"When I told him I didn't think he could buy it he merely laughed in a very shrewd sort of way and said that money was no object to him, that he had bought rugs costing as much as two thousand dollars and turned them over at a profit. So I asked him to come into the house and the moment he saw the rug he admired it very much. He asked me how much I wanted for it, so I told him I wanted nine hundred dollars. Of course, I didn't expect to get that much, because that is all the rug cost, but these fellows always haggle over price, so it's best to name a good stiff figure right at the start." The Hardy boys smiled at this evidence of their mother's shrewdness. "He said he wouldn't give me nine hundred dollars but he offered seven hundred dollars. I told him that his price was ridiculous, but asked if he had any rugs he wanted to trade for it. He looked rather dubious when I mentioned a trade, and said that while he carried some medium priced rugs with him he carried nothing that could equal the one I wished to sell." "Did he say where he kept these other rugs?" Frank asked. "He said they were at his hotel but that his more valuable rugs were all in the city and that it would take a day or so before he could have them sent here. However, he said that he would buy the rug from me for eight hundred dollars and take a chance on being able to sell me a good rug when he should have them sent down from the city." "Fair enough," remarked Joe. "It seemed fair enough to me, for of course the rug was worth only about eight hundred dollars, perhaps less, because it has been used for several months. I was under no obligation to buy a new rug from him unless I wished, so I accepted his offer and he paid me the money." "Eight hundred dollars!" "In cash. He seemed to carry a great deal of money in a heavy leather wallet. He gave me the money in fifties and fives, and I thought very well of myself for making such a good bargain." "Until you came to bank the money," Frank said. "Until I came to bank the money. The cashier glanced at the bills, then told me he was sorry, but that he couldn't accept them. For a moment I didn't understand him, because I had forgotten all about this scare about counterfeit money and hadn't given the matter a thought. Then he told me that the bills were counterfeit. So there was nothing left for me to do but come back home, realizing that I had been very neatly tricked." "But perhaps you haven't been tricked after all," suggested Frank. "It may be possible that the rug buyer didn't realize the money was bad. Did he say what hotel he was staying at?" "Yes, he told me, but I called up the police and asked them to find him for me. They investigated and found that there had been no rug buyer staying at that hotel all week, nor at any other hotel in Bayport, so far as they could find." "That doesn't look so good."
