e led her carefully past the house. It was a fairly typical fazenda dwelling, if more substantial than most. It was wholly unpretentious, with whitewashed walls, and the effect of grandeur it would give to natives of this region would come solely from the number of buildings. There were half a dozen or more.

"I killed four men," repeated Bell coldly. "And I'm damned glad of it. That scream we heard.... I know pretty well what happened here last night. Remember, Ribiera spoke of using a beam-wireless to make his report. He must have had a short-wave beam set somewhere on the outskirts of Rio, aimed at whatever headquarters he reports to. He's going up to that headquarters some time to-day, by plane, of course. He needed emergency landing fields along the route, and here he picked out a native and made him a sub-deputy. Charming...."

Moving past the buildings, Paula caught sight of massive wooden bars set in the side of a building. Something crumpled up and limp lay before them.

"Don't look over there," said Bell harshly. "There was a woman in this house and she told me what happened, though I'd guessed it before. The sub-deputy was here last night with a party of friends. Newly enslaved, some of them. He entertained them.... Up at Ribiera's place a girl told me she and her husband had been shown a Secret Service man. He went mad before their eyes. It was an object-lesson for them, a clear illustration of what would happen to them if they ever disobeyed. I imagine that something of the sort is used by all The Master's deputies to convince their slaves of the fate that awaits them for disobedience. The local man had brought a party up to watch two men go mad. After that sight they'll be obedient."


e reached a shed, huge, but in disrepair. Monster doors were ajar. Bell heaved at them and swung them wide. A small, trim, two-seated plane showed in the shadowy interior.

"This is for emergency use," said Bell grimly, "and we face an emergency. I'll get it out and load it up. There's a dump of gas and so on here. You might look around outside the door, in case the one man who got away can find someone to help stop me."

He set to work checking on fuel and oil. He loaded extra gas in the front cockpit, a huge tin of it. Another would crowd him badly in the pilot's cockpit in the rear, but he stowed it as carefully as he could.
