I'm on the fourth season and I can't tell if Vera is bipolar or an underestimated caring person or both. I really love this show but I do miss Billy a lot. The background is beautiful and just when you think you have the mystery solved it has twists. It took me a long time to finally get into this show but now I'm hooked. I can't wait to get to the last season and see what happens. These writers are amazing and the actors are tremendous but I don't expect anything less from the British. I love all the scenic ones. I'm not big on the ones in the bigger cities but I do love the ones with beautiful scenery.
