3. The cover was fully black and “puffy” or 3D with white or silver lettering of the title…it may’ve had red eyes as well. I cannot recall the author or the title. I could have sworn it had the word “beast” in it, like Bloodbeast and seem to remember it was just one word in the title. I’ve tried googling in all sorts of ways but with no luck. In the story, the beast is a wolf-like creature shredding people in the lake/outdoorsy town and the sheriff-type guy was on the hunt of it. The book would primarily use the sheriff’s perspective I believe, then go into italics when telling the story from the perspective of the wolf-monster (who I think was female).
4. The cover has a red-haired woman with a skeletal hand, holding a bloody knife. In the beginning she kills her step-mother with a scorpion and I think later on in the book she kills someone else with a scorpion.
5. Centered around some sort of scientific or military expedition or research group. Of course there was a creature at some point. Based on what I remember of the book, it was a relatively slim volume (200 pages tops, I'd think), and I vaguely recall a pretty bland cover design (something blue and white?) that leads me to believe the publication had to be no later than the early-mid 1970s
