No one knows how the quarrel between Peter Joyce and Patrick Joseph Flanagan began. It had been smouldering for years, a steady-going feud, before it reached its crisis last June. The Joyces and Flanagans were neighbours, occupying farms of very poor land on the side of Letterbrack, a damp and lonely hill some miles from the nearest market town. This fact explains the persistence of the feud. It is not easy to keep up a quarrel with a man whom you only see once a month or so. Nor is it possible to concentrate the mind on one particular enemy if you live in a crowded place. Joyce and Flanagan saw each other every day. They could not help seeing each other, for their farms were small. They scarcely ever saw anyone else, because there were no other farms on the side of the hill. And the feud was a family affair. Mrs. Joyce and Mrs. Flanagan disliked each other heartily and never met without using language calculated to embitter the feeling between them. The young Joyces and the young Flanagans fought fiercely on their way to and from school. The war, which has turned Europe upside down and dragged most things from their familiar moorings, had its effect on the lives of the two farmers on the side of Letterbrack. They became better off than they had ever been before. It must not be supposed that they grew rich. According to the standard of English working men they had always been wretchedly poor. All that the war did for them was to put a little, a very little, more money into their pockets. They themselves did not connect their new prosperity with the war. They did not, indeed, think about the war at all, bring fully occupied with their work and their private quarrel. They noticed, without inquiring into causes, that the prices of the things they sold went up steadily. A lean bullock fetched an amazing sum at a fair. Young pigs proved unexpectedly profitable. The eggs which the women carried into town on market days could be exchanged for unusual quantities of tea. And the rise in prices was almost pure gain to these farmers. They lived for the most part on the produce of their own land and bought very little in shops. There came a time when Peter Joyce had a comfortable sum, about £20 in all, laid by after making provision for his rent and taxes. He felt entitled to some little indulgence.
