Isadora Goode: Mentor, Grand Mistress, and Martyr of the Resistance

Overview

Isadora Goode is the Grand Mistress of the Royal Academy of Witches and the mentor of the protagonist, Lydia Polk. A shrewd, strategic, and morally complex leader, Isadora breaks centuries of isolation by secretly pledging the academy’s aid to Winston Churchill in 1940. Her vision sets in motion the events of A Resistance of Witches, but her willingness to operate outside the high council’s approval ultimately costs her life. In October 1943, during a full‑moon ritual, she is assassinated by a Nazi witch disguised as Kitty Fraser—a betrayal that underscores the novel’s central themes of trust, sacrifice, and the blurred line between magic and morality.

Plot Role

Isadora appears primarily in the first three chapters and is remembered throughout the rest of the novel.

• Chapter One (November 1940): Isadora takes her sixteen‑year‑old apprentice Lydia to a secret meeting with Churchill at 10 Downing Street. Using a magical card to gain entry, she offers the witches of Britain to the war effort. Lydia projects her consciousness to eavesdrop; afterward, Isadora reveals she allowed this observation deliberately. Isadora admits she went behind the high council’s back, believing the witches must act or face doom. She tells Lydia she was chosen as apprentice not for charm but for “stubborn honesty”—a quality that will be needed for what lies ahead.
• Chapter Two (October 1943): Isadora briefs Lydia on the Grimorium Bellum, a devastating grimoire that the Nazis are hunting. She explains that the council has lost its appetite for the war, that the Nazis have been recruiting young magical women, and that the winter solstice is only ten weeks away. She tasks Lydia with locating the book before the Nazis do.
• Chapter Three: During the Samhain full‑moon ritual, Lydia attempts to track the grimoire through the mind of her friend Kitty Fraser. Instead of peaceful memories, she senses hunger, cold, and terror. Opening her eyes, she sees “Kitty” draw a dagger and slash Isadora’s throat.
• Chapter Four: The assassin (a Nazi witch glamoured as Kitty) flees after stealing a fragment of the Grimorium Bellum. Lydia finds the real Kitty also murdered. The academy elders focus on cover‑ups and nominate Lydia as Isadora’s successor, but Lydia denounces their cowardice and leaves.

Isadora’s death haunts Lydia for the rest of the narrative. Her choices—the secret alliance, the trust in her apprentice, the refusal to bow to the council—become the ethical cornerstone against which Lydia measures her own decisions.

Motivations and Traits Shown Through Actions

Isadora’s motivations are revealed chiefly through dialogue and her clandestine actions.

• Patriotism and Pragmatism: In Chapter One, she tells Churchill, “Without us you will lose, and then we are all doomed.” She has seen the devastation of the Blitz and knows that the council’s policy of non‑intervention will lead to catastrophe. She acts without permission because she believes the stakes are too high for bureaucratic delay.
• Strategic Foresight: Isadora selects Lydia as her apprentice precisely because Lydia is “hardheaded, and honest to a fault”—qualities that would be required for the difficult path ahead. This is not a sentimental choice; it is a calculated one. She knows that a diplomat would fold under pressure, while someone like Lydia will “see it through to the end, even if it costs you dearly.”
• Secrecy and Control: Isadora reveals her true age and face to Lydia only after the Churchill meeting, showing that she trusts her apprentice with intimate vulnerability. Yet she also keeps many plans hidden, such as the Grimorium Bellum mission, until the last moment.
• Willingness to Sacrifice: By pledging the academy without the high council’s consent, Isadora knowingly makes herself a target. The novel strongly implies that this act of defiance created enemies who either collaborated with the Nazi plot or failed to protect her. Her readiness to sacrifice her own safety for a chance at victory is her defining trait.

Interpretation alert: The text does not explicitly state that Isadora foresaw her own death, but her comment to Lydia in the car—“I would wonder if perhaps Isadora had known every terrible thing that would come to pass, right from the beginning”—is Lydia’s retrospective interpretation. The narrator does not confirm whether Isadora had prophetic abilities; it remains an open question.

Chronological Arc

Isadora’s arc is a rising curve of influence followed by a sudden, violent fall. She never lives to see the outcome of her gamble. Her death is the catalyst for Lydia’s journey from obedient apprentice to defiant leader.

