Errol - Mark was avoiding the horse that Caroline was riding, yes. He went into a tree while on his mobile to Shula and we heard the whole thing on air. Caroline was either in a coma for a while and emotionally traumatised, or just emotionally traumatised, and in the end she called off the wedding as she realised it wasn't what she wanted. Not her first long-term relationship to go up in smoke, either - she had been previously been living with a doctor whose name IIRC was Matthew Thorogood.
I think he was the one who sold the practice to Richard Locke, who lived with Usha and had an affair with Shula. And before that there was some army chap who was in Berlin.
Curlew - yes, I agree. I've resisted that way of thinking for umpteen years but just at the moment TA is about as bad as I can ever remember. I wonder how things will change when the new Editor takes charge.
