The Mayor of Casterbridge

Michael Henchard, an out-of-work hay-trusser, gets drunk at a fair and, for five guineas, sells his wife and child to a sailor. When the horror of his act finally sets in, Henchard swears he will not touch alcohol for twenty-one years. Through hard work and acumen, he becomes rich, respected, and eventually the mayor of Casterbridge. But eighteen years after his fateful oath, his wife and daughter return to Casterbridge, and his fortunes steadily decline.
