"Hold thy wheedling tongue, hussy. This trinket--gold you say?" "Try it, you know better than I." Dr. Mountchance took the brooch into the inner room, weighed it, tested the metal and returned to the shop. "I can give you no more than the simple value of the gold. 'Tis not pure--a crown should content ye." "Well, it doesn't. Do you take me for a cutpurse? I'm not that sort." "How do I know? You use thieves' jargon. Where did you pick it up?" Lavinia gave one of her rippling laughs. "That's my business and not yours. I tell you it's honestly come by and I want a guinea for it. You know it's worth five and maybe more. The man who gave it me--I don't care for him you may like to know--isn't mean. He'd spend a fortune on me if I'd care to take it but I don't." She tossed her head disdainfully. "Oh, 'tis from your gallant. Aye, men are easily fooled by bright eyes. Well--well----" Lavinia's ingenuous story had its effect. Not a few of Dr. Mountchance's lady customers preferred money to trinkets and he did a profitable trade in buying these presents at his own price. Some of these flighty damsels were haughty and patronising and others were familiar and impudent. The old man disliked both varieties. Lavinia belonged to neither the first nor the second. She was thoroughly natural and the humour lurking in her sparkling eyes was a weapon which few could resist. Dr. Mountchance unclasped a leather pouch and extracted a guinea. "You've a mighty coaxing tongue, you baggage. Keep it to yourself that I gave you what you asked, lest my reputation as a fair dealing man be gone for ever." "Oh, you may trust me to keep my mouth shut," said Lavinia with mock gravity. A sweeping curtsey and she turned towards the door. At the same moment a lady cloaked and hooded like herself entered. They stared at each other as they passed. Lavinia recognised Sally Salisbury, though the latter was much more finely dressed than when they encountered each other outside the Maidenhead Tavern in St. Giles. Sally was not so sure about Lavinia. The slim girl was now a woman. She carried herself with an air. She had exchanged her shabby garments for clothes of a fashionable cut which she knew how to wear. Still, some chord in Sally's memory was stirred and she advanced into the shop with a puzzled look on her face. Mountchance received his fresh customer obsequiously. He had made a good deal of money out of Sally; she never brought him anything which was not valuable and worth buying. Sometimes her treasures were presents from admirers, sometimes they were the proceeds of highway robberies. The latter yielded the most profit. The would-be sellers dared not haggle. They were only too anxious to get rid of their ill-gotten gains. The old man bowed Sally Salisbury into his inner room. He knew that the business which had brought her to him was one that meant privacy. He ceremoniously placed a chair for her and awaited her pleasure.
