“Got them—safe,” he said, and ran upstairs to the handsome library, where he unlocked a cabinet, touched a button and waited for a minute, before a little weird voice answered—

“Who is it?”

He gave his number to the questioner, and asked to be switched on to X987654321.

In a few minutes, in obedience to the modern magic of the telephone, there came another signal and question and satisfactory proof of identity, before the professor said sharply—

“Krakatoa. Come quick.”

“Hah!” sighed the operator, as he closed the little cabinet; “now for the old lady. Is the danger scotched or killed?”

He hurried down to the pantry, to find that the housekeeper had not moved; and as soon as he reached her side, he took her in his arms, while hers feebly clasped his neck.

“My poor old darling!” he whispered tenderly. “In much pain?”

“A good deal. My ankles are numbed. Is there any danger now?”

“Not for us, I think,” he said grimly. “There, hold still, and I’ll carry you up to the library;” and lifting her from the table as easily as if she had been a mere girl, he bore her up the stairs and laid her upon a couch, kneeling afterwards by her side to chafe her ankles and wrists in turn, while she told him all that he did not know.
