There was a three-day-old moon in the sky when the last colors faded in the west. When darkness fell it was already low. It gave little light; not much more than the stars alone. It did help Lockley while it lasted however. He knew the terrain about Boulder Lake but not in detail. And it would not be wise for him to move openly to wreak destruction on the enemies of his nation.
He used the moonlight for his approach by the least practical route to the lake. When it dimmed and went behind the mountains, he continued to climb, sliding dangerously, then descend and climb again as the rough going demanded. His mind was absorbed with reflections upon what he meant to do. The wrecks on the highway would have given notice to the invaders that he could do damage. They would take every possible precaution against him.
