I'm loving, really loving, the idea of this story, The 21 Steps by Charles Cumming, and how you can use the internet to visualise the plot. The story is told caption-form above aerial shots of London. But is it just me or did it make anyone else feel sick? I haven't managed to get to the end yet. It's not the content, it's the sensation - like reading a book in the car. I could never do that either.
