The light in the cabin was off, but in the dim reflection from the corridor walls, Tim could see Wyckoff was lying in the bunk, which faced the door, on his back with the covers pulled up under his chin. "Asleep so soon, Sam?" asked Tim in a low voice.

"Not quite. What is it?"

"El Avery was just up. Said you looked exhausted and naturally I was a little worried. Had a check-up with the doctor recently?"

"No ... no ... don't worry about me," faintly.

"That's part of my job. We want everybody to get to Venus ready for a hard pull. Have you been studying too hard on the trip?"

"No. My job's not very important. Please don't worry about me."

"Mind if I turn on the light and have a little talk?" Tim reached for the switch of the reading lamp at the head of the bunk on his right.

"If you want to," reluctantly.

Tim clicked the switch and sat down on the foot of the bunk. "Finding the trip comfortable?" he smiled.

"I ... I suppose."
