All roads lead to Rome, so it was inevitable James would end up in Italy's magnificent capital. But it's not just Romans and ruins, James also goes on a bus, meets another version of himself, and looks at something too small to see.

Size matters, as James visits the vast marble quarries of Carrara and the massive Genoa port. Then it's to the elusive, as James searches for a semblance of peace in the face of killer robots, and a decent cup of tea in Turin.

In Milan, James submits to a wardrobe update, tries his hand at some exquisite craftsmanship - and bids goodbye to an old friend. Next stop: Venice, by land, air, and lagoon, while in the Dolomites James finds the darker side of Christmas.
