And he made merrier over his loss than any of us could have imagined the minute before; but the reason dawned on me a little later, when we all trooped down-stairs, leaving the police in possession of the theatre of crime. Lord Thornaby linked arms with Raffles as he led the way. His step was lighter, his gayety no longer sardonic; his very looks had improved. And I divined the load that had been lifted from the hospitable heart of our host. "I only wish," said he, "that this brought us any nearer to the identity of the gentleman we were discussing at dinner, for, of course, we owe it to all our instincts to assume that it was he." "I wonder!" said old Raffles, with a foolhardy glance at me. "But I'm sure of it, my dear sir," cried my lord. "The audacity is his and his alone. I look no further than the fact of his honoring me on the one night of the year when I endeavor to entertain my brother Criminologists. That's no coincidence, sir, but a deliberate irony, which would have occurred to no other criminal mind in England." "You may be right," Raffles had the sense to say this time, though I flattered myself it was my face that made him. "What is still more certain," resumed our host, "is that no other criminal in the world would have crowned so delicious a conception with so perfect an achievement. I feel sure the inspector will agree with us." The policeman in command had knocked and been admitted to the library as Lord Thornaby spoke. "I didn't hear what you said, my lord." "Merely that the perpetrator of this amusing outrage can be no other than the swell mobsman who relieved Lady Melrose of her necklace and poor Danby of half his stock a year or two ago." "I believe your lordship has hit the nail on the head." "The man who took the Thimblely diamonds and returned them to Lord Thimblely, you know." "Perhaps he'll treat your lordship the same." "Not he! I don't mean to cry over _my_ spilt milk. I only wish the fellow joy of all he had time to take. Anything fresh upstairs by the way?" "Yes, my lord: the robbery took place between a quarter past eight and the half-hour." "How on earth do you know?" "The clock that was tied up in the towel had stopped at twenty past." "Have you interviewed my man?" "I have, my lord. He was in your lordship's room until close on the quarter, and all was as it should be when he left it." "Then do you suppose the burglar was in hiding in the house?" "It's impossible to say, my lord. He's not in the house now, for he could only be in your lordship's bedroom or dressing-room, and we have searched every inch of both." Lord Thornaby turned to us when the inspector had retreated, caressing his peaked cap. "I told him to clear up these points first," he explained, jerking his head toward the door. "I had reason to think my man had been neglecting his duties up there. I am glad to find myself mistaken."
