Hazletine's belief, therefore, was that by shadowing the Sioux he had a good chance of securing the information that would overturn all the calculations of the abductors.
But this task was tenfold more delicate than would seem at first, for not only had the cowman to learn the whereabouts of the Sioux, but he must do it undetected and dog the fellow without discovery on his part.
When it is remembered that Motoza would be on the alert against this, one is almost ready to declare the cowman had attempted an impossible thing.
When he left his young friend, however, it was with the firm purpose of doing, or rather trying to push through this purpose.

Within a hundred yards of the point where he left Jack the guide had a glimpse of what may be called the shadow of a movement.

Something flickered among the rocks a short distance ahead and then vanished before he could identify it.
But he knew what it meant.

Some one was watching him.

If the watcher was not Motoza or Tozer, he was an ally of theirs.
