Series with the "good guys" being unsocial and/or with special needs have recently become popular, with the Scandinavian The Bridge as evidently the most renown. Here, in Chasing Shadows, the roles are reversed: the male lead DS Sean Stone (remarkably performed by Reece Shearsmith, whom I have not knowingly seen/noticed before) is the one who has serious communication issues, and the others, including Ruth Hattersley (nicely depicted by Alex Kingston) have to deal with and tolerate him for the sake of solving serious crimes.
Despite the fact that being rude to women is not pleasant to follow and my hesitations whether the British police can afford such a non-team player, the plots have been smoothly designed, the leading characters are not always right, the endings have nice twists, and the concrete person at fault is not revealed too soon. I would like to see more with these characters; the Episode 4 somehow promised a sequel, but no more episodes until now (1-4 were aired in September 2014).
