Your summer like ours may have been enlivened by grippy absurd bizarre ultra-Spanish psycho-melodrama I Know Who You Are. Hey it’s on BBC4 so it’s educational as well right. After ten episodes of twisty amnesiac drama things came to an abrupt end. Very abrupt as it turns out the final episode was not the end at all but only two-thirds of the way through the series. Well it is back back back baby this week so we can see what has happened to Ana, Alicia et al. so if it’s slipped your attention (we had the Guardian listings to thank for the alert) then get on the iplayer right now. Best not to start two-thirds of the way through but I think the whole glorious shebang is available. There are many things to love about this series, but the penchant for the entire Spanish legal system to go to work in Zara’s best smart casual wear is both easy on the eye and mystifying.
