She struck his face a second time. "I loved your brother. I wouldn't have done a thing like that." "Then what?" "I told you what you wanted to know. I don't have to tell you more. Now get out of here." She followed him to the door. "But you have to leave Mercury at once, you see," she said. "Bareen can't afford to let you live. Bareen will have you killed." "The way they tell it on Earth, Bareen's a loner. If he goes, the whole outfit folds and will play ball with Earth the way it ought to. Is that the way you see it?" "Yes, but--" "You thought I was here for revenge? I am, baby. Don't get any wrong ideas. But I've also got a job to do. Earth needs that chlorella." He opened the door. "Jansen--" "Well?" "Nothing. Just be careful." He laughed harshly and walked out into the darkness. * * * * * The man's name was Dinnison. He had the bunk next to Jansen's in the barracks and he, like Jansen, was a newcomer. He'd shipped to Mercury from the Venusian dust-desert in search of greener pastures. Jansen felt sorry for him, then ruthlessly beat down the feeling. He had no time for pity. While it was still dark he followed Dinnison outside the barracks and thrust a mugging arm around his neck. Dinnison struggled, his arms flailing, his legs drumming. Once he almost broke loose, but Jansen held him until he had lost consciousness. _A day_, Jansen thought. _Bareen knows I'm here, so all I can expect is a day now._ He dragged Dinnison into a storage shed. The slight effort left him drenched with sweat, despite the insulsuit. He found rope and bound Dinnison, then took tape from his pocket and gagged him. Ten minutes later he returned to the barracks with Dinnison's identification papers. _Andrew Dinnison_, he thought. _I'm Dinnison now._ Bareen's men would be looking for Frank Jansen, he knew. But unless Wendy Hilliard told them, they wouldn't know what Jansen looked like. _I'm Dinnison...._ He slept poorly. He dreamed but in the morning did not remember his dreams. When he awoke, Mercury had wobbled sufficiently for the twilight zone to be in sunlight again. "Rise and shine, men!" a supervisor's voice blared over the loudspeaker. "Got some gunk to harvest!" Jansen watched the men get up, groaning and complaining, in the barracks. Gunk was the supervisor's word for chlorella, Jansen thought. Looking at the men he decided they had other words for it, none of them printable. For, although the pay was good, it was sheer hell working on Mercury and the average employee at the chlorella bogs didn't stay more than three months.
