"The only other evidence there was pointed with all the rest. There were no rain-marks on the leather case; it had been put on the roof as an after-thought when there was no rain. A very poor after-thought, let me tell you, for no thief would throw away a useful case that concealed his booty and protected it from breakage, and throw it away just so as to leave a clue as to what direction he had gone in. I also saw, in the lumber-room, a number of packing-cases--one with a label dated two days back--which had been opened with an iron lever; and yet, when I made an excuse to ask for it, you said there was no such thing in the place. Inference, you didn't want me to compare it with the marks on the desks and doors. That is all, I think." Mr. Claridge looked dolorously down at the floor. "I'm afraid," he said, "that I took an unsuitable rôle when I undertook to rely on my wits to deceive men like you. I thought there wasn't a single vulnerable spot in my defense, but you walk calmly through it at the first attempt. Why did I never think of those raindrops?" "Come," said Hewitt, with a smile, "that sounds unrepentant. I am going, now, to Lord Stanway's. If I were you, I think I should apologize to Mr. Woollett in some way." Lord Stanway, who, in the hour or two of reflection left him after parting with Hewitt, had come to the belief that he had employed a man whose mind was not always in order, received Hewitt's story with natural astonishment. For some time he was in doubt as to whether he would be doing right in acquiescing in anything but a straightforward public statement of the facts connected with the disappearance of the cameo, but in the end was persuaded to let the affair drop, on receiving an assurance from Mr. Woollett that he unreservedly accepted the apology offered him by Mr. Claridge. As for the latter, he was at least sufficiently punished in loss of money and personal humiliation for his escapade. But the bitterest and last blow he sustained when the unblushing Hahn walked smilingly into his office two days later to demand the extra payment agreed on in consideration of the sale. He had been called suddenly away, he exclaimed, on the day he should have come, and hoped his missing the appointment had occasioned no inconvenience. As to the robbery of the cameo, of course he was very sorry, but "pishness was pishness," and he would be glad of a check for the sum agreed on. And the unhappy Claridge was obliged to pay it, knowing that the man had swindled him, but unable to open his mouth to say so. The reward remained on offer for a long time; indeed, it was never publicly withdrawn, I believe, even at the time of Claridge's death. And several intelligent newspapers enlarged upon the fact that an ordinary burglar had completely baffled and defeated the boasted acumen of Mr. Martin Hewitt, the well-known private detective. VII.
