Charles Gordon Waugh was born in Philadelphia, PA, in 1943. He has published over 261 books, most of which are SF, fantasy, or horror anthologies and he has taught at Syracuse University, Ithaca College, Kent State University, and the University of Maine at Augusta.
Waugh is known primarily as a co-editor (with Isaac Asimov and Martin H. Greenberg) of the “Mammoth Book” series of genre anthologies.
Many science fiction anthologies start with an explanation that the definition of science fiction is rather blurry. This book didn't, but maybe it should have. It has helped me see that in my personal definition of science fiction, I like there to be some actual science. It doesn't even have to be tech!
This book is full of mystery, and the fantastic - the old definition of fantastic, which just means 'involving a lot of fantasy'. Lots of ghosts, a djinn, premonitions, ghosts, demons and angels, insanity, and every now and then a ghost. Not a shred of science.
It's a bit dated as well, probably has been from the start - some of the writers had been dead for 30 years when it was first published. The only story that surprised me was (of course) the one by Agatha Christie. Still, all in all, it wasn't bad, just not science fiction. Or exciting (spannend).
If mysteries with closed rooms, suspicious characters with eyes that seem to glow now and then, and maybe a ghost here and there are your cup of tea, you'll love it. If you're looking for spannende science fiction, keep looking.
Some good ones, some less interesting. You can tell it's mystery writers playing with the fantastical rather than SF or fantasy writers doing mystery's as a lot of the time the fantastical elements aren't that interesting.
