"Just so. Sorry to trouble you, Mr. Simpson, but I must get you to come along o' me on a small matter o' business. You needn't say anything, of course; but if you do I shall have to make a note of it, and it may be used as evidence."

What was this? I gasped, and the whole street seemed to turn round and round and over and over. Arrested! What for?

Whether I asked the question or only moved my lips silently, I don't know, but the man answered—and his voice seemed to come from a distance out of the chaos about me.

"Well, it's about that jewel-case of your aunt's, of course. Sorry to upset you, and no doubt it'll be all right, but just for the present you must come to the station with me. I won't hold you if you promise not to try any games. Or you can have a cab, if you like."

"SORRY TO TROUBLE YOU, MR. SIMPSON."

"But," I said, "but it's all a mistake—an awful mistake! It's—it's out of the question! Come and see my aunt, and she'll tell you! Pray let me see my aunt!"

"Don't mind obliging a gentleman if I can, and if you want to speak to your aunt you may, seein' it's close by, and it ain't a warrant case. But I shall have to be with you, and you'll have to come with me after, whatever she says."

I was in an awful position, and I realized it fully. Here I was with that facsimile brooch in my possession, and if it were found on me at the police-station, of course, it would be taken for the genuine article, and regarded as a positive proof that I was the thief. In the few steps to Aunt Sarah's house I saw and understood now what the police had been at. I was the person they had suspected from the beginning. Their pretence of dropping the inquiry was a mere device to throw me off my ground and lead me to betray myself by my movements. And I had been watched frequenting shady second-hand jewellery shops in Soho! And, no doubt I had been seen in the low eating-house where I might be supposed to be leaving messages for criminal associates! It was hideous. On the one side there was the chance of ruin and imprisonment for theft, and on the other the scarcely less terrible one of estranging Aunt Sarah for ever by confessing my miserable deception. Plainly I had only one way of safety—to brazen out my story of the recovery of the brooch. I was bitterly sorry, now, that I had coloured the story, so far as it had gone, quite so boldly. It had gone a good way, too, for I had been obliged to add something to it each time I saw Aunt Sarah during my operations. But I must lie through stone walls now.
