Now there's a face we haven't seen in a while (unless you watch Crimecall, obviously). Grainne Seoige is back on our screens tonight for the first episode of a brand new series which tells the tales of some truly extraordinary Irish journeys. She'll be retracing the steps of of a Unionist philosopher by the name of Thomas Carlyle, and his old Nationalist politician pal Charles Gavan Duffy. Plus, there's even time to fit in a bit of a history lesson, by looking at the Great Famine through the eyes of the ruling elite.
