"I imagined more relics inside. Hadn't he some dodge of getting in and out without opening the lid?" "Of putting his head out, you mean," returned the clerk, whose knowledge of Raffles and his Relics was really most comprehensive on the whole. He moved some of the minor memorials and with his penknife raised the trap-door in the lid. "Only a skylight," remarked Raffles, deliciously unimpressed. "Why, what else did you expect?" asked the clerk, letting the trap-door down again, and looking sorry that he had taken so much trouble. "A backdoor, at least!" replied Raffles, with such a sly look at me that I had to turn aside to smile. It was the last time I smiled that day. The door had opened as I turned, and an unmistakable detective had entered with two more sight-seers like ourselves. He wore the hard, round hat and the dark, thick overcoat which one knows at a glance as the uniform of his grade; and for one awful moment his steely eye was upon us in a flash of cold inquiry. Then the clerk emerged from the recess devoted to the Raffles Relics, and the alarming interloper conducted his party to the window opposite the door. "Inspector Druce," the clerk informed us in impressive whispers, "who had the Chalk Farm case in hand. _He'd_ be the man for Raffles, if Raffles was alive to-day!" "I'm sure he would," was the grave reply. "I should be very sorry to have a man like that after _me_. But what a run there seems to be upon your Black Museum!" "There isn't reelly, sir," whispered the clerk. "We sometimes go weeks on end without having regular visitors like you two gentlemen. I think those are friends of the Inspector's, come to see the Chalk Farm photographs, that helped to hang his man. We've a lot of interesting photographs, sir, if you like to have a look at them." "If it won't take long," said Raffles, taking out his watch; and as the clerk left our side for an instant he gripped my arm. "This is a bit too hot," he whispered, "but we mustn't cut and run like rabbits. That might be fatal. Hide your face in the photographs, and leave everything to me. I'll have a train to catch as soon as ever I dare."
