BBC Four is now showing the television series based on my book again: http://www.bbc.co.uk/programmes/b01r6z2d
And it will be on iPlayer for the next week or so. The one good thing about BBC Four's relatively modest commissioning budget means they tend to repeat their original programming quite often, so this is our third outing on TV.
There probably won't be a second television series in this specific format, much as I'd love to work with the same team again on such an interesting and appealing topic. However I am starting a research project in the autumn on the origins of certain holy places and practices, which should eventually result in another book. Will post more on here in due course.
