End Notes

 Harriot Freke :  a character in Mrs Edgeworth's Belinda who wears men's clothes and who challenges the unhappily married Lady Delacour to a duel.

 "from the time before which the mind of man runneth naught to the contrary" : an English legal explication for time immemorial otherwise known as prior to 1189.  A hint at the dating of the Malfoy family's arrival in Dorset.

 "Look on my face, ye mighty, and despair."  "My name is Ozymandias, King of kings/Look on my face, ye mighty, and despair".  Shelley: Ozymandias.

 "Eight years it will be come Lammastide":  see Romeo and Juliet, Act 1 Scene III for why Narcissa might reasonably think she is being sent up.  Lammas is also the feast of Lughnasa, and is treated as being 1 August for most practical purposes.

 "Positively Danversesque": Mrs Danvers is the housekeeper in Daphne du Maurier's Rebecca whose obsessive affection for Rebecca causes so many problems for the second Mrs de Winter.

 "DeVries Caught Out With The Berkeley Hunt" : one can only assume that the sub-editor of the Prophet responsible for that one was relying on his superiors being unfamiliar with Cockney rhyming slang.  The Berkeley Hunt, in Gloucestershire, are also famous for wearing yellow coats rather than the traditional pink.

 "with Porton Down just up the road":  Porton Down Chemical and Biological Research Establishment is located just south of Salisbury in Wiltshire, the neighbouring county to Dorset, and probably less than thirty miles from Malfoy Intrinsica. Set up in 1916, the famously secret British defence laboratory has been the focus of sinister rumours practically ever since.

 The Quaker: it seems Sir Rufus has had Somerville & Ross's Irish RM in mind when naming his horse.
