"Why, yes—no—that is, once in a while, if I happen to desire an audience at an unusual hour," answered the Secretary, exhibiting the first signs of embarrassment.
"Will you please tell us when you called there last?" asked Inspector Byrnes, furtively glancing up and speaking in a chatty, assuring tone.
The Secretary's face expressed relief.
"Certainly," he answered; "that is easy enough. I attended an informal reception in the Blue Room from three to four yesterday and saw the President alone a minute afterward. That is the last time I saw him." One might almost have fancied at the last sentence that tears arose to the eyes of the cabinet officer; at least there were tears in his voice.
"Just as a matter of formality, Mr. Secretary, will you tell us where you were between twelve and two o'clock this morning?" asked the Inspector, with the unconscious look of a man who was asking for a glass of water.
"What does this mean, sir? Do you suspect me in this infernal mystery?" ejaculated the Secretary. His face was pale from excitement; his eyes flashed in manly protest.
"Not at all, not at all, sir. Calm yourself. This is only a matter of curious coincidence and a disagreeable formality," answered the Inspector, waving his hand as if he were brushing away a fly.
The Secretary stood a moment in thought, and then turned and touched a button. Immediately a servant appeared to whom the Secretary whispered a few words. The man in livery bowed and went.
"Now, gentlemen," said the Secretary, standing with much dignity before his callers, "wait a moment, and so far as I am concerned this mystery shall be cleared. I happened to be in this room last night from twelve until half-past two with some gentlemen, whom I am sure you will recognize. Ah! here they are."
A tap at the door and a "Come in" revealed to the astonished detectives the Secretaries of War and of the Interior, who entered the room.
