RadioTimes.com<\/a> can exclusively reveal a first look-clip from the episode, which sees Okonedo\u2019s exasperated detective Kat bicker with characters played by Shearsmith and Pemberton.<\/p>\n\u201cWhere\u2019s it gone?\u201d she asks Pemberton at the beginning of the clip, and when he simply responds with \u201cWhat?\u201d she clarifies: \u201cThe entire investigation.\u201d<\/p>\n
\u201cI\u2019ve still got the notes, I just didn\u2019t think it was good to put it up on the wall,\u201d he answers, much to Cat\u2019s dismay.<\/p>\n
\u201cYou have no right to tell me how to run this case, no right at all \u2013 do you hear me?,\u201d she says. \u201cI was this close to making a breakthrough.\u201d<\/p>
At this point Shearsmith\u2019s character Barney enters the room and things only get more tense from there. The clip ends with Kat yelling: \u201cJust shut up Barney!\u201d<\/p>\n
We\u2019ll have to wait and see how this all fits into the episode on Wednesday night\u2026<\/p>\n
