Do you like Agatha Christie's Poirot? It's a British mystery drama TV series.
I've never heard of it. Is it new?
It aired on ITV from January 8 1989 to November 13, 2013.
Wow, crazy I spend a lot of time in the UK. Mainly Scotland I have never seen it. What was it about?
Each episode was adapted from one of Agatha Christie's short stories or novels that featured Poirot. Poirot is both the main detective and also the protagonist.
Was each season the typical British 6 episodes? 
There were 13 seasons and 70 episodes total, so that sounds about right.
