The cab whirled past the crowded sidewalks. Incredible numbers of people, with an incredible variation in the shades of their complexions, moved to and from with the peculiar aimlessness of a Brazilian crowd. A stout and pompous negro politician from Bahia, wearing an orchid in his button-hole, rubbed elbows with a striking blonde lady of the sidewalks on his left, and forced a wizened little silk-hatted parda—approximately an octoroon—to dodge about him in order to progress. A young and languid person, his clothes the very last expiring gasp of fashion, fingered his stick patiently. He wore the painstakingly cultivated expression of bored disillusionment your young Brazilian dandy considers aristocratic. It was very probable that he shared a particularly undesirable bedroom with four or five other young men in order to purchase such clothing, but then, farenda fita—making a picture—is the national Brazilian sport.
Bell lighted a cigarette. It was not wise to regard the secretary of this particular taxi too closely, but if his face had been thickly smeared with coal dust, and if he had had a two weeks' beard, and if he had been seen on the forecastle of the Almirante Gomez, one would have deduced him to be a stoker who had not used the name of Jamison.
The cab reached the Beira Mar, and turned to take the long route about the bay. It is one of the most beautiful views to be found anywhere, and tall apartment houses have been built along its whole length to capitalize the scenery. True, the more brightly-colored ladies of the capital have established themselves in vast numbers among these apartment houses, but in their languid promenades they add—let us say—the beauties of art to those of nature.
A voice spoke from the chauffeur's seat.
"Bell."
"Right," said Bell without moving. His eyes flickered, however, and he found the device Jamison had inserted. A speaking-tube of sorts. Not especially efficient, but inconspicuous enough. He stirred listlessly and got his lips near it.
"All right to talk?" he asked briefly.
"Shoot," said Jamison from the secretary's seat beside the chauffeur. "This man doesn't understand English, and he thinks I'm in a smuggling gang. He expects to make some money out of me eventually."
Bell spoke curtly, while the taxi rolled past the Morro da Gloria with its quaint old church and went along the winding, really marvelous driveway past many beaches, with the incredibly blue water beyond.
"Canalejas is out of town," he said. "It isn't known when he'll be back. I met his daughter at a dance at our Embassy here, and she told me. We didn't dare to talk much, but she's frightened. Especially after what happened to Ortiz. And I've met Ribiera, whom Ortiz named."
"I've been looking him up," growled Jamison through the speaking-tube.
Bell flicked the ash from his cigarette out the door, and went on quietly.
"He's trying to get friendly with me. I've promised to call at his house and have him take me out to the flying field. He has two planes, he tells me, a big amphibian and a two-seater. Uses them for commuting between Rio and his place back inland. He went out of his way to cultivate me. I think he suspects I'm trying to find out something."
"Which you are," said Jamison dryly. "You've found out that Ortiz was right at least about—"
Bell nodded, and frowned at himself for having nodded. He spoke into the mouthpiece by his head with an expressionless face.
"He's practically fawned upon by a bunch of important officials and several high ranking army officers. Suspecting what I do, I think he's got hold of a devil of a lot of power."
Jamison scowled in a lordly fashion upon a mere pedestrian who threatened to impede the movement of the taxicab by making it run over him.
"Ortiz," said Bell quietly, "told me he'd been poisoned, and treason asked as the price of the antidote. I've heard that the Brazilian Minister for Foreign Affairs went insane six months ago. I heard, also, that it was homicidal mania—murder madness. And I'm wondering if these people who fawn upon Ribiera aren't paying a price for—well—antidotes, or their equivalent. The Minister for Foreign Affairs may have refused."
"You're improving," said Jamison dryly. The taxi rounded a curve and a vista of sea and sand and royal palms spread out before it. "Yes, you're improving. But Ortiz spoke of Ribiera only as a deputy of The Master. Who is The Master?"
"God knows," said Bell. He stared languidly out of the window, for all the world to see. A tourist, regarding the boasted beauties of the Biera Mar.
"A deputy," said Jamison without emotion, "of some unknown person called The Master poisoned Ortiz in Buenos Aires. And Ortiz was an important man in the Argentine. Ribiera is merely the deputy of that same unknown Master in Rio, and he has generals and state presidents and the big politicians paying court to him. If deputies in two countries that we know of have so much power, how much power has The Master?"
Silence. The taxi chugged steadily past unnoticed beauties and colorings. Rio is really one of the most beautiful cities in the world.
"It's like this," said Jamison jerkily. "Seven Service men vanish and one goes mad. You get two tips that the fate of Ortiz is the fate of the seven men—eight, in fact. We find that two men dispense a certain ghastly poison in two certain cities, at the orders of a man they call The Master. We find that those two men wield an astounding lot of power, and we know they're only deputies, only subordinates of the Master. We know, also, that the Service men vanished all over the whole continent, not in just those two cities. How many deputies has The Master? What's it all about? He wanted treason of Ortiz, we know. What does he want of the other men his deputies have enslaved? Why did he poison the Service men? And why—especially why—do two honorable men, officials of two important nations, want to tip off the United States Government about the ghastly business? What's it got to do with our nation?"
Bell flung away his cigarette.
"That last question has occurred to me too," he observed, and carefully repressed a slight shiver. "I have made a guess, which is probably insane. I'm going to see Ribiera this afternoon."
"He already suspects you know too much," said Jamison without expression.
"I am"—Bell managed the ghost of a mirthless smile—"I am uncomfortably aware of it. And I may need an antidote as badly as Ortiz. If I do, and can't help myself, I'll depend on you."
Jamison growled.
"I simply mean," said Bell very quietly, "that I'd really rather not be—er—left alive if I'm mad. That's all. But Ortiz knew what was the matter with him before he got bad off. I know it's a risk. I'm goose-flesh all over. But somebody's got to take the risk. The guess I've made may be insane, but if it's right one or two lives will be cheap enough as a price for the information. Suppose you chaps turn around and take me to Ribiera's house?"
There was a long pause. Then Jamison spoke in Portuguese to his companion. The taxi checked, swerved, and began to retrace its route.
"You're a junior in the Trade," said Jamison painstakingly. "I can't order you to do it."
Bell fumbled with his cigarette case.
"The Trade doesn't exist, Jamison," he said dryly. "And besides, nobody gives orders in The Trade. There are only suggestions. Now shut up a while. I want to try to remember some consular reports I read once, from the consul at Puerto Pachecho."
"What?"
"The consul there," said Bell, smiling faintly, "was an amateur botanist. He filled up his consular reports with accounts of native Indian medicinal plants and drugs, with copious notes and clinical observations. I had to reprove him severely for taking up space with such matters and not going fully into the exact number of hides, wet and dry, that passed through the markets in his district. His information will be entirely useless in this present emergency, but I'm going to try to remember as much of it as I can. Now shut up."
