"The complaint is a serious one, Herr Captain-General. It is so serious, and affects such deep interests, that, as you see, it is deemed inadvisable to place it before a military tribunal. But it is also felt that the complaint in itself is not all; that there is other matter of even greater importance lying behind it. Thus you have been summoned to make your explanations--here." The cold eyes of the man were turned from Von Salzinger upon a document lying on the table. Just for a moment his hard voice ceased from stirring the echoes of the vaulted chamber. But it was only for a moment. The next he was reading from the paper before him. "It appears that on Prince von Hertzwohl's last visit to Borga, when he was conveying thither his relative, his most important engineer, for the rectification of certain defects in his new light, you displayed towards him the gratuitous discourtesy of refusing the Prince's guarantee of his relative, and sought to submit the man to the interrogatory customary where there is some doubt of a visitor's credentials. The Prince, somewhat naturally, refused to submit to such an indignity, and left the arsenal. Whereupon you persisted in your attitude, and even went so far as to endanger the Prince's valuable life by opening the secret batteries upon his vessel--a course which was utterly unwarranted in view of the Prince's identity and position. It is necessary that you should now state your story of this affair without any reservations." [Illustration: "The Complaint is a Serious One."] Von Berger's charge was coldly formal. It was also distinctly threatening in its final pronouncement. The arrogant Von Salzinger was bitterly forced to the reflection that he might expect small enough mercy if he failed to convince with his explanation. That which disturbed him more, however, was the identity of at least one of the men to whom he must explain. He had counted on a military tribunal, where his rank and the nature of his office would count. He felt that these things would by no means count here. But he dared not display any misgiving. He knew the value of promptness and brevity, with, at least, one of his audience. So he replied-- "In every detail the complaint is accurately outlined. But it avoids entirely Prince von Hertzwohl's offence." "Offence?" The interrogation came sharply from the man at the head of the table, who was almost lost to Von Salzinger's view behind the bulk of the oil-lamp which lit the scene. "It was his right, just as it would have been your right, sir," Von Salzinger replied daringly, "to submit to the discipline of the place, a discipline which has been ordered by those who have a right to order such things. The complaint must come after obedience, not after open defiance of Berlin's most imperative orders. That is the case of Prince von Hertzwohl. I could not have acted otherwise than I did in the interests of our greatest of all State secrets."
