What if the monster kept a diary?
Consider it. The wicked queen does not scrawl her grievances in fire and brimstone. She writes in a careful hand, late at night, in a room that smells of lavender and old grief. She records the weather. She worries about her posture. And somewhere between the second page and the twentieth, we realize we have been reading the confession of a woman who does not believe she is wicked at all. That is the unsettling heart of the fairy tale villain prompt this week: force yourself to narrate a story you already know as the “evil” one, in a form built entirely to betray its writer. Nothing blinds a reader like a first-person diary. Nothing lies so politely.
What follows is a craft essay and a commission. First, the theory of writing a villainous diary. Then, an original case study to study, steal from, or argue with. Then, the prompt itself, sharpened and waiting for you.
The Anatomy of a Fairy Tale Villain Prompt
Fairy tales are cruel economies. A character is granted one quality — beauty, cruelty, age, appetite — and the whole world narrows to that single trait. The stepmother is jealous. The wolf is hungry. The witch wants a child’s flesh. This compression is the genre’s engine and its great dishonesty. As the folklorist Jack Zipes has argued for decades, these tales encode social contracts: they tell us who must be punished for transgressing, and they rarely ask whether the punishment fits the crime. For a working writer, that compression is an invitation. Somewhere inside that flattened figure is a person who once had a mother, a mortgage, a morning routine.
Your task in this fairy tale villain prompt is not to excuse the monster. It is to restore the dimensions that the tale sanded away — and then to let the reader decide, uneasily, whether the crime now seems smaller, larger, or simply differently shaped.
Why the Diary? The Form Is a Liar by Design
The diary is the most intimate of forms and the least trustworthy. A letter has a recipient who might reply. A confession has an audience that might sentence. But a diary is addressed to no one, which means it is addressed to the self — and the self is an unreliable editor.
Every great unreliable diary exploits the gap between what the writer believes and what the page records. In We Have Always Lived in the Castle, Shirley Jackson’s Merricat Blackwood narrates with the eerie calm of a child who has buried her family and feels only relief. In Lolita, Humbert Humbert performs scholarship to dress his predation as romance. In both cases, the reader becomes a detective of tone. You are not reading what happened. You are reading what a particular mind needed to believe happened. For an excellent survey of that technique, see Literary Hub on the art of the unreliable narrator.
This is precisely why the villain’s diary works where a villain’s monologue fails. A monologue is performed for a victim. A diary is performed for the mirror — and the mirror, as any wicked queen will tell you, is a devastating audience.
The Four Mechanisms of Villainous Self-Deception
To write a compelling antagonist’s diary, arm yourself with four recurring moves. Vary them. Let them contradict one another. Contradiction is character.
1. Self-justification framed as housekeeping. The most chilling diary entries do not defend monstrous acts. They schedule them. “The apple must be prepared before Thursday, or the market will be crowded.” The bureaucracy of evil domesticates it. Poe understood this principle of the mundane grotesque; his killers are always preoccupied with trifles — the heartbeat under the floorboards, the careful arrangement of the stone. Read how his narrator in Poe’s collected works lingers on disposal rather than remorse. The horror lives in the inventory.
2. Projection of the hero’s ugliness. Your villain should accuse the heroine of the villain’s own sins — or of sins she has not yet committed. This is prophecy as poison. The queen in Snow White does not say “she is beautiful and I am vain.” She says, and she believes it, “she is a threat to the realm.” Give your villain a political theory. Give them statistics.
3. Omission by silence. The diary will skip the worst day. It will describe the weather of the day a girl vanished. It will say “I retired early” and never say where the knife went. Trust your reader to fall into these gaps and to fill them with something worse than you could have written. For a deeper dive into withholding, see our earlier essay on writing villains readers fear and mourn.
