He called Goodheart to one side.  “As soon as it’s dark I’m goin’ in to find out what’s doin’.  We haven’t heard a murmur from these birds for hours.  Perhaps they’ve flown.  Anyhow, I’m goin’ to find out.”

“How many of us are goin’?”

“Just one of us—­Billie Prince.”

“If two of us went—­”

“It would double the chances of discovery.  No, I’m goin’ alone.  Maybe I can have a talk with Albeen or Yankie.  I don’t want to take ’em dead, but alive.”

“They’ll probably get you while you’re in there, Prince.”

“I don’t think it.  But if I’m not back by mornin’ you are in charge of this hunt.  Use yore judgment.”

The deputy ventured one more protest, but his chief vetoed it.  Billie had decided what to do and argument did not touch him.

He did not take a rifle.  In the thick brush it would be hard to handle noiselessly and the snapping of a twig might mean the difference between life and death.  The sheriff slipped into the tangle of cat-claw, prickly pear, and mesquite, vanishing into the gloom from the sight of Goodheart.

On the back of an envelope Dumont had drawn for him a rough map of the valley.  It showed that the wooded arroyos ran together like the spokes of a wheel.  The judgment of Prince was that he must look for the men he wanted close to the angle of intersection.  Up one or the other of these draws it was likely they would make their dash for freedom, since otherwise they would have to emerge into the open.  Therefore, they would hold the base of the V in order not to be cut off from the chance of getting out of the trap.

The sheriff snaked forward, most of the time on his stomach or on hands and knees, for what seemed an interminable period.  Each least movement had to be planned and executed with precision.  He dared not risk the cracking of a dead branch or the rustle of dry foliage.  As silently as an Apache he wriggled through the grass.

Billie became aware of a sound to the left.  He listened.  It presently defined itself as a wheezing rattle halfway between a cough and a groan.

Toward it Prince deflected.  He knew himself to be now in the acute danger zone, and he increased if possible his precautions.  The moaning continued intermittently.  Billie wondered why, if this were the camp of the outlaws, no other sound broke the stillness.  Closer, inch by inch, making the most of every bunch of yucca and cholla, the officer slowly crept.

The figure of a man lay in the sand, the head resting on a folded slicker.  From time to time it moved slightly, and always the restlessness was accompanied by the little throat rattle that had first attracted the attention of the sheriff.  The face, lying full in the moonlight, was of a ghastly pallor.

Prince lay crouched behind a pinon till he was sure the man was alone.  It was possible that his confederates might return at any moment, but Billie could not let him suffer without aid.  He stepped forward, revolver in hand, every sense ready for instant response.
