The children had taken up their industrious play again, and their mother had turned from the open doorway to hush the crying of Mateo's youngest in the cabin. Mateo called the children to him and patted them on the head, and the senora, their mother, brought candy and gave it to them. They ran off, sucking the sweets, gabbling gleefully to one another. Cliff Lowell had been right, nothing is so disarming as a woman and children about a place where secrets are kept. There had been no suspicion of Mateo's cabin and the family that lived there in squalid content. The incident was closed. But Johnny slumped down in the seat again and glowered through the little, curved windshield at the crisply wavering leaves beyond the Thunder Bird's nose. He was not a fool, any more than he was a crook. He was young and too confiding, too apt to take things for granted and let the other fellow do the worrying, so long as things were fairly pleasant for Johnny Jewel. But right now his eyes were open in more senses than one, and they were very wide open at that. There was something very radically wrong with this job. The fiction of legitimate news gathering in Mexico could no longer give him any feeling save disgust for his own culpability. News gathering did not require armed guards--not in this country, at least--and such mysteries as Cliff Lowell dealt in. The money in his possession ceased to give him any little glow of pleasure. Instead, his face grew all at once hot with shame and humiliation. It was not honest money, although he had earned it honestly enough. If it had been honest money, why should those soldiers go riding through the valleys, looking for him and his plane? It was not for the pleasure of saying howdy, if Johnny might judge from the hard-eyed glances of that one who had stopped in plain view. It was not honest money that he had been taking. Why, even the kids out there knew it was not honest! Look at Rosa, playing shrewdly her part of dumb shyness in the presence of strangers--and she thinking all the while how best she could lie to them, the little imp! It was not the first time she had shown her shrewdness. Why, nearly every time Cliff wanted to make a trip across the line, those kids climbed the hill to where they could look all over the flat and the near-by hills, and if they saw any one they would yell down to Mateo. If the interloper happened to be close, they had orders to roll small rocks down for a warning, so Cliff one day told Johnny with that insufferably tolerant smile. Cliff brought them candy and petted them, just for what use he could make of them as watchdogs. Would all that be necessary for a legitimate enterprise? Wouldn't the guards have orders to shut their eyes when an airplane flew high, bearing a man who gathered news vital to the government?
