The Long Walk...

Robert hit the ground hard. His head, stuffed uncomfortably in the soaking, sweaty burlap bag, slammed into the hot earth. He heard the click of a knife blade locking into place. As his heart quickened, he felt a tug on the rope binding his hands. The cords gave way and he was released. He tore the bag from his face, ready to breathe in the hot dry air, but was met only by his trusted associate. Alexander struck the doctor and rolled over in the dust, lying face up.
"Farewell, gentlemen!" called Professor Lambert, from the driver's seat. He sped off in a cloud of dust, leaving Robert and Alex behind. Coughing, Robert clamored to his feet and watched the Professor's red Ferrari shrink and blend with the rising heat waves. He brushed the dust from his shirt and looked at his friend on the ground.
"Well, that's it, I suppose," he said. He turned back to watch the last bit of scarlet sports car fade away. Waiting for his comrade to move, he brushed a bit more dust from his shirt, adjusted his collar and ran his hand through his sweaty hair. Disgusted, he rubbed the mess off on his pants. "Alex?" He asked, cautiously, looking the man over. There was no movement. "Alex!" The man did not stir. Robert fell to his knees and rolled him onto his back. There was a large wet spot and a hole in his shirt. Robert ran his finger along the edge of the wet spot and it came away, stained red. His heart raced and the sweat on his brow took an icy chill to it. His ears buzzed as if a gun had gone off near his head. And a voice came.
"Hello, Doctor," it said, familiarly. "By now, I'm long gone and you've discovered the little present I left inside your friend." Robert clenched his fists and his blood began to froth in his veins. "There is a small jug of water about a hundred miles due East. The sun his now at Solar Noon. If you wait a few minutes and calm down, you should make it to the water by dawn. I wish you the best of luck, my old friend. Now, rest up. You've got a long walk ahead of you."
Robert fell on his back, shaking with the heat both inside and out. He let out a roar that shook the stones at his feet and slammed his fists into the ground, sending bits of caked mud flying. As he lay there on the ground, breathing heavily, sweat pouring down his face, the sun glaring down at him, he heard a quiet ticking.
"Oh, and one more thing," the professor's voice said. "You'd better get going," The ticking grew louder. Robert leapt to his feet and sprinted away as his partner exploded into a ball of flame and body parts, some of which struck his back. As the carnage fell, he turned around and studied the smoking, bloody crater for a moment. A bit of scalp landed next to his feet and a small mist of blood had coated his face. Robert lowered his head. "Good-bye, Alex," he said, and he turned to the east, beginning the long walk.
