A corridor turned off to the right. Homer hurried down it. At each door he looked inside. To whoever occupied the room he murmured a few words of apology in Wolof, the Sengalese lingua franca. The fourth office was empty.

Homer stood there before it for a long, agonizing moment, waiting for the right person to pass. Finally, the man he needed came along. About six feet tall, about a hundred and eighty; dressed in the local native dress and on the ragged side.

Homer said to him authoritatively, in the Wolof tongue, "You there, come in here!" He opened the door, and pointed into the office.

The other, taken aback, demurred.

Homer's face and tone went still more commanding. "Step in here, before I call the police."

It was all a mistake, of course. The Senegalese made the gesture equivalent to the European's shrug, and entered the office.

Homer came in behind him, closed the door. He wasted no time in preliminaries. Before the native turned, the American's hand lashed out in a karate blow which stunned the other. Homer Crawford caught him, even as he fell, and lowered him gently to the floor.

"Sorry, old boy," he muttered, "but this is probably the most profitable thing that's happened to you this year."

He stripped off the other's clothes, as rapidly as he could make his hands fly. The other was still out and probably would be for another ten minutes, Crawford estimated. He stripped off his own clothes and donned the native's.

Last of all, he took his wallet from his pocket, divided the money it contained and stuffed a considerable wad of it into the European clothing he was abandoning.
