I thoroughly echo Kevin's comments about Dan Carlin. Also knew little about the history of First World War, even though my late father was fascinated by it, and our house was full of books about it. Dan Carlin drew a picture of events that horrified and fascinated me.

In the past I have listened to Frank Delaney a lot on BBC Radio, where he presented programmes called "Bookshelf" and "Word of Mouth", both absolutely excellent in my opinion. I shall follow your recommendation and try his podcast as well.

Thanks for such an interesting show.
