A member of a forum I frequent posted a link today, to a forthcoming novel titled The Perils and Dangers of this Night. The author is credited as one Stephen Gregory.
Now for anyone familiar with the three, existing Gregory novels; The Cormorant, The Woodwitch, and The Blood of Angels, this is very exciting news indeed. His last book, Blood of Angels, was published way back in 1994. Is the wait finally over?

I cannot find any confirmation, as of yet, that this forthcoming title is indeed written by the same man. I emailed him some years ago to ask if he had anything in the pipeline and he replied with a very definite no. Not that he was rude or short in any way, quite the reverse. He was delighted and touched that I should contact him.
I've emailed him again, in light of this news, to ask if this new novel is indeed his own. If and when he gets back with an answer, I'll post an update here.
