Güldmar shook his head and drew his fuzzy white brows together in puzzled meditation—suddenly he started and struck his staff forcibly on the ground.

"I have it!" he exclaimed. "That old hag Lovisa is at the bottom of this!"

"By Jove!" cried Errington. "I believe you're right! What shall we do?"

At that moment, Lorimer, Duprèz, and Macfarlane came on the scene, thinking they had kept aloft long enough,—and the strange disappearance of the two girls was rapidly explained to them. They listened astonished and almost incredulous, but agreed with the bonde as to Lovisa's probable share in the matter.

"Look here!" said Lorimer excitedly. "I'm not in the least tired,—show me the way to Talvig, where that old screech-owl lives, and I'll go there straight as a gun! Shouldn't wonder if she has not forced away her grandchild, in which case Miss Thelma may have gone after her."

"I'll come with you!" said Errington. "Let's lose no time about it."

But Güldmar shook his head. "'Tis a long way, my lads,—and you do not know the road. No—'twill be better we should take the boat and pull over to Bosekop; there we can get a carriole to take two of us at least to Talvig—"

He stopped, interrupted by Macfarlane, who looked particularly shrewd.

"I should certainly advise ye to try Bosekop first," he remarked cautiously. "Mr. Dyceworthy might be able to provide ye with valuable information."

"Dyceworthy!" roared the bonde, becoming inflammable at once. "He knows little of me or mine, thank the gods! and I would not by choice step within a mile of his dwelling. What makes you think of him, sir?"
