At mid-day I had an appointment with the Home Secretary. He received me with the utmost kindness, and we had half an hour of highly confidential talk. The purport of it will appear later. This is not the place for it. Towards the end I informed him that I had a request to make. "Tell me," he answered at once, "and let me repeat that the Government has every confidence in you, Sir John. Don't take this too hardly, I beg of you." I had a sudden impulse. "I trust," I said, "that my anxiety for the public welfare is in no degree overshadowed by a private sorrow. Indeed, I am sure that it isn't. But, if I may speak in confidence, I should like you to know, sir, that I was engaged to be married to Miss Constance Shepherd." There was a perceptible silence. I heard the great man take a long inward breath, and murmur to himself, "Poor fellow!" Then he did the right, the quite perfect thing: he stretched out his hand, and took mine in a firm, warm grasp. When I could speak, I returned to business. "My request, sir, is this. I want to disappear for a month." "Disappear, Sir John?" "That's what it amounts to. Practically, I am going to ask for four weeks' leave of absence. It must be private, though. If the news were published the public would misunderstand, and think I was deserting my post in a time of difficulty and danger." "Whereas?" "Whereas I want to investigate this affair in my own way. I believe that the theories of the Press and public, and also those of Scotland Yard--with whom I have been in consultation--are quite wrong. Nor do my communications with America give me any reason to change my opinion. This is a matter of life and death to me. I owe the Government, who have promoted me so rapidly to the high position I occupy, a solution of this mystery. I owe them and the public that the fiends who have committed these outrages should be brought to justice. And, if God allows me, I will do it. My honour and that of my department are at stake. Those two things come before anything else. In addition, I have the private reasons of which I have told you. And, in order to succeed, I am persuaded that my way is the only way." "You have certainly the strongest motives a man well could have to urge you on. But can you be a little more explicit?" "I want to leave Mr. Muir Lockhart in charge at the office. He is perfectly capable of taking charge. He has everything at his fingers' ends. And I shall arrange that he can always communicate with me at any time." The Home Secretary thought for a moment, and drummed with his fingers on the arm of his chair. He had been a famous barrister, and renowned for the perfection of his turn-out. His finger-nails were pink and polished as the light fell upon them, and I wondered if he had them manicured. Then he looked up. "Very well, do as you like," he said suddenly. "I take it that you know what you're about. And heartfelt good wishes for your success."
