Red Eve by H. Rider Haggard

About noon of the day on which Hugh and his company had ridden for London, another company entered Dunwich -- namely, Sir John Clavering and many of his folk, though with him were neither Sir Edmund Acour nor any of his French train. Sir John's temper had never been of the best, for he was a man who, whatever his prosperity, found life hard and made it harder for all those about him. But seldom had he been angrier than he was this day, when his rage was mingled with real sorrow for the loss of his only son, slain in a fight brought about by the daughter of one of them and the sister of the other and urged for honour's sake by himself, the father of them both.

Moreover, the marriage on which he had set his heart between Eve and the glittering French lord whose future seemed so great had been brought to naught, and this turbulent, hot-hearted Eve had fled into sanctuary. Her lover, too, the youngest son of a merchant, had ridden away to London, doubtless upon some mission which boded no good to him or his, leaving a blood feud behind him between the wealthy de Cressis and all the Clavering kin.
