Belgravia by Julian Fellowes an entertaining romance and look at a changing exclusive society

It’s a kind of London counterpart to rural Downton, set in fashionable Belgravia in the 1840s, with a similar cast of powerful older women, intriguing servants below-stairs, and beautiful young women, challenging the boundaries imposed on them by a rigidly hierarchical society.
Here, as in Downton, Fellowes displays his extraordinary gift for bringing the past, its customs and domestic detail, to life for the contemporary reader.
