Margaret Oliphant (1828 – 1897) was a prolific and very popular author in her day, and M.R. James describes ‘The Open Door’ as one of only two ‘… really good ghost stories I know in the language wherein the elements of beauty and pity dominate terror.’

‘Brentwood house’ in the story was mostly likely inspired by this house, where Oliphant stayed on a number of occasions as the guest of her friend William Blackwood III, publisher of Blackwood’s Edinburgh Magazine in which this story was first published. The house, now a school, features a picturesque castle ruin in the grounds, complete with open doorways leading to nowhere.

While the house in the story is almost certainly based on Colinton House, the adjoining village of Brentwood is more likely to be based on the village of Lasswade, where Oliphant grew up. Like Lasswade, the village in the story is described as being a centre for paper-making. This article by Rosemary Mitchell also provides some fascinating analysis of the religious symbolism in the story.

This essay by Laura Witz, subtitled ‘Subtle subversions of Victorian gender conventions’, argues that Oliphant was a feminist whose fiction struggled against the restrictive gender norms of the time. Not that you see much of that in ‘The Open Door’, sadly.

This website contains not only a bibliography of Oliphant, but also plot synopsis for all her published fiction. The ‘Stories of the Seen and the Unseen‘ section will be of particular interest to fans of the ghost story.

A ‘bogle’ is a uniquely Scottish ghost of folkloric creature, one which the stable-master Jarvis is particularly keen to insist he is not afraid of in this story!

The doctor is keen to attribute the multiple ghostly sightings as an example of mass hysteria. The wikipedia page on mass hysteria  contains some fascinating examples of this, from mewing nuns in the middle ages to modern forms of viral mass hysteria reportedly spread by the internet.
