A dim light, which seemed to come from the rear, brought out the menacing figure plainly. One arm was half raised as if to strike. It was evident that the assassin was in doubt, since the headboard shaded the bed, as to whether the eldest brother or the little girl was stretched before him. The next instant he knew, for the eldest brother twisted in agony at sight of the arm poised above him and uttered a groan.
Quick as a flash the figure swayed toward him and the arm descended. But the eldest brother was quicker. He rolled sidewise, and at the same time struck out with his right hand. There was the sound of a dull blow not made by his fist, a scream from the little girl, and the thump of the eldest brother's body as he struck the floor on the farther side of the bed.
Intense stillness followed. The eldest brother, a revolver in either hand, got cautiously to his knees and peered across to where his assailant had stood. The dim light was gone now, however, and he could make out nothing. He waited, holding his breath, to see if any one were creeping upon him from under or around the bed. Hearing nothing but a sob from the little girl, he at last arose to his feet, his eyes and his weapons on the alert, and stepped back against the wall. Then he sidled along until, having passed the boarded-up window and two corners, his knees struck the cot.
"Don't be afraid," he said, squatting instantly to one side to dodge any bullet or knife that might be guided by his voice. After another short wait he added, "I think he's gone. Light the lamp."
While the match flickered in the little girl's hand, the eldest brother again moved eyes and pistols in a half-circle. But as the lamp was lifted and its light dispelled the darkness, he saw that they were alone. To remove every doubt, he looked under the bed and the cot and behind the headboard. When his search was completed he sat down on the rawhide-bottomed chair, trembling, enraged, and mystified.
"Am I crazy?" he asked in a low voice. "I was sure there was a man in here. But if there was, how'd he get out?"
"I heard some one," whispered the little girl. She was very pale, and kept close beside him for protection.
The eldest brother thought a moment. Then he jumped up and strode over to the bed. "Bring the lamp," he said.
Together they examined the covers. Only the top one had been turned down. Now it lay as the eldest brother had tossed it when he rolled out upon the floor. The other blankets were undisturbed. He ran his fingers over them carefully.
Suddenly he uttered a cry and began to fold them back swiftly, finding on each the trace he sought. When the mattress was at last laid bare, he pointed to a narrow slit that did not penetrate to the under side.
