He breathed slowly and deeply of the dry, clean wind, rose, and stretched his tired muscles, and turned in. So accustomed had he become to the heat that scarcely had he stretched out on the cot before he was asleep. And Bob was a sound sleeper. The sides of the shack were open above a three-foot siding of boards, open save for a mosquito netting. An old screen door was set up at the front, but Bob had not even latched that. If one was in danger out here, he was simply in danger, that was all, for there was no way to hide from it.
A little after midnight two Mexicans crept along on all-fours between the cotton rows at the edge of Bob's field. At the end of the rows, fifty yards from the shack, they crouched on their haunches and listened. The wind shook the tall rank cotton and rustled the weeds along the ditches. But no other sound. Nothing was stirring anywhere.
Bending low and walking swiftly they slipped toward the back of the shack. Their eyes peered ahead and they slipped with their hearts in their throats, trusting the Americano was asleep.
He was. As they crouched low behind the shelter of the three-foot wall of boards they could hear his breathing. He was sound asleep.
Slowly, on hands and knees, they crawled around the west side toward the entrance. In the right hand of the one in front was the dull glint of a knife. The other held a revolver.
Cautiously the one ahead tried the screen door—pushing it open an inch or two. It was unlatched. Motioning for the other to stand by the door, he arose, pushed the door back with his left hand very slowly so as not to make a squeak. In the right he held the knife.
Bob stirred in his sleep and turned on the cot. The Mexican stood motionless, ready to spring either way if he awoke. But the steady breathing of a sound sleeper began again.
The Mexican let the door to softly and took one quick step toward the bed.
Then with a wild, blood-curdling yell he fell on the floor. Something from above had leaped on him, something that enveloped him, that grappled with him. He went down screaming and stabbing like a madman. His companion at the door fired one shot in the air, dropped his gun, and ran as if all the devils in hell were after him.
The commotion awoke Bob. Instantly he sat up in bed, and as he rose he reached for a gun with one hand and a flashlight with the other. In an instant the light was in the Mexican's face—and the gun also.
