I need help identifying a horror short story collection I read in the late 1970s.
The most memorable story was about a crew stationed on another planet (Mars, I think) that becomes infected and turned into murderous zombie-like beings.
The story features someone being killed with a scalpel in a medical lab. At the end of the story, the lone, uninfected crew member escapes onto the planet’s surface in a moon buggy-type vehicle.
The vehicle crashes. As his now inhuman pursuers close in, the uninfected crew member opts to kill himself by removing his helmet.
I found this grim story very disturbing at the time.
The only other story I recall any details about featured someone investigating a neighbor’s house and finding the occupant to be some kind of spider creature.
The book had several black & white illustrations in it, one of which was for this story, featuring a victim bound in spider webs.
This is a very tough one, I know. Anything you or your readers can come up with would be greatly appreciated.
Thanks very much,
