Really enjoyed the first 10 episodes albeit annoyed with the BBC that originally their website suggested episode 10 was the series finale. Glad that they have now clarified on the website " When will the remaining episodes of I Know Who You Are be shown? I Know Who You Are will return to BBC Four later this year. The programme was originally produced as two seasons, however, its Spanish broadcaster subsequently decided to show both together as one long season. BBC Four is showing the final six episodes as series two. We'll update this FAQ when we have more information." http://www.bbc.co.uk/faqs/i-know-who-you-are
