As he rode back from the chateau one evening the king met Loys de Boisbourdon, whom he knew to be one of Isabeau's associates. Suddenly suspicious and resolved to know the whole truth, Charles had him arrested and put to the question (_i.e._, tortured). Such horrors were revealed by this unlucky sharer of the queen's pleasures that Charles deemed them not fit for further circulation, and accordingly Loys de Boisbourdon carried his secrets with him into a sack, which was inscribed: _Laissez passer la justice du roi_, "Make way for the justice of the king," and the waters of the Seine covered the sack and the sinner. The mad king's justice, of which we read with a certain joyful sympathy, was not ended, for he sent the queen and the duchess of Bavaria to Blois, and later to Tours, where they were compelled to live under surveillance and in salutary simplicity. The dauphin seized some moneys belonging to Isabeau, who henceforth cherished the most unrelenting hatred for her own son, accusing him of being responsible for her exile. The real grief to her, we may feel sure, was the loss of her money. From this time, we find Isabeau intriguing with the Duke of Burgundy. As Jean was marching upon Paris he came into the neighborhood of Tours. The pious Isabeau was suddenly filled with a desire to hear mass at a particular convent some distance outside the walls. While she was engaged in her devotions the troops of Burgundy, in ambush, surrounded the convent and "captured" Isabeau and her guardians. The queen and her ally, styling themselves governors of France, established a parliament at Amiens, sent out decrees by authority of the "council of the queen and the duke," and fought the dauphin on paper and in the field. When in June, 1418, the Parisians, provoked beyond endurance by the exactions and the arrogance of the Armagnac nobles, massacred every Armagnac that they could find, Isabeau stood too much in awe of these fierce men of the common people to enter Paris. Had she not seen their violence before, merely because she lived in luxury while they starved? She waited for the arrival of Jean de Bourgogne, and the two entered Paris together on July 14th. The dauphin, the sole hope of France, fled before the armies of his mother.