Relationships

• Lydia Polk (Apprentice): Isadora is a stern but deeply invested mentor. She tests Lydia, trusts her with the most sensitive secrets, and ultimately passes her own mantle—not through ceremony, but through the example of her sacrifice. After Isadora’s death, Lydia is pushed into a leadership role she did not want.
• Sybil Winter (Old Friend): Sybil is one of Isadora’s few confidantes. They came up through the academy together. Sybil later becomes a complex antagonist; she tries to persuade Lydia to join a coven that controls the Grimorium Bellum, and Lydia feels a “terrible sorrow” at losing Sybil’s trust. The betrayal that Sybil represents is a shadow of the one that killed Isadora.
• The High Council: Isadora views the council as timid and self‑interested. She bypasses them on the Churchill alliance, and their subsequent inaction (focusing on cover‑ups rather than justice) fuels Lydia’s disgust. The conflict between Isadora and the council mirrors the theme of power and corruption.
• The Assassin (Nazi Witch / False Kitty Fraser): The murderer exploits Isadora’s trust. The disguise itself is a visceral symbol of betrayal—the one who kills Isadora wears the face of her apprentice’s best friend.

Key Decisions and Consequences

1. Pledging the academy to Churchill (Nov 1940): This decision breaks centuries of tradition and directly leads to the Nazi targeting of the academy. It also puts Isadora at odds with the high council.
2. Choosing Lydia as apprentice: Isadora’s choice ensures that after her death, someone with stubborn honesty—not diplomacy—will carry on the fight. Lydia eventually refuses the high council’s seat and goes after the Grimorium Bellum alone, a decision Isadora might have approved.
3. Launching Project Diana: The covert operation to retrieve magical objects before the Nazis finds them. It gives Lydia a purpose but also exposes her to danger. The failure of the agent at Château de Laurier (who only escaped with a torn page fragment) sets the stage for the Samhain ritual.
4. Not sharing her full knowledge of the assassin threat: Isadora told Lydia that the Nazis were recruiting young magical women, but she did not reveal that a spy might be inside the academy. Whether she knew of Kitty’s duplication is left ambiguous. This omission leads directly to her death.

Theme and Symbol Connections

• Betrayal: Isadora is murdered by a woman wearing the face of a friend. The theme of betrayal runs through the council’s failure to protect her and Sybil’s later manipulation of Lydia.
• Sacrifice: Isadora gives her life for a cause she knows may fail. Her last words are never shown, but her entire arc is a study of willing self‑sacrifice.
• Magic vs. Morality: Isadora uses magic to break secrecy and to wield influence over Churchill. The Grimorium Bellum represents the ultimate test of whether magic should be used for destruction, even in a just war.
• Power and Corruption: Isadora accumulates power by bypassing democratic structures (the high council). While she uses this power for what she deems good, her unilateralism leaves her vulnerable. The novel asks whether any witch—even a well‑intentioned one—should hold unchecked authority.
• Resistance and Resilience: Isadora’s defiance of the council and the Nazis embodies resistance. Her legacy inspires Lydia to continue the fight even after death.

Five Book‑Specific Questions and Answers

1. Why did Isadora choose Lydia as her apprentice instead of a more diplomatic student?
Isadora explicitly states that Lydia was chosen for her “stubborn honesty” and refusal to bow to authority. She tells Lydia that charm and manipulation were never what would be required for the coming crisis—only determination would matter (Chapter One).

2. Did Isadora know that a Nazi spy was inside the academy?
The novel does not provide a direct answer. Isadora warned Lydia that the Nazis were recruiting young witches, but she did not name a specific infiltrator. Lydia later suspects that Speaker Vivian may have left a door in the warding (Chapter Eight), but whether Isadora knew more than she said remains ambiguous. This is left as an interpretable gap.

3. How did Isadora’s death change Lydia’s path in the novel?
Lydia was already a loyal apprentice, but Isadora’s murder forces her to reject the council’s cowardice and pursue justice on her own terms. She refuses the position of Grand Mistress, leaves the academy, and ultimately takes on the coven that controls the Grimorium Bellum—a mission Isadora herself could not finish.

4. What was Isadora’s relationship with Sybil Winter?
They were lifelong friends who came up through the academy together. Sybil taught projection and showed maternal warmth to Lydia. However, after Isadora’s death, Sybil attempts to recruit Lydia into a coven that seeks to use the Grimorium Bellum, revealing that their shared values had frayed. In Chapter Thirty, Lydia reflects that she has “lost not just Isadora and Kitty, but Sybil too.”

5. What is Isadora’s ultimate legacy in the story?
Isadora is remembered as the woman who broke the witches’ isolation to fight the Nazis. Her secret alliance with Churchill, her faith in an honest apprentice, and her violent death become the moral foundation of Lydia’s quest. The novel ends on VE Day in 1945, with Lydia continuing hunt for former Nazis, suggesting that Isadora’s gamble—though it cost her life—helped secure a chance for victory.
