I've seen John some time ago presenting questions of a religious/philosophical nature; don't forget, he was a journalist in the first place, which is what he was doing when he was kidnapped.
I have just read their book. Not having read a book for years I found it a fascinating read. Coming from the North East I do not remember what the local coverage of John's plight was like. I would like to have met both of them, hope they are both well & happy.
