My officers have worked very hard, and the matter served as a good excuse for giving them a little dinner." For the next day or two everything passed off quietly, but four of the officers reported that when dining at a cabaret two or three of the duke's officers had come in and entered into conversation with them, and had brought up the subject of their riding in after the cardinal.
"You almost looked as if you were serving as a bodyguard to him," one of them laughed.
"I daresay we did," was the answer.

"It was rather a nuisance; but it would not have been courteous to have ridden past the carriage." And he then repeated the story as had been arranged.
Although the Duke of Beaufort had been told by some of his friends that there were rumours abroad of a plot against Mazarin's life, and that it would be best for him to leave Paris for a time, he refused to do so, saying that even if it was discovered the cardinal would not dare to lay hands on him.

Moreover, the replies which had been obtained from Hector and his officers convinced him that their riding behind Mazarin's carriage was an accident.
On the 2nd of September the duke presented himself at the Louvre as usual.

After speaking with him for a few minutes, the queen left the room with Mazarin, and Guibaut, captain of the Guards, at once came forward and arrested him.

He was kept at the Louvre that night, and next day was taken to the castle of Vincennes.
