This is another of John Ogdon's (1937-1989) opera arrangements from a fantasy novel. This time, he has focused on the famous queer Gothic novella "Carmilla" by Joseph Sheridan Le Fanu. This scene here directs one of the most famous parts of the novel, the supposed dream encounter that Laura has with a black panther like creature in her bedroom only to look for it and see the figure of young women by her bed instead. The stage directions to the right of the page are precise and animated, and tell us what Ogdon's vision for the scene would have been.
As far as I know, Carmilla nor his operatic account of "The King of Alsander" were ever performed.
