"Come on," said the man with the briefcase shortly, "let's get out of here and find out what's what." He was going along the wall, pushing and rapping it. "How did they cop us, that's what I'd like to know. All I remember is hitting the bottom of that big dip, and then I was waking up in here." He stopped, then said sharply, "I hear something moving. My God! It sounds as big as an elephant."
Then the wall began to glide noiselessly and smoothly to the left, and he scuttled back to the knot of them, looking over his shoulder.
The entire wall slid sideways and vanished, leaving an open end to the room through which Summersby could see a number of large structures that seemed to be machinery, painted various colors. There was no sign of movement. He wondered, in a quiet, detached way, what sort of people might be out there.
"It sounded big," said the blond man again, and looked up at Summersby.
"I am six feet five," said Summersby bleakly. "Whoever it is will have to go some to top me."
An unknown thing moved beyond the room with a brief shuffling sound and then a hand came in through the open end. It was on an arm with a wrist the thickness of Summersby's biceps, an arm two yards long with no indication that it might not be even longer. The hand itself was a foot and a half broad, with a prehensile thumb at either side. Summersby did not notice how many fingers it had. The backs of the fingers and the whole great arm were covered with a thick gray-black thatch of coarse hair, and the naked palm was gun-metal gray. Between one thumb and finger it held a long green rod that was tipped by an ivory-colored ball.
There was no sign of anyone looking in, only the incredible arm and hand.
