he car turned the corner, and he added dryly:

"Your servants, Ribiera, will warn your more prominent slaves of my intention of going on board a yacht. Preparations will be made to stop every pleasure boat and search it for me. So ... tell your chauffeur to swing about and make for the flying field. And tell him to drive carefully, by the way. I've still got these guns on a very fine adjustment of the trigger-pressure."

Ribiera croaked the order. Bell was exactly savage enough to kill him if he did not escape.

For twenty minutes the car sped through the residential districts of Rio. The sun was high in the air, but clouds were banking up above the Pao d'Assucar—the Sugarloaf—and it looked as if there might be one of the sudden summer thunderstorms that sometimes sweep Rio.

Then the clear road to the flying field. Rio has the largest metropolitan district in the world, but a great deal of it is piled on end, and Rio itself built on most of the rest. The flying field is necessarily some miles from even the residential districts, for the sake of a level plain of sufficient area.

The car shot ahead through practically untouched jungle, interspersed with tiny clearings in which were patchwork houses that might have been a thousand miles in the interior instead of so near the center of all civilization in Brazil. Up smooth gradients. Around beautifully engineered curves.
