"Don't know, Doc. Nobody's reported him."
"Then take a crew and search the ship. We were due back hours ago. He's in there somewhere."
"Sure, Doc." The guard disappeared through the lock. The man called Doc motioned Greg and Johnny through into the main cabin.
"What are you planning to do with us?" Greg demanded.
"You'll find out soon enough." Doc's mouth twisted angrily.
A guard burst into the cabin. "Doc, there's just nobody there! We've scoured the ship."
"You think he just floated away in his space suit?" Doc growled. "Find him. Tawney only needs one of them, but we can't take a chance on the other one getting back...." He broke off, his eyes on the viewscreen. "Did you check those scout ships?"
"No, I thought...."
"Get down there and check them." Doc turned back to the viewscreen impatiently.
Greg caught Johnny's eye, saw the big miner's worried frown. "Where is he?" he whispered.
