“I’m afraid it’s no use,” Bob panted as he stopped to rest. “Either they didn’t come this way or else they were clever enough not to leave a trail.”

“I think your first guess is right,” Jack declared. “I don’t see how anyone could get through this thick woods in the dark without leaving some sign.”

“Shall we turn back?”

“After what she said?”

“I know, but—”

“No buts about it. Let’s keep at it. It’s the only thing to do.”

“All right, come on.”

They had gone but a few feet when Jack’s keen eyes caught sight of something white caught on an old stump. With a low cry he snatched it up and held it out to Bob.

“It’s hers,” he declared.

“Are you sure?” Bob asked looking closely at the small handkerchief.
