Karpin stood in the middle of the room, a small revolver in his hand. "Shut the door," he said.

I obeyed, moving slowly. I didn't want that gun to go off by mistake.

"Who are you?" Karpin demanded. The M&R man had been right. Ab Karpin was a dead ringer for all those other prospectors I'd seen back at Atronics City. Short and skinny and grizzled and ageless. He could have been forty, and he could have been ninety, but he was probably somewhere the other side of fifty. His hair was black and limp and thinning, ruffled in little wisps across his wrinkled pate. His forehead and cheeks were lined like a plowed field, and were much the same color. His eyes were wide apart and small, so deep-set beneath shaggy brows that they seemed black. His mouth was thin, almost lipless. The hand holding the revolver was nothing but bones and blue veins covered with taut skin.

He was wearing a dirty undershirt and an old pair of trousers that had been cut off raggedly just above his knobby knees. Faded slippers were on his feet. He had good reason for dressing that way, the temperature inside the dome must have been nearly ninety degrees. The dome wasn't reflecting away the sun's heat as well as it had when it was young.

I looked at Karpin, and despite the revolver and the tense expression on his face, he was the least dangerous-looking man I'd ever run across. All at once, the idea that this anti-social old geezer had the drive or the imagination to murder his partner seemed ridiculous.

Apparently, I spent too much time looking him over, because he said again, "Who are you?" And this time he motioned impatiently with the revolver.

"Stanton," I told him. "Ged Stanton, Tangiers Mutual Insurance. I have identification, but it's in my pants pocket, down inside this suit."

"Get it," he said. "And move slow."

"Right you are."

I moved slow, as per directions, and peeled out of the suit, then reached into my trouser pocket and took out my ID clip. I flipped it open and showed him the card bearing my signature and picture and right thumb-print and the name of the company I represented, and he nodded, satisfied, and tossed the revolver over onto his bed. "I got to be careful," he said. "I got a big claim here."
