Suddenly there came a flash of light straight ahead. Ernol had reached the outer corridor. And the doctor heard a great commotion going on outside the door in the ravine; a smashing and thudding, which filled the corridor with noise. Next second the door gave way, and simultaneously young Ernol leaped into the niche behind the thing which the doctor thought a machine gun. Another second, and he had the device in operation.
From its muzzle shot a thin stream of fire, which extended the whole length of the corridor. It lighted up everything with a bluish-white glare, revealing a mob of men at the door. They fell back, yelling with pain, some of them dropping in their tracks. And all the while the apparatus was dealing, not a shower of bullets, but a streak of liquid fire, which hissed and screamed like the blast from an oxygen blow-pipe.
But it was all over in a second or two. A noise from behind, and young Ernol started up suddenly, only to find himself in the grip of a veritable giant of a man. His struggles were simply useless. In a moment he was being carried bodily back into the hall, which the doctor saw was now lighted as before.
On one side, lined up amid a mass of wrecked chairs, stood most of the workers at bay. On the other were four men with small boxlike devices, such as Billie had already seen in the hands of Powart's guards, and which were kept trained threateningly upon the crowd. On the platform stood Ernol, now quite helpless in the grasp of two stalwart fellows.
The mob from the door poured in. Immediately they made captors of all the workers, who had precious little to say. Apparently they had been warned. The doctor also concluded that the capture was a piece of treachery, in which bribery had been employed.
Two minutes later young Ernol was placed in a large passenger flier, which the doctor labeled "Black Maria." Presumably the elder radical was taken in another; at any rate after another flight in the darkness, father and son shortly found themselves together again.
They were now in the drawing-room of some private residence, concluded the doctor. This puzzled him somewhat until, after a brief wait under the eyes of a half-dozen guards, the two radicals were taken into another room.
Here, lying on a couch, was a man whom the doctor soon identified. He was none other than Mona's patient, Eklan Norbith, the commission's deputy in Calastia. He was a burly, dark-featured fellow; and even though rigid in his plaster cast, he looked competent and formidable.
"Ernol," said he in a heavy, domineering voice, "there is no need to state the case to a man of your intelligence. You gave your word to stop your teachings; you have been caught in the act. Frankly, I rather thought you would do it; that is why I am here to-night. I want—to deal with you personally."
He paused for breath, and then went on, still ignoring the student, "Ernol, you know what I want. I want those photographs; and what is more, I am going to have them. You must have passed them to some one who escaped in the confusion; they have not been located on any one who has been captured, nor were they hid in the hall. Now I will give you exactly ten seconds [Footnote: For the sake of clearness, the Capellan second, whose actual length is of course unknown, is used here as though it were uniform with earth standards.] to tell me what you did with them."
