I came in on the end credits and the memoriam photo of Lucy Booth - same age as my own daughter - so I had to find out who she was.
I watched the introductions at the beginning on iPlayer and saw that there was a mother and daughter duo featuring a Lucy, but she didn't look anything like the picture they posted at the end.
Today I Googled it (there are loads of links) and discovered the sad story about Lucy battling breast cancer and, due to the kind hearted production bosses and the BBC, being able to see a copy the programme shortly before she died.
RIP Lucy .. sadly you won't be the last young lady to lose your battle in this way.
