"It is, perhaps, as well that you did not," asserted one of the others, "for in that case we might have lost you too. Surely my Lord," he continued, addressing the Prime Minister, "the Police Authorities should be able to obtain some clue respecting his disappearance? Deserted as the passage usually is at that hour of the night, for I have passed through it myself, there _must_ have been some one in the main thoroughfares at either end who would have given the alarm had they noticed anything out of the common." "It is not altogether certain that the crime, if crime it is--and of that we have as yet no evidence--was perpetrated in the passage of which you speak," said the Prime Minister; "but wherever, or however, the deed was committed, the Police I am sure will do their utmost to unravel the mystery. The mere fact that General Woller's disappearance has not yet been accounted for is giving rise to a vast amount of uneasiness. That the same fate should have befallen Mr Castellan will not be likely to add to the public peace of mind. I am sure the Secretary of State for the Home Department will do all that lies in his power to see that no time is lost in bringing the offenders to justice." When the meeting broke up I made my way with all haste to Carlton House Terrace, in order to assure my friend's wife of my sympathy, and to help her in any way that lay in my power. Prostrated with grief though she was, she consented to see me, and I was accordingly admitted to her presence. "Oh, Sir George!" she cried, hastening forward to greet me, "is it possible that you bring news of him? Ah! I can see you do not." She threw herself into a chair with a little cry of despair, and for a moment I scarcely knew what to say to comfort her. "We must hope for the best, Mrs Castellan," I said at last, and then added with an assurance that my heart was far from sharing--"no one knows what the next few hours may bring forth." "But where can he be?" she cried--"and who can have been base enough to harm him? I know that he has enemies, as every man who has made a great name for himself must have, but I cannot think of one who would go so far as to rob me of him. Oh! it is too cruel! too cruel!" We were still talking when news reached us that two members of the Police Department had arrived, and were anxious for an interview. "I cannot see them," the poor lady declared. "I can tell them nothing that they do not know!" "Then let me see them for you," I said. "I think I can answer any questions they may ask, and at the same time it will spare you the pain such an interview would entail." "God bless you for your kindness! You are a true friend." I thereupon left her, and followed my colleague's secretary along the hall in the direction of the study. "This is a sad affair indeed, Mr Gedge," I said, after we had left the morning-room. "I presume you have never heard Mr Castellan say anything as to his being shadowed by any one?"
