Jane Wunderly has infiltrated a secret cult. She's mainly on her own though her fiance, Redvers, is also on the island. This is the Golden Dawn, based on a cult that actually existed. And involved in that cult? W. B. Yeats who makes an appearance in this book. Not sure if it's actually successful though.
The mystery deepens when one of the initiates is killed but nobody's really sure how it was done. Add in a rival cult made up of former members and the suspect pool deepens.
