hat happened then, happened quickly. A few crisp words in a low tone. A minor hubbub began suddenly back at the house. Canalejas climbed into the passenger's seat as if looking for something. And Bell presented his now useless automatic pleasantly at the head of the nearest staring mechanic, and while he froze in horror, scrambled up into the pilot's cockpit.

"Contact!" he snapped, and turned on the switch. The mechanic remained frozen with fear. "Damnation!" said Bell savagely. "I don't know the Portuguese for 'Turn her over'!"

He fumbled desperately about in the cockpit. Something whirred. The propeller went over.... Canalejas shot with painstaking accuracy, twice. The motor caught with a spluttering roar.

As a horde of running figures, servants and guests, running with the same desperation, came plunging out on the flying field from the shrubbery. Bell gave the motor the gun. The fast little plane's tail came up off the ground as she darted forward. Faster and faster, with many bumpings. The bumpings ceased. She was clear.

And Bell zoomed suddenly to lift her over the racing, fear-ridden creatures who clutched desperately at the wheels, and then the little ship shot ahead, barely cleared the trees to the east of the field, and began to roar at her topmost speed toward Rio.

CHAPTER V

he Trade—which does not exist—has its obligations and its code, but also it has its redeeming features. When a man has finished his job, he has finished it. And as far as the Trade was concerned, Bell had but little more to do. But after that—and his eyes burned smokily in their depths—there was much that he intended to do. He sat in one of the bondes of the Botanical Garden half of the street railway system of Rio, and absent mindedly regarded the scenery. This particular bonde was headed out toward the Lagoa Rodrigo de Freitas, by which salty mass of water Bell would meet Paula Canalejas. He would receive a package from her, which he would deliver to Jamison. And then he would be free, and it was his private intention to engage in an enterprise which was very probably a form of suicide. But there are some things one cannot dismiss with a sage reflection that they are not one's business. This matter of Ribiera was definitely one of them.
