This cracking crime show about cops (and exes) who must join forces again after many years deserves special awards for services to will-they-won’t-they TV. Don’t let it get away!

The One That Got Away is a rare double delight – something not just better than you were expecting, but better than it needs to be. It is the English-language remake of the Welsh drama Cleddau, by Catherine Tregenna, in which two detectives with a shared past are forced into partnership once more when a new crime has echoes of a historical murder they worked on together. Is it a copycat, or did they put away the wrong man? Could there be another explanation? And when are the two detectives with a shared past going to have sex?

So far, so classic premise. If, as I do, you believe it is a classic for a reason, you will already be happy to spend six hours in TOTGA’s warm embrace. If you do not, then you will miss a smartly plotted thriller, set in a Cambrian seaside town, that captures the warm intimacy and chilly bleakness of small-town life. You will also miss a drama that provides an astute portrait of complicated adults with complicated relationships that holds the attention no less than the twisty narrative.
