This week we say farewell to a few series – Lynley, Grantchester and Patience. We also say hello to one big, new series – Under Salt Marsh, starring Kelly Reilly and Rafe Spall – which looks really good. It’s also worth mentioning that BBC Two has (inexplicably) taken Mystery Road: Origins out of primetime and out it into a later slot on Thursday. Enjoy!
