It feels like everything is adapted from a book these days - West End plays like War Horse, Woman in Black or Matilda, films like...well, War Horse and Woman in Black, but also Salmon Fishing in the Yemen, Hunger Games, Sherlock Holmes; tv drama such as - there's a theme here - Sherlock Holmes, Birdsong, Vera (the detective from the novels by Ann Cleeves). And if this isn't enough to fuel your reading habit, you can get a whole new booklist from the characters themselves.

I only managed to catch a couple of episodes of Mad Men, the American tv drama set around an advertising agency in the 1950s, but I read of its success. And I was intrigued by the re-release of a book first published in 1958 called The Best of Everything by Rona Jaffe which was featured in the programme. Apparently the storyline had one of the male leads sitting in bed, reading the book as he sought to gain an insight into the lives and motivations of his female workforce. The book has subsequently become a bestseller and other titles popular in the period have been featured!

Or what about The Best Exotic Marigold Hotel? This feel-good spectacle of vibrant colours, beautiful scenery and fine actors was an adaptation of These Foolish Things, a book by Deborah Moggach. During the film, one of the characters is reading - the book is Tulip Fever, also by Deborah Moggach. I stopped myself from nudging my companion to point out this fascinating fact. (You won't be surprised to learn that I also revel in spotting continuity errors in films!)