4. Sudden tenderness toward something small. Let your villain be kind to a dog, a servant, a dying moth. Genuine, unforced tenderness destabilizes the reader far more than any catalogue of crimes. Tana French does this masterfully: even her most compromised figures keep an aching tenderness for a place or a person, and that ache makes judgement impossible. It is a technique worth studying alongside our piece on building gothic atmosphere, where mood must always do more than decorate.
Choosing Your Fairy Tale: A Casting Note
Not every tale rewards the villain’s diary equally. You want a figure who had interior life before the plot arrived — someone with a grievance legible enough to dramatize and a crime specific enough to deny.
Bluebeard is a superb choice: his diary can be all charm, all invitations, all complaint about “the suspicion of women.” The Sea Witch from The Little Mermaid offers moral arithmetic: what was the price, and who set it? The Huntsman in Snow White is even better, because his diary is a single night long — the whole story is one decision in a forest. Meanwhile, avoid villains who are pure abstraction, like the Giant in “Jack and the Beanstalk.” He has no room to breathe.
Common Pitfalls: Where the Diary Dies
The redemption rewrite. If your villain turns out to be secretly noble, brave, and right, you have not written a villain’s diary. You have written an apology. Keep the crime. Let the diary explain it without excusing it.
The modern-psychology lecture. Resist having your witch diagnose herself with trauma in clinical language. The fairy-tale register is the point. Let her use her own vocabulary — curses, debts, contracts, old wounds with old names.
The monotone of menace. A diary that is dark on every page becomes wallpaper. You need Tuesday entries that are boring, comic, domestic. The darkness must be a surprise, not a wallpaper.
The missing clock. Without dates or a sense of elapsed time, a diary collapses into a rant. Give your entries a rhythm: seasons, tides, market days, feast days. Time is the diary’s spine.

The Prompt, Sharpened
Here it is, in full. Choose a classic fairy tale. Choose its villain. Write six to ten diary entries in the villain’s own voice, spanning the weeks before, during, and after the tale’s central crime. In at least one entry, your villain must be demonstrably wrong about a fact the reader knows. In at least one other, your villain must be demonstrably right about something everyone else in the tale refuses to admit. End with an entry that does not resolve — a trailing sentence, a plan abandoned, a mirror covered.
Now, an example of what that commission can yield.
A Case Study: The Sea-Witch’s Ledger
The following is an original short story, written as a sequence of diary entries from the villain of a familiar mermaid’s tale. Note the self-justification, the omissions, the sudden tenderness, and the final unresolved silence.
ENTRY ONE — The Ninth Day of the Long Current.
A girl came to my reef today. Very young. Very certain. She had already decided I was the monster of her grandmother’s parables, and honestly, it saves time when they arrive pre-convinced.
She wanted legs. They always want legs. Legs and the land-prince and the noise above the water, which they call music.
I told her the price. She blinked, and in that blink I saw she had already agreed. One does not negotiate with a girl who has rehearsed her own ruin.
ENTRY TWO — The Eleventh Day of the Long Current.
They will say I took her voice for cruelty. I took her voice because I am not permitted to keep one of my own, and the sea counts its debts in symmetry. My sisters took mine, years ago, when I objected to a certain arrangement. I have not made a sound since. I am told this builds character.
The girl should be flattered. The trade is exact.
ENTRY THREE — The Fourteenth Day of the Long Current.
The pain in her walking was not in the contract. I want that written down somewhere, since I have no one to tell.
I offered her the salve. She refused it with that particular pride of the suffering, which I remember having at her age, and which is the closest thing my kind has to a religion.
So be it. The reef keeps no saints.
ENTRY FOUR — The First Day of the Drowning Season.
The land-prince has married. A princess of a coast I have never troubled. There is a rumour that a mute girl saved him from a wreck, and that no one could learn her name, and that therefore she was, in the ordinary machinery of such stories, quietly replaced by someone with a family.
I did not cause this. I want that noted with particular clarity. I sold her three days and a pair of ankles. The rest was done by men with inventories.
