As doctors try to establish whether it definitely was a heart attack or another underlying condition, Pam's daughter Meg talks about how her bond with her mum has strengthened over the years and how she helped her mum when she and Meg's dad decided to get divorced. Ten-year-old Cora is rushed to St George's after being thrown from a horse into the low hanging branches of a tree.
