"Exactly, Dad. Purposeless destruction is a fetish of this people. Their psychology has an abnormal belief in terror. They judge everybody the same. You have seen it in a hundred ways. Except for this they are anything but fools. But in this they are almost childlike. They know they cannot stop the work in these yards. They know if they destroy a dozen sets of plans there will still be more forthcoming. They know all this, and are childishly, impotently furious. Their first thought is revenge, and then terrorizing. They think they can frighten us into abandoning the work, perhaps. I don't know. There is one thing certain: speculation on the matter is waste of your valuable efforts. Sparling is right; they have shown their hand. They will get no second chance on the same lines. They have achieved two weeks' delay. That is all they have achieved—here."

"Here?"

"Yes. I haven't had an opportunity of telling you before." Ruxton paused. A storm had gathered in his deep eyes. His fair, even brows were drawn. His father noted a sudden fullness in the veins at his temples. Then, in the midst of the affairs of the moment, he remembered his son's hurried rush to town, and its purpose.

Quite suddenly Ruxton leapt to his feet. He towered over the staunch figure of his father. His eyes had become hot and straining.

"Yes, what they have achieved here is futile. But what they have done elsewhere is—damnable," he cried, with hardly repressed fury. "I feel as if I should go mad. I've thought and thought till I can no longer think connectedly upon the matter. I am lost; utterly lost; groping like a blind man. She has gone. She's been spirited away, stolen; and God alone knows what suffering and torture she may not even now be enduring. I told you revenge and terror are the motives of these people. Their plans have fallen into our hands, and we are availing ourselves of them. Remember, the secrets we possess are the most precious of all the German Government's plans. They cannot undo that mischief, so they turn to revenge, for which they have an infinite capacity. Who are they going to be revenged upon? Us? Yes, as far as possible. Even our own lives may be threatened. But more than all they intend to hurt Von Hertzwohl and—all belonging to him. They mean to kill him, and possibly the others. But first they will use his daughter to get at him. Do you see? She will be tortured until she delivers him into their hands, and then—God knows."

He flung out his arms in a gesture of despair.

His father's eyes deepened in their anxiety. But the set of his strong mouth became firmer.

"Tell me just what has happened." The demand spoken so quietly had the effect desired.

Ruxton pulled himself together. His father watched the return of control with satisfaction.

He told the story of his journey to Wednesford calmly and quietly, without missing a detail. Sir Andrew listened closely, the seriousness of his attitude deepening with every fresh detail which pointed the certainty of foul play. At the conclusion of the story he was as gravely apprehensive as the other, and his sympathy for his boy's heart-broken condition was from the depths of his devoted heart.
