Read it through once

Two days after the mare was back again at thirteen to one taken and offered; she went back even as far as eighteen to one, and then returned for a while to twelve to one. This fluctuation meant that something was wrong, and William began to lose hope. But on the following day the mare was backed to win a good deal of money at Tattersall's, and once more she stood at ten to one. Seeing her back at the old price made William look so hopeful that a patient stopped as he passed down the corridor, and catching sight of the _Sportsman_ on William's lap, he asked him if he was interested in racing. William told him that he was, and that if Chasuble won he would be able to go to Egypt.
