"You can't just go and let me die!"
"I can and must," Williams 4 said sadly. "I am only a robot, Mr. Morrison. I was made by men, and naturally I partake of some of their sensibilities. That's as it should be. But I also have my limits, which, in their nature, are similar to the limits most humans have on this harsh planet. And, unlike humans, I cannot transcend my limits."
The robot started to climb into the whirlpool. Morrison stared at him blankly, and saw beyond him the waiting wolfpack. He saw the soft glow of several million dollars' worth of goldenstone shining from the ravine's walls.
Something snapped inside him.
With an inarticulate yell, Morrison dived, tackling the robot around the ankles. Williams 4, half in and half out of the 'porting vortex, struggled and kicked, and almost succeeded in shaking Morrison loose. But with a maniac's strength Morrison held on. Inch by inch he dragged the robot out of the vortex, threw him on the ground and pinned him.
"You are disrupting the mail service," said Williams 4.
"That's not all I'm going to disrupt," Morrison growled. "I'm not afraid of dying. That was part of the gamble. But I'm damned if I'm going to die fifteen minutes after I've struck it rich!"
"You have no choice."
"I do. I'm going to use that emergency telephone of yours."
