This is a still from the second episode of Sherlock. The show is about Sherlock Holmes, and preserves the characterization of original. The plots are modernized and  loosely based on the original books. The show aired its first season on the BBC in 2010 and its second in 2012.
On the episode in question, very little of the show was based on the original book, and nothing about the characters' ethnicity was pulled from this. The still shows Soo Lin Yao, a one time character on the show. She was involved in a gang, which is actually an ancient Chinese crime syndicate, and was a drug mule. However, once she comes to England she somehow magically knows how to perform complex tea ceremonies and appraise antiques and gets a job in a museum. She is now obsessed with the teapots and acts like they are alive. She also quotes ancient scholars. After being shown for a little in the beginning, she disappears. When she returns again she helps Sherlock solve his mystery, and then gets shot in the head and dies.
