I hope you manage to find a copy, my husband found mine from a second-hand book shop online because being published in 1962, it is now sadly out of print. I have just googled the author's name and imagine my surprise to discover that Rosalind Erskine, whom I'd always believed to be a 15 year old giri, was in fact a man!!
I quote from the internet...............
"In 1962, Rosalind Erskine's novel The Passion Flower Hotel caused a sensation and became a best seller. It tells the story of Bryant House, an exclusive private girls' school whose sixth-formers find themselves unable to meet boys or learn about sex. Over at Longcombe school for boys, the equivalent problem exists. The solution is still shocking: the girls set up a brothel in the school basement, with a menu of categories and prices.
At the time of the book's publication, it was virtually impossible for pupils in private schooling to mix sexes, unless you counted events such as the annual opera, when schools teamed up to provide the right gender balance. The St Trinian's films had already tackled the subject of schoolgirl sexuality, and Bryant House's Passion Flowers riotously smashed down the walls. The book spawned two inferior sequels, a terrible German-made film starring Nastassja Kinski, and a hit West End musical with a Bond-like score written by John Barry.
The big selling point was that the author, 15-year-old Rosalind Erskine, was supposedly being educated at just such a school. Misinformation abounded about her – did she even exist? The answer is of course she didn't!. Rosalind was Roger Erskine Longrigg, the creative director of an advertising agency, who recognised that the time had come for a smartly written erotic comic novel. The book is a joyful and oddly innocent romp, but would probably have risked opprobrium had it been published under a male name."
I'm gobbed!!!
