That night Molly dreamed of dancing figures. Joyously she ran toward them, arms outstretched, her feet not touching the ground at all as she raced to join them. Then the air thickened and shimmered and the figures were distorted, and when one of them looked at her, the outline of her face was all wrong, her features wrong, one eye too high, her mouth bent out of shape. Molly stopped, staring at the grotesque face. She was drawn toward it relentlessly through the thick air that changed everything. She struggled and tried to hang back, but her feet moved, her body followed, and she could feel the resisting air close about her suffocatingly. The caricature of her own face grimaced, and the figure raised snake-like arms toward her. Molly came wide awake suddenly, and for several moments didn't know where she was. Someone was shouting.

It was Thomas, she realized, and Ben and Lewis were struggling with him, getting him out of his bunk, toward the bow of the boat, the canopied section. Harvey moved to the rear and gradually quiet returned, but it was a long time before Molly could go back to sleep.

By the third day the return trip had turned into a nightmare. The wind became gusty, more dangerous than helpful, and they no longer tried to use the sail. The current was swifter, the water muddy. It must have rained much more inland than it had in Washington. Also, the air had a chill that persisted until midday, when the sun became too hot for the warm clothing they had put on earlier. By sundown it was too cool for the lighter garments they had changed into at the lunch break. They were always too hot or too cold.

Ben and Lewis withdrew from the others and watched the sunset from a rise over the river. "They're hungry, that's part of the trouble," Ben said. Lewis nodded. "Also, Molly has started her menstrual period and she won't let anyone near her. She nearly bit poor Harvey's head off last night."

"I'm not worried about Harvey," Lewis said.

"I know. I don't know if Thomas is going to make it or not. I tranquilized him at dinner. I don't know from one day to the next what to expect from him."

"We can't carry a dead weight home with us," Lewis said grimly. "Even with strict rationing, food's going to be a problem. If he's tranquilized, he'll still need to eat, someone else will have to row for him.

"We'll take him back with us," Ben said, and suddenly he was in command. "We'll need to study him, even if he goes home in restraints."
