I can highly recommend Unforgotten, a BBC police drama. First 2 seasons are on Netflix, I just finished the latest season on BBC 1 and enjoyed it so much I binged watched the 1st 2 seasons again. Its always a cold case, hence the title. Keeps you guessing til the end and it doesnt shy away from what is at times pretty harrowing subject matter {could be triggery}
