Recovered scarcely from our surprise at the explosion and the queer actions of the Secret Service man, we rushed after him as best we could, Craig leading.

He led the way to the little wireless room. The door was bolted on the inside, but we managed soon to burst it open.

I shall never forget the surprise which greeted us. In a chair, bound and gagged, as though he had been overcome only after a struggle, sat Petzka.

Mrs. Petzka threw herself frantically on him, tearing at the stout cords that held him.

"Nikola—what is the matter?" she cried. "What has happened?"

Through his gag, which she had loosened a bit, he made a peculiar, gurgling noise. As nearly as I could make out, he was struggling to say, "He came in—surprised me—seized me—locked the door."

Julia Rovigno stood rooted to the spot—utterly speechless.

There, surrounded by electric batteries, condensers, projectors, regulators, resonators, reflectors, voltmeters, and ammeters, queer apparatus which he had smuggled secretly on the Furious, before a strange sort of device, with a wireless headgear still over his ears, stood the owner of at least two of the liners of the belligerents which were to have made the dash for the ocean after he had succeeded by his new wireless ray device in removing the hostile fleet—Count Rovigno himself.
