Stars of BBC One drama Sherlock appear to have taken a trip through time as actors Benedict Cumberbatch and Martin Freeman pose in period costume for a forthcoming one-off special.

　　BBC探案劇《神探夏洛克》日前公布了一張2015年圣誕特別版的造型照，兩位主演本尼迪克特·康伯巴奇和馬丁·弗里曼全部現身，而兩人的裝扮似乎暗示該集劇情將“穿越”回19世紀。

　　Although the two stars are pictured next to each other, the image appears to have been assembled from two separate shots of the stars as a montage.

　　照片里的兩人雖然并排而站，但似乎能看出來這張合照是由兩張單獨的照片合成的。

　　The image which was posted online actually has a chunk of Cumberbatch's shoulder missing.

　　因為照片上的康伯巴奇肩膀處好像缺了一塊兒。

　　The BBC has previously confirmed the programme will make a return with a special followed by three more films.

　　此前BBC曾確認該劇將以一集特別版回歸，之后將再拍三集。

　　Show producer Sue Vertue, who is married to writer Steve Moffat, suggested that the wheels are now in motion for the consulting detective's return by tweeting an image of its stars Cumberbatch (who plays Sherlock Holmes) and Freeman (John Watson).

　　制片人蘇·維特之前在推特上發了一張卷福和花生的合照，暗示著該劇即將回歸。

　　She accompanied the picture with a caption which read: '#221back #Sherlock #notkidding'

　　她還給圖片加了標簽#221回歸#神探夏洛克#不是開玩笑。

　　Vertue also posted an image of a script for the programme, written by Moffat and Mark Gatiss, and said there had been a read-through earlier in the day.

　　維特另外還上傳了一張莫法特和馬克·加蒂斯編寫的劇本的照片，并稱已在當天早些時候讀完了該劇本。

　　She wrote: 'This is what we've been doing today.'

　　她寫道：“這是我們今天一直在忙的事情。”

　　No date has been given for the film to be finished but the BBC has previously said filming will begin in January.

　　具體的完成日期并未給出，不過BBC之前曾表示拍攝會在明年1月份開始。

　　And there is no explanation why the pair are in period costume for the programme which has updated Arthur Conan Doyle's characters to the present day.

　　另外官方至今未對兩人照片中極具19世紀風格的裝扮給出任何解釋。

　　The third series of Sherlock finished earlier this year but fans were warned they probably face a lengthy wait due to the commitments of its in-demand stars.

　　《神探夏洛克》第三季于今年年初結束，由于該劇主創們安排緊湊，所以粉絲們要等候很長一段時間才能迎來下一季。

　　The series climaxed with a flood of images of villain Moriarty - played by Andrew Scott - repeating 'did you miss me?'.

　　第三季結尾出現的一系列大反派莫里亞蒂的畫面以及不斷重復的“想我了么？”的聲音將劇情推向高潮。

　　Fans have been left in suspense as he was thought to have died.

　　因為大家都以為莫里亞蒂已經死了，所以這給粉絲們留了個很大的懸念。
