I've listened to the Archers on and off over the years. (No car radio now 
). Gave up for a bit as I found the new Pip very grating.
Now Dr Lock has turned up. Can I ask - Is he the same Richard Lock who used to live with Usha and had an affair with Shula (while she was with Alistair)? If so I find it weird that Shula seemed to pleased to see him!