Nevertheless. My name is already written into her story, and I find I resent the authorship more than the accusation.
ENTRY FIVE — The Fourth Day of the Drowning Season.
The knife is for the coral. It is always for the coral. The reef is dying of a heat I did not choose, and I have been cutting the black sections away for eleven years, and if anyone wished to ask me a question at this moment, I should say that the ocean is not a court.
But they will not ask. They will point at the knife and write the ending they require.
ENTRY SIX — The Sixth Day of the Drowning Season.
She has come back. Older by a whole lifetime, which for her species is nothing. She says she is to be dissolved at dawn, and that she did not know the terms, and I said, gently, that she signed them.
She began to cry, and the sound of a girl crying underwater is a thing I would not inflict on my worst enemy, which unfortunately includes my sisters.
I gave her the knife. I have not explained why. Explanation is a land luxury, like shoes.
ENTRY SEVEN — Unnumbered. Before Dawn.
They will say I gave her the knife to destroy a rival. That is a comfortable reading, and the world is fond of comfortable readings.
The truth is a colder water. The knife’s blood falls on land or falls on sea, and either outcome breaks an old contract I have spent my life enforcing and resenting in equal measure. I do not know which way she will choose. I find, to my alarm, that I do not want to.
I have covered the mirror. There is nothing in it I wish to be told about myself tonight.
There is a sound above the reef. It might be a girl’s footsteps. It might be surf. In this house they have always been the same noise.
What to Steal from the Ledger
The first entry performs what we called “pre-convinced victims.” It protects the narrator by conceding her own reputation. That is a classic unreliable move: surrender the small truth to smuggle in the large one.
The second entry is the mechanism of projection and symmetry. The witch reframes theft as trade, and does so with a legalism the reader can both reject and half-understand. Notice that she never denies taking the voice. She only changes its meaning.
The fourth and fifth entries perform omission by displacement. The most important events — a marriage, a coral die-off, an eleven-year penance — are handled at one remove, in the passive voice of rumour and inventory. What the witch will not say is that she is grieving.
The seventh entry refuses resolution, as the prompt demands. The knife has no explained purpose. The witch does not know her own motive. This is the diary’s highest function: to render a consciousness to itself, undecided, and to leave the reader holding the verdict.
After the Writing: How to Test Your Draft
Read your entries aloud. Then ask three questions, in order.
Does the villain believe themselves? If your narrator sounds like they are performing for the reader, you have broken the diary’s sealed privacy. Reduce the adverbs. Add a chore.
Is the hero diminished? The hero must not become a fool, a monster, or a dupe. A villain’s diary that destroys the heroine produces no tension — only smugness. The heroine should remain, at the last, sympathetically human. Then the reader’s discomfort has somewhere to live.
Does the crime survive? If your draft reads as total exoneration, add one entry — a small, precise, damning detail. A receipt. A hesitation. A sentence begun and abandoned. One line of true culpability will do more for your ambiguity than a hundred lines of justification.
Finally, resist the tidy ending. The fairy tale offers closure; your diary must not. Let the last entry trail. Let the mirror be covered. Ambiguity is not indecision — it is generosity toward the reader.
Closing: The Mirror and Its Refusal
Every fairy tale we inherit is a verdict. Someone is fairest, someone is wicked, someone is swallowed, and the swallowings are called justice. The villain’s diary is our one instrument for reopening a closed case — not to acquit, but to complicate, which is the only honest thing fiction can do.
And complication is a mirror of its own. Because when you write your antagonist’s private page, you must sit inside a mind that justifies what you would condemn. You must find its tenderness. You must find its reasoning. And you will discover, in that uncomfortable intimacy, that the distance between your narrator and yourself is shorter than any tale has ever admitted.
So take up the prompt. Choose the villain. Date the page. And when your witch writes the sentence she cannot finish, ask yourself: whose hand is holding the pen — hers, or the one beneath it, the one the tale forgot to name?
