Whodunnit

We've spent the last 8 weeks watching Broadchurch on itv.
It's actually been really good -unlike this blip- just a bit slow at times with not a lot happening in the middle of an episode and then a a cliffhanger at the end.
Who'd have thought the killer would be........marjorie.

Broadchurch will return...? Are they going to kill everyone off by the end?
