"You need not be afraid," he said gently. "They will not touch you unless I order them." Jamison stared down at the little man whose collar he held firmly, with a Mills grenade dangling down at the base of his neck. "I wouldn't order them to attack, if I were you," he said coldly. "I haven't Bell's brains, but I have just as much dislike for you as he has." * * * * * They came to the harbor. Bell spoke again. "The carriage is to drive out to the end of one of the docks, and no one else is to go out on that dock." The Master relayed the order in his mild voice, but as the coachman obeyed him he clucked his tongue commiseratingly. "Senor Bell," he protested gently. "You do not expect to escape! Not after killing me! Why that is absurd!" Bell said nothing. He alighted from the carriage, his face set grimly, and stared ashore at the long, long row of terrified faces staring out at him. The whole waterfront seemed to be lined with staring faces. Wails came from that mass of enslaved human beings. "Hold him here, Jamison," he said drearily. "I'm going out to look at that big plane. There's a rowboat tied to the dock, here." He swung down the side into the dock and rowed off into the harbor, while the horses attached to The Master's carriage pawed impatiently at the wooden flooring of the dock. Bell reached the two planes anchored on the still harbor water. The smaller one had brought them down from Buenos Aires. The larger one had gone after the beached amphibian and brought it and Paula on to the city. Bell, from the shore, was seen to be investigating the larger one. He came rowing back. His head appeared above the dock edge. "All right," he said tiredly. "The Master has a rule requiring all his ships ready for instant flight. Very useful. The big plane is fueled and full of oil. We'll go out to it and take off." * * * * * Jamison lifted The Master to his feet and with a surge of muscles swept him down to the flooring of the dock. "Paula first," said Bell, "and then The Master, and then you, Jamison." "One moment," said The Master reproachfully. "It would be cruel not to let me reassure my subjects. I will give an order." Bell and Jamison listened suspiciously. But he spoke gently to the coachman. "You will tell the deputies," said The Master in Spanish, "that a month's supply of medicine for all my subjects will be found in my laboratory. And you may tell them that I shall return before the end of that time." The coachman's eyes filled with a passionate relief. "Now," said The Master placidly, "I am ready for our little jaunt." Paula descended the ladder and seated herself in the bow of the boat. Bell covered The Master grimly with his automatic as he descended, with surprising agility. Jamison came down last, and resumed his former grip on The Master's collar. Bell rowed out to the big plane. * * * * *
