To ask MN sleuths to help me find this obscure drama!

[deltablue]

Ok, it's def pre-pandemic so around 2018/9 I think. Spanish miniseries- I think there were 8 and a further 2 were planned for a full year later! Talk about suspense.
Anyway, man and wife, both successful architects running their own practice/s. Stupendous house (of course) prob in Madrid?
Daughter goes missing (she's late teens) and for some reason Dad becomes the suspect .
Utterly gripping, and I cannot for the life of me find it anywhere- nor the final episodes , and it's driving me mad!
Dad - tall, dark, handsome in a broody Spanish way- prob late forties. Wife striking and I think not stick thin, again mid to late forties.
Can anyone help?

I don't think they ever showed the end. I remember that too.

No idea but am placemarking as it sounds great!

I remember this! They did show the end later on but apparently they had only paid for about 75% of the series at first. Will try to remember the name.

El Embarcadero / the Pier?
The main character was an architect in that but I never finished watching!

Here we go, they did show it.

I remember liking the start but giving up because it was very silly.

ShinyMe- that's it!! I know Who You Are! I can now sleep again! And will try to watch it again! Thank you

I remember watching 2 series of this! Were there any more? I think it was the wife’s niece that went missing and the main guy had potentially lost his memory in a car crash.
