One of these years, Javier Marías will probably win the Nobel Prize in Literature. If and when that honour happens, critics may well discuss the Spanish writer’s fiction, in all its “intensity, complexity and power to convince”, in much the same terms as he applies to one of his favourite works of art.

So, if you’re reading this you probably trudged all the weary way to the very end of I Know Who You Are. Or you didn’t but still want to find out what the hell happened. After 20-plus hours of twisting, turning, overblown drama, long-service medals are in order for all who flopped over the line. We are probably all feeling as drained and battered as half the cast: black-and-blue Santi Mur, anaemic Ana, slapped-up Pol, smashed-to-smithereens Heredia.

Here we go again then. The “first series”, as the BBC are calling it after the fact, of I Know Who You Are slammed the brakes on and juddered to a bewildering halt back in the middle of August. Almost everyone who’d sat through the plot dodgems of those 10 episodes will have had the same reaction: eh?

Pere Portabella’s remarkable Vampir Cuadecuc is almost impossible to classify. It may have been filmed on the set of Jesús Franco's 1970 Hammer horror film El Conde Dracula – with the obviously enthusiastic participation of a cast led by Christopher Lee – but it certainly isn’t a "making-of" film.

Albert Hammond might not be a household name but he's still, undeniably, one of the world's greatest living songwriters. His songs have sold 360 million copies, ranging from Starship's soft-rock classic "Nothing's Gonna Stop Us Now" to Julio Iglesias' "To All the Girls I've Loved Before".

The first thing to say is that this wasn’t the actual end. BBC Four scheduled I Know Who You Are to run two episodes a night over five Saturdays. The innocent punter might have assumed that after 10 x 70 minutes of the Spanish import, we’d arrive at some sort of terminus. With only a few minutes still to run, who wasn’t thinking, crikey, still quite a tick list of bows to tie up?

The sixth in a series of crime novels that began in 2011 with Or the Bull Kills You and which introduced readers to Chief Inspector Max Cámara, Fatal Sunset opens with our anarchistic hero summoned to see Rita Hernández, newly installed Commissioner of Valencia’s Policia Nacional.

Clonter Opera is a finishing school for young opera performers, with its own well appointed theatre and professional administration and artistic direction, based on a farm in Cheshire near Jodrell Bank. It’s seen a succession of promising young post-conservatoire singers come to perform in fully staged productions for many years, and is also (from an audience point of view) the only countryside summer opera venue of any substance in the north of England.

All’s fair in love and law in I Know Who You Are. BBC Four’s latest Euro-import hails from Spain and, as per the channel’s practice, is coming at you in intense double doses, two 70-minute episodes every Saturday night.
