍攝。
