Therese’s attempt to prevent the Comte de Bressac from murdering his aunt, the Marquise de Bressac, turns a secret plot into a test of whether integrity can protect anyone in a world governed by wealth and power. She refuses to poison the Marquise, exposes the scheme, and seeks help for her; the Count intercepts the appeal and punishes Therese. The Marquise dies shortly afterward, and the Count uses her death to cast suspicion on the very person who tried to save her.

Causes and Background

Therese has served the Marquise for four years, enduring continued hardship while remaining attached to the household. The Comte de Bressac has cultivated her trust, and she admits that she once felt affection for him. That intimacy makes his disclosure all the more shocking: believing he can rely on her, he tells her that he has condemned his aunt to die and intends to use Therese to accomplish it.

The Count presents murder as an ordinary matter of nature, arguing that destruction merely changes the forms of matter and cannot truly annihilate life. He also dismisses the added gravity of killing a relative. His reasoning is not an abstract conversation detached from action: it is designed to make Therese an accomplice. She initially resists, but deliberately delays her refusal and appears to yield, allowing the Count to believe that his arguments have overcome her objections.

Therese Warns the Marquise

The Count gives Therese poison and directs her to put it in the Marquise’s morning chocolate. He promises her immunity from consequences and offers a written annuity of two thousand crowns, payable after the deed. His confidence grows when he learns that an uncle has left him a substantial inheritance. Rather than abandon the plan now that his fortunes have improved, he insists that the murder proceed before the household returns to Paris and presses Therese to act quickly.

Therese sees danger whichever way she turns. She fears that if she simply refuses, the Count will suspect her, and that if she consults the law, she may expose herself to his vengeance. She decides instead to warn the Marquise, first requiring her to promise not to confront her nephew openly. To prove the threat, Therese produces the poison; the women test a small quantity on a dog, which dies after convulsions. The Marquise then sends a courier to the Duc de Sonzeval, asking him to approach the Secretary of State secretly, obtain a lettre de cachet, and hurry to protect her from her nephew.

The Appeal Is Intercepted

The Count grows suspicious after noticing the Marquise’s agitation and Therese’s unease. The Marquise gives him a false explanation for the courier’s journey, saying it concerns the newly inherited estate and possible litigation. The Count pretends to accept this account, leaves under the pretext of a walk, and intercepts the messenger on the route he knows the man must take.

The courier, who proves more loyal to the Count than to the Marquise, allows his master to inspect the dispatches. The Count pays him a hundred louis and orders him never to return to the household. With the appeal for help in his possession, the Count goes back and continues to behave as though nothing has changed. He still cajoles Therese and asks whether she will carry out the poisoning, concealing that he has discovered her intervention. Therese, unaware that the message has been intercepted, attends their arranged meeting in the woods.

Retaliation and Accusation

At the meeting, the Count leads Therese toward the four trees where she had previously been bound. There he has prepared a punishment and accuses her of betraying him after agreeing to the crime. He claims that she chose the greater wrong by endangering his freedom, and insists that virtue has brought her only danger. The Count’s response reverses the roles of protector and threat: the man who once spared her now uses his power over her to exact revenge for her attempt to save his aunt.

The Count has Therese bound and sets his mastiffs upon her while he watches. He stops the attack before it kills her, then orders her to dress and leave. He refuses to offer compassion or practical help, although he allows her to keep whatever money she has. He warns that the arrest warrant against her remains in force and that she will be publicly blamed for the Marquise’s murder. Rather than face one case, he tells her, she will now have to contend with a rich and powerful enemy intent on pursuing her.

Therese answers that she will not retaliate against him. She explains that she acted only because the Marquise’s life was at stake and promises to pray for him despite his cruelty. The Count leaves, and she never sees him again. The exchange sharpens the event’s central conflict: his language makes complicity sound like safety, while her refusal to harm an innocent person leaves her exposed to punishment.

The Marquise’s Death and the Aftermath

A local surgeon named Rodin treats Therese and gives her a place to stay. After thirty days, she has recovered enough to make inquiries at the château. She has only six louis with her, while more than forty remain in her room at the Marquise’s residence. Hoping to recover her belongings and earnings, she sends a letter through a young peasant woman named Jeannette, carefully concealing where she is staying.

The news Jeannette brings makes the consequences of Therese’s warning especially stark. The Marquise fell gravely ill on the day Therese left and died the following morning. The Comte de Bressac claimed that a chambermaid who had fled had poisoned her. The household’s relatives gathered, lamented the Marquise, and spoke of avenging her, but the Count retained undisputed possession of his inheritance and the valuables in the Marquise’s strongbox, pocketbook, and jewels—worth more than six hundred thousand francs in addition to his revenues.

The Count’s reply to Therese’s request compounds the accusation. In the letter, he calls her the criminal responsible for his aunt’s death, accuses her of theft, and threatens to have Jeannette detained if she makes another request. Therese is more distressed by the implication that the Marquise was indeed murdered than by the refusal to return her property. The letter confirms that the Count has turned the failure of her rescue into a story in which she is the perpetrator, while he profits from the death she had tried to prevent.

Significance in the Framed Narrative

This episode is part of Therese’s first-person account to Madame de Lorsange and Monsieur de Corville, whom she meets while being transported as a prisoner. The larger story thus presents the plot against the Marquise not only as a past ordeal but as testimony offered by a woman already accused of murder, theft, and arson. The circumstances of her testimony matter: she tells her history to explain how she came to be treated as a criminal, while the listeners have the opportunity to judge her account and respond to it.

The event also establishes a recurring reversal in Therese’s fortunes. She attempts to prevent a killing and instead faces a violent reprisal; the intended victim dies, while the would-be murderer gains wealth and retains power. Yet her account does not end with the Count’s accusation. Madame de Lorsange and Monsieur de Corville listen with profound emotion, and the Countess’s recognition of Therese as her sister ultimately changes the conditions of Therese’s captivity. In the frame narrative, the story of failed protection becomes the testimony that helps make a new intervention possible.
