The other had pushed his shoulder gently around so that he faced the northwest.
"That isn't what I wanted you to look at. See anything else?" questioned Bob.
"See anything else! What—"
"A light!"
"A light! Where, for goodness' sake?"
"Over the top of that hill."
Dave peered eagerly through the gloom. Sure enough, a tiny glow was flaring against the blackness, sometimes disappearing, then coming into view again and shining as a faint reddish glimmer.
Some one was out there, and Bob Somers' lips framed the word, "Who?"
Dave shook his head.
