I had intended going into the country that afternoon, but, in the light of this new calamity, I changed my mind and resolved to remain in Town. Accordingly, after lunch I drove to my office, and remained there until towards evening. By three o'clock, as I have already said, the terrible intelligence was known all over the town. In all my experience I cannot remember a scene of greater excitement. Downing Street, in particular, was filled with an enormous crowd, eager to learn the latest news. In the public mind Castellan's disappearance figured as the work of an enemy, very probably by reason of the prominent part he had played in the history and development of the war. The wildest rumours were afloat concerning the affair, and every edition of the evening papers contained some new item connected with it. At four o'clock I bade my secretary telephone to Scotland Yard and enquire whether they had any information to impart. The reply was to the effect that their labours had so far been entirely fruitless. As in poor Woller's case, not a trace of the missing man could be discovered. Castellan could not have vanished more completely had he been caught up to the sky at the very moment that I had said "good-bye" to him. "It is really most uncomfortable for every one concerned," my secretary remarked. "If this sort of thing is to continue, one does not know who the next victim may be." He was quite right; one certainly _did not_ know. This much, however, was quite certain: whoever the persons might be who perpetrated the crime, they were past masters of their art. Their arrangements and the general conduct of the affair was perfection itself, and against such science it was almost impossible to guard. For my own part--and I don't think my worst enemies can accuse me of cowardice--I must confess to a distinct feeling of uneasiness when I reflected that this mysterious individual, or band, might possibly try his, or their, hand upon me. The suggestion emanating from Scotland Yard to the effect that we should avail ourselves of the offer of police protection, I politely, but firmly declined. The idea of being shadowed night and day by detectives was more than distasteful to me. "Yet we do not desire to lose you, Sir George," said the Prime Minister later, and in saying it he was kind enough to pay me a compliment which my modesty will not permit me to repeat here. I owe him an apology in this matter, however, for I now see that he was right. If I should have to go through it all again, however, I feel that I should act as I did then.
