The Beasts in the Void by Paul W.Fairman

Holloway was used to big game hunters and their expeditions to other worlds. But this trip was sheer madness--
There had been some trouble, Mason recalled, in clearing Holloway's first cruise. A party of five. Not to any established hunting ground but a D. U. thing.Destination Unknown, and they were always trouble.
Clearance had been made, though, and now-here was Holloway back again-dramatically of course-with one of his party dead and the other four in trance-like stupors. Strange.
