She had inherited the clock from her grandmother, who had told her that she had received it as a wedding gift and that the clock probably dated from the 19th century. When the antique dealer arrives to pay and take possession of the clock, he takes a closer look and realises that the clock dates from the mid-20th century. He provides proof that this is indeed the case. Marsha apologises that she had given the wrong information. The antique dealer explains that he is not able to buy the clock for 2,750, but that he would be willing to buy the clock for 500.
