“There is nothing against you, sir. I am instructed to exercise the greatest consideration for you. A great deal, I may add, is left to my discretion, after all. Your wife, I am compelled to inform you, is charged with a very serious offence. In plain words, we have indisputable proof that she is and has been for several years in direct communication with the German Government through—”

“It is a damned, outrageous lie!” shouted Carstairs, furiously. “How dare you come here—”

“Just a moment, please,” interrupted the other sharply. “My instructions are to treat you with the utmost respect and consideration. I must ask you to accord me the same treatment. Will you send for your wife, or must I resort to the authority that—”

“For God's sake, man,—wait! Let me get this thing through my head. I—I—-will try to control myself. There has been some terrible mistake. Let us discuss the matter calmly. I can explain everything. We must spare her the mortification, the humiliation of being—Why, my dear sir, it would—kill her. She would not survive the—”

The agent held up his hand. “There is no mistake. It may be possible to spare her the disgrace, the ignominy of public exposure. That, sir, rests with her—and with you. We recognize your position, Mr. Carstairs. There is a disposition on the part of the authorities to protect you. With that object in view, I am instructed to grant Mrs. Carstairs the privilege of remaining in her own room until tomorrow morning. We are to take no definite action tonight, unless, of course, you and she decide that it is best for her to accompany me to the—er—to headquarters. It is up to you and Mrs. Carstairs, sir.”

Davenport Carstairs was a strong, virile character. He possessed the arrogance born of power and a confidence in himself that had never been shaken. His home was his stronghold, his wife its treasure. In his serene strength he could not conceive of discredit falling upon either. Instead of faltering, now that the first shock had been weathered, he drew himself up and faced the situation with a courage that excited the wonder and admiration of the man who came with evil tidings.

“Be seated,” said he, indicating a chair. The man sat down. “You may be partially if not entirely ignorant of the nature of these charges. Am I right in assuming that you are not at liberty to discuss them with me?”

“On the contrary, Mr. Carstairs, I have been advised to do nothing until I have talked the matter over with you. I am in possession of all the facts.”

“Is the department content to allow me to pass judgment on my wife?” inquired Carstairs, with a touch of irony. He maintained a calm exterior,—at what cost no one but he will ever know. The secret service man made no response. “In any case, I shall have to ask you to explain everything to me before permitting you to approach my wife.”

The agent, who shall be called Jones, nodded his head, and then leaned forward in his chair.
