These thoughts consumed the time for the sheriff until his horse had labored up the height, and he came to the little plateau where so much had happened outside of his ken.  And there he saw Bill Sandersen, with the all-seeing sun on his dead eyes.

For a moment the sheriff could not believe what he saw.  Sandersen was, in the phrase of the land, “Sinclair’s meat.”  It suddenly seemed to him that Sinclair must have broken from jail and done this killing during the night.  But a moment’s reflection assured him that this could not be.  The mind of the sheriff whirled.  Not Sinclair, certainly.  The man had been dead for some hours.  In the sky, far above and to the north, there were certain black specks, moving in great circles that drifted gradually south.  The buzzards were already coming to the dead.  He watched them for a moment, with the sinking of the heart which always comes to the man of the mountain desert when he sees those grim birds.

It was not Sinclair.  But who, then?

He examined the body and the wound.  It was a center shot, nicely placed.  Certainly not the sort of shot that Cold Feet, according to the description which Sinclair had given of the latter’s marksmanship, would be apt to make.  But there was no other conclusion to come to.  Cold Feet had certainly been here according to Sinclair’s confession, and it was certainly reasonable to suppose that Cold Feet had committed this crime.  The sheriff placed the hat of Sinclair over his face and swung back into his saddle; he must hurry back to Sour Creek and send up a burial party, for no one would have an interest in interring the body in the town.

But once in the saddle he paused again.  The thought of the schoolteacher having killed so formidable a fighter as Sandersen stuck in his mind as a thing too contrary to probability.  Moreover the sheriff had grown extremely cautious.  He had made one great failure very recently—­the escape of this same Cold Feet.  He would have failed again had it not been for Arizona.  He shuddered at the thought of how his reputation would have been ruined had he gone on the trail and allowed Sinclair to double back to Sour Creek and take the town by surprise.

Dismounting, he threw his reins and went back to review the scene of the killing.  There were plenty of tracks around the place.  The gravel obscured a great part of the marks, and still other prints were blurred by the dead grass.  But there were pockets of rich, loamy soil, moist enough and firm enough to take an impression as clearly as paper takes ink.  The sheriff removed the right shoe from the foot of Sandersen and made a series of fresh prints.

They were quite distinctive.  The heel was turned out to such an extent that the track was always a narrow indentation, where the heel fell on the soft soil.  He identified the same tracks in many places, and, dismissing the other tracks, the sheriff proceeded to make up a trail history for Sandersen.
