The Princess remained in such a state of confusion that it was some time before she came to her senses. Her first thought was to send someone after the Comte to tell him not to bring the Duc, but she could not bring herself to do so. She then thought that failing this, she had only not to have the drawbridge lowered, and she believed that she would continue with this resolve, but when the hour of the assignation drew near she was no longer able to resist the desire to see the lover whom she longed for, and she gave instructions to one of her women on the method by which the Duc was to be introduced into her apartment.
Meanwhile the Duc and the Comte were approaching Champigny, but in very differing frames of mind. The Duc was full of joy and all the happiness of expectation. The Comte was in a mood of despair and anger, which tempted him at times to run his sword through his rival. They at last reached the park, where they left their horses in the care of the Duc's squire, and passing through a gap in the wall they came to the flower garden. The Comte had always retained some hope that the Princess would come to her senses and resolve not to see the Duc, but when he saw that the drawbridge was lowered he realised that his hope was in vain. He was tempted to take some desperate measure, but he was aware that any noise would be heard by the Prince de Montpensier whose rooms looked out onto the same flower-garden, and that all the subsequent disorder would fall on the head of the one he loved most. He calmed himself and led the Duc to the presence of the Princess.
Although the Princess signaled that she would like him to stay in the room during the interview, he was unwilling to do so, and retired to a little passage which ran alongside the Princess's apartment, a prey to the saddest thoughts which could afflict a disappointed lover.
Now, although they had made very little noise while crossing the bridge, the Prince de Montpensier was awake and heard it. He made one of his servants get up and go to see what it was. The servant put his head out of the window and in the darkness he could make out that the drawbridge was lowered. He told his master who then ordered him to go into the park and find out what was going on. Amoment later he got up himself, being disturbed by what he thought he had heard, that is footsteps on the bridge leading to his wife's quarters.
As he was going towards the little passage where the Comte was waiting, the Princess who was somewhat embarrassed at being alone with the Duc de Guise, asked the latter several times to come into the room. He refused to do so and as she continued to press him and as he was furiously angry he answered her so loudly that he was heard by the Prince de Montpensier, but so indistinctly that the Prince heard only a man's voice without being able to recognise it as that of the Comte.
These events would have infuriated a character more placid and less jealous than the Prince de Montpensier. He hurled himself against the door, calling for it to be opened, and cruelly surprising the Princess, the Duc de Guise and the Comte de Chabannes. This last, hearing the Prince's voice, saw immediately that it was impossible to prevent him from believing that there was someone in his wife's room, and that he was in such a state that if he found that it was the Duc de Guise he might kill him before the eyes of the Princess and that even her life might be at risk. He decided, in an act of extraordinary generosity, to sacrifice himself to save a successful rival and an ungrateful mistress.
While the Prince was battering on the door, he went to the Duc, who had no idea what to do, put him in the care of the woman who had arranged his entry by the bridge and told her to show him the way out. Scarcely had he left when the Prince having broken down the door entered the room like a man possessed. However when he saw only the Comte de Chabanne, motionless, leaning on a table with a look of infinite sadness on his face, he stopped short.
The astonishment of finding his best friend alone at night in his wife's room deprived him of speech. The Princess had collapsed onto some cushions and never perhaps has fate put three people in a more unhappy position. At last the Prince made an attempt to make sense of the chaos before his eyes. He addressed the Comte in a tone of voice which still had some friendliness, "What is this I see?" he said. "Is it possible that a man I love so dearly has chosen among all other women to seduce my wife? And you madame," he said, turning to his wife, "was it not enough to deprive me of your love and my honour without depriving me of the one man who could have consoled me in such circumstances? Answer me, one of you," he said to them, "and explain this affair, which I cannot believe is what it seems." The Princess was incapable of replying and the Comte opened his mouth once or twice but was unable to speak.
"You see me as a criminal" he said at last, "and unworthy of the friendship you have shown me; but the situation is not what you may think it is. I am more unhappy than you and more despairing.
