An Arrest.
The Santa Fe trail was far too exposed to be safely travelled alone and in broad daylight, but Keith considered it better to put sufficient space between himself and those whom he felt confident were still watching his movements from across the river.

How much they might already suspicion his discoveries he possessed no means of knowing, yet, conscious of their own guilt, they might easily feel safer if he were also put out of the way.

He had no anticipation of open attack, but must guard against treachery.

As he rode, his eyes never left those far-away sand dunes, although he perceived no movement, no black dot even which he could conceive to be a possible enemy.
