He ate and slept as he felt the need. There was plenty of food in the sick bay kitchen, and there is no need for a bed under gravity-less conditions.
After the engine was repaired, he set about getting the rest of the ship ready to move—if it would move. The hull was still solid, so the infraspace field should function. The air purifiers had to be reconnected and repaired in a couple of places. The lights ditto. The biggest job was checking all the broken leads to make sure there weren't any short circuits anywhere.
The pseudogravity circuits were hopeless. He'd have to do without gravity.
On the third day, he decided he'd better clean the place up. There were several corpses floating around, and they were beginning to be noticeable. He had to tow them, one by one, to the rear starboard air lock and seal them between the inner and outer doors. He couldn't dump them, since the outer door was partially melted and welded shut.
He took the personal effects from the men. If he ever got back to Earth, their next-of-kin might want the stuff. On the body of the imitation Rat, he found a belt-pouch full of microfilm. The report on the Rats' new weapon? Possibly. He'd have to look it over later.
On the "morning" of the fourth day, he started the single remaining engine. The infraspace field came on, and the ship began moving at multiples of the speed of light. Pendray grinned. Half gone, will travel, he thought gleefully.
If Pendray had had any liquor aboard, he would have gotten mildly drunk. Instead, he sat down and read the spools of microfilm, using the projector in the sick bay.
He was not a scientist in the strict sense of the word. He was a navigator and a fairly good engineer. So it didn't surprise him any that he couldn't understand a lot of the report. The mechanics of making a semi-nova out of a normal star were more than a little bit over his head. He'd read a little and then go out and take a look at the stars, checking their movement so that he could make an estimate of his speed. He'd jury-rigged a kind of control on the hull field, so he could aim the hulk easily enough. He'd only have to get within signaling range, anyway. An Earth ship would pick him up.
If there was any Earth left by the time he got there.
