I obeyed without a word, and with the less uneasiness as I had time to consider the situation. It even struck me that Raffles was for once inclined to exaggerate the undeniable risk that we ran by remaining in the same room with an officer whom both he and I knew only too well by name and repute. Raffles, after all, had aged and altered out of knowledge; but he had not lost the nerve that was equal to a far more direct encounter than was at all likely to be forced upon us. On the other hand, it was most improbable that a distinguished detective would know by sight an obscure delinquent like myself; besides, this one had come to the front since my day. Yet a risk it was, and I certainly did not smile as I bent over the album of horrors produced by our guide. I could still take an interest in the dreadful photographs of murderous and murdered men; they appealed to the morbid element in my nature; and it was doubtless with degenerate unction that I called Raffles's attention to a certain scene of notorious slaughter. There was no response. I looked round. There was no Raffles to respond. We had all three been examining the photographs at one of the windows; at another three newcomers were similarly engrossed; and without one word, or a single sound, Raffles had decamped behind all our backs. Fortunately the clerk was himself very busy gloating over the horrors of the album; before he looked round I had hidden my astonishment, but not my wrath, of which I had the instinctive sense to make no secret. "My friend's the most impatient man on earth!" I exclaimed. "He said he was going to catch a train, and now he's gone without a word!" "I never heard him," said the clerk, looking puzzled. "No more did I; but he did touch me on the shoulder," I lied, "and say something or other. I was too deep in this beastly book to pay much attention. He must have meant that he was off. Well, let him be off! I mean to see all that's to be seen."
