At first I'd thought the story was implausible. After all, interns such as Miren don't get to work on stories of international importance. However, with input from veteran character actor Jose Corinado as experienced reporter Eduardo, things seemed much more stable. Miren threw herself into the story of the disappearance of the little girl and, while producing some good copy and a couple of scoops, she failed the rule of journalists not to get personally involved when she tried to solve the case.
There's one very minor clue in the first episode as to who the abductor might be, but it would take dogged investigating to find out the perp, something a viewer couldn't do. So the revelation in episode four of the back story of the kidnappers was something that couldn't have been guessed.
There were plenty of red herrings too, some involving Miren's shocking experiences prior to the series' start and which also explained how she knew Inspector Millán.
All was revealed, including the provenance of the title of the series which had puzzled me - no snow features at all. But, as British Rail once said in a different context, I was looking for the "wrong type of snow".
I watched the lot over a twenty four hour period and I recommend it.
