The Mysteries of Verbena House; or, Miss Bellasis Birched for Thieving by Etonensis is a Victorian spanking novel in two volumes. Volume I was published in 1881 and Volume II in 1882, which included both volumes in one book.
The pen name Etonensis refers to a person who has attended Eton College, a British school famous for their use of the birch. The novel is usually attributed to two authors: Volume I is attributed to George Augustus Henry Sala, a journalist. Volume II is credited to James Campbell Reddie, an author and collector of erotica.
The Mysteries of Verbena House was illustrated with “4 coloured lithographs, obscene and of vile execution” by an anonymous artist, see below.
