"'Well, sir, I'll tell you. It's a small matter, and I've mentioned it many a time, both to William Brigmawl and to others; but they talk me down, and say I was mistaken; and Eliza Jane being a silly giggling hussey, can't bear me out in what I say. But I do most solemnly declare that I speak the truth, and am not deceived. When the two gentlemen—which gentlemen they both was to look at—came into our hall, the one that was murdered had his coat buttoned tight across his chest, except one button; and through the space left by that one button I saw the glitter of a gold chain.' "'Well, what then?' "'The other gentleman, Mr. Dunbar, had his coat open as he got out of the carriage, and I saw as plain as ever I saw anything, that he had no gold-chain. But two minutes after he had come into the hall, and while he was ordering dinner, he took and bottoned his coat. Well, sir, when he came in, after visiting the cathedral, his coat was partially unbuttoned and I saw that he wore a gold-chain, and, unless I am very much mistaken, the same gold-chain that I had seen peeping out of the breast of the murdered man. I could almost have sworn to that chain because of the colour of the gold, which was a particular deep yaller. It was only afterwards that these things came back to my mind, and I certainly thought them very strange.' "'Was there anything else?' "'Nothing; except what Brigmawl dropped out one night at supper, some weeks after the inquest, about his having noticed Mr. Dunbar opening his desk while he was waiting for Joseph Wilmot to come home to dinner; and Brigmawl do say, now that it ain't a bit of use, that Mr. Dunbar, do what he would, couldn't find the key of his own desk for ever so long.' "'He was confused, I suppose; and his hands trembled, eh?' asked the detective. "'No, sir; according to what Brigmawl said, Mr. Dunbar seemed as cool and collected as if he was made of iron. But he kept trying first one key and then another, for ever so long, before he could find the right one.' "'Did he now? that was queer.' "'But I hope you won't think anything of what I've let drop, sir,' said the waiter, hastily. 'I'm sure I wouldn't say any thing disrespectful against Mr. Dunbar; but you asked me what I saw, sir, and I have told you candid, and——' "'My good fellow, you're perfectly safe in talking to me,' the detective answered, heartily. 'Suppose you bring us a little strong tea, and clear away this dessert; and if you've anything more to tell us, you can say it while you're pouring out the tea. There's so much connected with these sort of things that never gets into the papers, that really it's quite interesting to hear of 'em from an eye-witness.' "The waiter went away, pleased and re-assured, after clearing the table very slowly. I was impatient to hear what Mr. Carter had gathered from the man's talk. "'Well,' he said, 'unless I'm very much mistaken, I think I've got my friend the master of Maudesley Abbey.'
