"Must have been a rock or something, sis. Moonlight plays queer tricks you know. Don't let's make the situation any worse by imagining things."

"It was not imagination," repeated Peggy stoutly.

But Roy, perhaps because he did not wish to, would not admit the possibility of Peggy's vision being correct.

A long, loud cry like the laughing of an imprisoned soul cut the stillness startlingly.

"Ki-yi-yi-yi-o-o-o-o-o-o-o-o!"

"Coyotes!" laughed Roy, "that's what you saw."

Peggy said nothing. The sudden sharp sound had rasped her overwrought nerves cruelly.

"Ki-yi-yi-yi-o-o-o-o-o-o-o-o!"

The demoniacal laughing, half howl, half bark, cut the night again.

This time it came from a different direction. From other grim peaks the cry was caught up. It seemed that the creatures were all about them.
