Bell managed the barest flicker of a smile. Arrest, of course. Detention, most courteously arranged, while the Ambassador was communicated with. And Ribiera. "_Give me dismiss_," he tapped on his knee. The gentleman in the thick spectacles ran his finger thoughtfully about the edge of his collar. In the Trade that is a signal of many varied meanings. A hand across the throat in any fashion means, "Clear out, your job is finished," "Save your skin as best you can," and "Get away without trying to help me," according to circumstances. In this case it relieved Bell of all future responsibility. He yawned, tapping his lips with the back of his hand, signaled for a stop of the car, and got out. Five minutes later he had signaled a taxicab and given Ribiera's address. In six minutes he was being whirled toward the one house in all Rio de Janeiro from which his chance of a safe departure was slightest. In little more than half an hour he had dismissed the cab and was gazing placidly into the startled eyes of the doorman. The doorman, like all of Rio where Ribiera was known and feared, knew that Bell was being hunted. Bell handed over his card with an inscrutable air. "The Senhor Ribiera," he said drily, "returned to the city last night. Present my card and say that I would like to speak to him." * * * * * The doorman ushered him inside and summoned the major-domo, still blinking his amazement. And the major-domo blinked again. But Bell followed with the air of an habitué, as he was again ushered into the luxurious salon in which he had once been offered a drugged drink. Again he sank down in a softly padded chair and surveyed the pictures and the minor objects of decadent art about him. Again he lighted a cigarette with every appearance of ease, and again had the impression of eyes upon him. The major-domo appeared, somewhat agitated. "The Senhor Ribiera," he said harshly, "will see you only if you are not armed. He requires your word of honor." Bell smiled lazily. "I'll do better than that," he said languidly. "I haven't had time to buy a revolver. But the automatic he had put out of commission is in my pocket. Present it to him with my compliments." He handed over the weapon, butt first. The major-domo blinked, and took it. Bell sat down and smiled widely. He had been expected to be uproarious, to attempt to force the major-domo to lead him to Ribiera. And, of course, he would have been led past a perfectly planned ambush for his capture--but he might have killed the major-domo. Which would not disturb Ribiera, but had disturbed the servant. * * * * * Bell smoked comfortably. And suddenly hangings parted, and Ribiera came into the room. He smiled nervously, and then, as Bell blew a puff of smoke at him and nodded casually, he scowled.
