We have an early Christmas present for fans of Sherlock in the form of two clips from the first episode of season 2 "A Scandal in Belgravia."

As we have previously mentioned this episode is based on the Sherlock Holmes short story "A Scandal in Bohemia," where we will be introduced to "the woman" Irene Adler (Lara Pulver). Whilst the clips don't feature Adler, nor do they reveal how Sherlock (Benedict Cumberbatch) and Watson (Martin Freeman) escaped their predicament at the hands of Moriarty (Andrew Scott), they do set up the new season.

The first clip has DI Lestrade (Rupert Graves) warning a colleague about Sherlock's unusual and potentially infuriating methods. These unusual crime solving techniques get revealed to this detective as Sherlock hasn't even travelled to the crime scenes, sending Watson alone with a laptop. This means that Sherlock doesn't even need to leave 221b Baker Street but can still investigate thanks to Wi-Fi and a webcam. Sherlock seems to have a new system to judge whether a case is worthy of his physical presence and this case is a '6' and Sherlock doesn't believe there is any point in his leaving the flat for "anything less than a 7." This clip also showcases how unobservant Sherlock can be as he hadn't even realised that Watson was in Dublin.

Of course Sherlock is also incredibly perceptive and this is demonstrated in the second clip where he not only gathers significant information about the person in front of him with a glance, but also about the absent and extremely important employer. Sherlock has some distinctive interpersonal skills that are on display in both clips; with those he is in familiar with like Watson and with people he has never met before.

Fans of Benedict Cumberbatch will also be happy with his bed sheet attire in the first clip; will he do for bed fashion what he has managed to do with long coat and scarf combos? Cumberbatch spoke to the BBC about the costume on the show saying:

"The coat was Ray Holman's, the costume designer's idea. Sherlock's suits have a clean, linear, perfunctory beauty about them, there's nothing showy or flamboyant. They're very well cut, functional but still very stylish and I think that sums up Sherlock perfectly."
