The figure of a woman, emerging into the full light of the moon, had caught Ruth's attention.

Percival turned quickly.

Together they watched the figure move swiftly across the Green toward them.

Suddenly it stopped, and then, after a moment, whirled and made off down the line of cabins, soon to be swallowed up by the gloom.
"Were you expecting some one ?" inquired Ruth, icily.
He was still looking intently into the far-reaching gloom.

Neither had spoken for many seconds.
