How to behave like a duke

As Downton Abbey returns to our screens this weekend, those who want an insider guide to how the other half live can check out a new book.

Deportment for Dukes and Tips for Toffs is the original deportment guide for aristocracy, and has been reprinted by British Library Publishing.

Tips include: Never point your gun at your fellow sportsmen without previously consulting the wishes of your host; avoid the vulgar and objectionable habit of conversing with your fellow travellers; and be on your guard when asked a civil question. If you cannot answer rudely then do not reply at all.
