When this John d'Juy was returned from Piedmont to Brussels with the poison, he demanded payment as had been agreed on; but Coustain not only refused to give him the money but abused him, in most coarse language,--for this Coustain had not his equal in pride and wickedness. John d'Juy, discontented at such treatment, made his complaints to another gentleman of Burgundy, called Arquembart, and discovered to him the plot. Arquembart, much alarmed, advised him to reveal the whole of it to the count de Charolois, saying, that if he did not instantly do so, he would go and tell it himself. John d'Juy, without further delay, waited on the count, and, casting himself on his knees, humbly besought him to pardon the wickedness he was about to reveal to him, and then told him the whole truth of the intentions of John Coustain. The count was much astonished and troubled, and, hastening to his father the duke, told him all he had just heard, and demanded justice on John Coustain for his disloyalty and treason. The duke said, he should have instant justice,--on which the count returned to his apartments, and ordered John d'Juy to go and surrender himself a prisoner at Rupelmonde, and wait for him there, as he would speedily follow him. On the morrow, which was the feast of St James, as I have said, as the duke was ordering the lord d'Auxi and Philip de Crevecoeur to carry John Coustain prisoner to Rupelmonde, he was playing and amusing himself in the duke's park: the duke called to him, and said that he wished he would go to Rupelmonde, with the lord d'Auxi, to answer a gentleman who had made heavy charges against his honour. Coustain answered insolently, according to his custom, that he did not fear any man on earth, and went to boot himself, and mount a fine horse, attended by four others. In this state, he went to the hôtel of the lord d'Auxi, whom he found mounted, together with Philip de Crevecoeur, and fifteen or sixteen of the duke's archers. When Coustain saw so many archers, he began to fear the consequences: nevertheless, they all rode together through the town of Brussels,--but when they came into the open country, the lord d'Auxi made John Coustain dismount from His war-horse, and mount a small hackney that he rode, which alarmed Coustain more than before; and instantly the lord d'Auxi put his hand on his shoulder, and declared him prisoner to the duke, and then pushed forward, without any stopping, until they came to Rupelmonde. They were scarcely arrived before the count de Charolois came, and took possession of the tower in which John Coustain was confined.
