Barry, an auctioneer, was holding an auction on a Saturday morning. At the beginning of the auction, Barry announced that the auction was being held without reserve. Helen, Mary, and Chris were all in attendance. Helen saw an old cash register with a stuck drawer that she thought would look great in her den. The auctioneer put the cash register up for sale noting that the drawer was stuck but that it could probably be fixed with little effort. Helen bought it for $20. When she got it home, she discovered that it actually contained $5,000. Unfortunately, Helen had a teenage son named Tad who started bragging to his friends about the family's good fortune. Barry heard about what had happened and sued Helen for return of the $5,000. At the same auction, Mary saw a great deal on a used table. She bid $20 on it. No one else bid anything. Barry announced that $20 was clearly insufficient for the table, that it was worth much more than that, and that he was taking it out of the auction. Chris started bidding on a diamond ring for his girlfriend. He bid $2,000. Just as Barry was getting ready to say "Sold", Chris looked over at his girlfriend, decided that he was not sure about marriage, and leaped up yelling "I revoke." Barry, however, immediately after, yelled "Sold." Barry sues Chris attempting to obtain the money for the engagement ring. Barry also sues Helen seeking to recover the $5,000 contained in the stuck drawer. Mary sues Barry attempting to obtain possession of the table. In the lawsuit in which Barry sues Helen for return of the $5,000, which of the following is the most likely result?
