Looking down the wall, Albert wavered. Thinking back, he made up his mind. Fred Kemmer was disturbed. By all the rules, Albert Johnson should be dead. But Shifaz had failed, and that fool guard had to call in the medics. It was going to be harder to get at Johnson, now that he was in the infirmary, but he had to be reached. One might buy off an agent who was merely checking on tax evasion, but tobacco was another matter entirely. Kemmer wished he hadn't agreed to boss Operation Weed. The glowing dreams of promotion and fortune were beginning to yellow around the edges. Visions of the Penal Colony bothered him, for if the operation went sour, he would do the paying. He had known that when he took the job, but the possibility seemed remote then. He shook his head. It wasn't that bad yet. As long as Johnson hadn't communicated with anyone else and as long as he was still in company hands, something could be done. Kemmer thought a while, trying to put himself in Johnson's place. Undoubtedly the spy was frightened, and undoubtedly he would try to escape. And since it would be far easier to escape from the infirmary than it would be from detention, he would try as soon as possible. Kemmer's face cleared. If Johnson tried it, he would find it wasn't as easy as he thought. With characteristic swiftness, Kemmer outlined his plans and made the necessary arrangements. A guard was posted in the hall with orders to shoot if Johnson tried the door of his room, and Kemmer himself took a stand in the building across the street, facing the hospital, where he could watch the window of Albert's room. As he figured it, the window was the best bet. He stroked the long-barreled blaster lying beside him. Johnson still hadn't a chance, but these delays in disposing of him were becoming an annoyance. Cautiously, Albert tried the grating that covered the window. The Antarian climate had rusted the heavy screws that fastened it to the casing. One of the bars was loose. If it could be removed, it would serve as a lever to pry out the entire grating. Albert twisted at the bar. It groaned and squealed. He nervously applied more pressure, and the bar moved slowly out of its fastenings. The Zark observed his actions curiously. Now why was its host twisting that rod of metal out of the woodwork? It didn't know, and it was consumed with curiosity. It had found no way to communicate with its host so
