The Beasts in the Void by Paul W Fairman, Science Fiction, Fantasy 12+

📕 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.
