I've lost my TV programme - help please

I've watched both Cra and Blue Lights, but might be worth another look. Thanks.

Crá on iPlayer is a good Irish drama.

If you enjoy crime stories based in Ireland, why not try the excellent 'Blue Lights' based in Belfast. It just won a BAFTA.

I was hoping it was free with Prime, but doesn't appear to be!

I was about to suggest The Vanishings as it’s very good.

I don’t think I’ve come across Borderline so I’ll seek it out.

I found it - more by luck than judgement!

It's call Borderline on Prime Video.

Thank you kindly for your help.

The show is a dramatization of the real-life cases, and while the specific details may differ, the core theme of missing women and a potential serial killer is present,
