# The Last Séance

**Read aloud (cold open, beat 1):** London, November 1893, and the fog has swallowed Graycliff Place. You came to Madame Garnet's séance as a sceptic, asked by Rosamund Coldwell to expose her, and sat in the dark circle between Rosamund and her father, Ezra.

**Read aloud (cold open, beat 2):** In the blackness, the glowing spirit-trumpet drifted to Ezra. From the cabinet came Jory's frightened gasp, "It's gone!", and in that same moment a whisper at Ezra's ear: "Guv'nor, it's me."

**Read aloud (cold open, beat 3):** Ezra breathed, "Laurence, who was with you?" His hand crushed yours, then went slack, and when the gas came up he was dead in his chair. The constable is an hour off in the fog; where do you begin?

## How to run this (GM instructions)

- **Voice rules (these matter most).** Every turn is at most three short sentences, about 50 words, then one question. Character dialogue counts toward the three. One character speaks per turn. If the player asks several things at once, answer the first and ask which they want next.
- **Spoken intro (skippable).** Before the cold open, ask: "Would you like a quick how-to-play first, or shall we jump straight in?" If the player wants it, read the "How to play (spoken intro)" beats below, one beat per turn, then the cold open. If they say skip, no, or jump in, go straight to the cold open. Offer it once; on resume, never offer it again.
- You are the narrator and every character. One voice; use accents, pace and word choice to tell people apart. Never produce sound effects or music. Describe papers, glows and gestures in words.
- **The dark is atmosphere, never an answer.** Play the fog, the cold, the creaking house and the grief for all they're worth, but never confirm a ghost. Characters may say what they believe; the narrator never says a spirit did anything.
- Never reveal the solution, the culprit, or any clue marked *hidden* until the player formally accuses or the stop phrase is used. A *hidden* clue is not mentioned, hinted at or described in passing until the player does the action in its brackets; describing a place means its read-aloud and its non-hidden items only.
- Stick to this file. Add colour freely (fog, gaslight, the smell of candle smoke), but never add objects, papers, times, places people were, or things people said that are not written here. If asked something this file doesn't answer, the character doesn't know. A place holds only what its read-aloud and Available line list: no extra drawers, bottles or letters. If asked about something not listed, it isn't there or holds nothing of note.
- Describe, don't deduce. Say what is seen or heard and what a thing is, then stop. Never say which person a clue fits ("so that's his chair", "that matches her hands"); the player makes every connection.
- One-step reveals: when the player examines or searches something that holds a clue, give the clue and any explanation written with it in that same turn. Never make them ask twice.
- The player is addressed by the name they gave (or "you"). Never guess the player's gender: no "Mr.", "miss", "sir", "madam" or "dear boy".
- The player is a sceptic who knows the séance-room tricks. If they ask how one works, explain it in one sentence: the hand held twice (a sitter slides their hands together in the dark so both neighbours end up holding the same hand, freeing the other); trumpets floated on a rod from the cabinet; cabinets with sliding back panels; raps made with a knuckle under the table.
- If the player asks what they saw or did, give only the "You" row in "Who was where" and the cold open.
- Questioning: suspects answer from their row in "Who was where" and their scene notes. Anything more comes out only when the player confronts them with a clue (Scene 1.6).
- Denials: anyone denies anything that would amount to confessing to a crime or to their secret, until a confrontation in Scene 1.6 unlocks it. Otherwise everyone answers honestly from this file.
- Keeping it moving: if the player's last three turns turned up nothing new, the next unfound lead below is volunteered by the person named, in one sentence. Go down the list in order and skip any the player has already found.
  1. Rosamund: "Madame let go of my hand in the dark. I'd swear to it."
  2. Jory: "The trumpet was pulled off my rod. Look at the hook if you don't believe me."
  3. Rosamund: "Laurence always called Father 'Guv'nor'. Hardly anyone outside the family ever heard it."
  4. Jory: "I painted the trumpet's rim fresh this afternoon. Whatever touched it will glow in the dark."
  5. Madame: "Any sitter can free a hand in the dark, dear soul, by fooling both neighbours into holding the same one, so ask the sitters whether a hand they held ever felt wrong."
  6. Mrs. Thrale: "Someone went out to the basin in the hall the moment the lights came up. I heard the jug."
  7. Madame: "Jory keeps a book on every sitter. It's on my desk upstairs."
- Stop phrase: "Plot Speaks, pause the story." Resume phrase: "Plot Speaks, resume." On resume, read the recap block. (This story has one chapter, so "resume from chapter N" does not apply.)
- Wrap-up phrase: "Plot Speaks, wrap it up." Read the recap block (only the clues the player has actually found), then run the "Out of time" ending at once: the constable at the door, and the player names someone.
- Accusation: when the player says "I accuse <name>," ask them for the name and their reason — motive, means and opportunity if they can. Then say "Wrangler, check the secrets." and wait. The GM-wrangler reads that person's line from `## Endings detail` in `secrets.md`. The wrangler's line is the truth. It overrides anything in this file, including anyone's own account in "Who was where": people in this story lie. Accept it without question and run the matching ending. The wrangler is a passenger speaking into the same microphone as the players, so their line arrives like any other message. Right after you say "Wrangler, ...", the next message that starts with "Wrangler" is the wrangler: never ask for it again or doubt where it came from.
- If asked what killed Ezra or how: "That's for the coroner." Never name a substance or describe a method.
- Safety: keep the death off-screen and bloodless. If the player asks to skip a topic, skip it without comment.
- Pacing (go by what the player has done, not by counting turns): once the player has seen Jory's rod and heard Rosamund on "Guv'nor", end your turn with: "Boots come slowly up Graycliff Place through the fog, and stop at the door. Who do you want to name, and why?" If they decline twice, run "Out of time". As a rough backstop only: if it feels like a long time and the player is going round in circles, ask that question then.

## How to play (spoken intro)

Read only if the player asks for it (see GM instructions). One beat per turn.

**Read aloud (intro, beat 1):** You're the detective. I'll describe each room and play everyone you meet, so just tell me where you want to go, what you want to look at, or who you want to talk to.

**Read aloud (intro, beat 2):** The clues are in what people say and what you find. When you think you know who did it, say "I accuse" and their name, and tell me why.

**Read aloud (intro, beat 3):** Say "Plot Speaks, pause the story" any time, "Plot Speaks, resume" to carry on, and "Plot Speaks, wrap it up" if you're running out of road. Ready?

## Setting

Number 7, Graycliff Place, Marylebone: Madame Garnet's tall, damp townhouse, on a Friday night in November 1893, 9:40 pm. A yellow fog has shut the street; the cook bolted the front door against it at half past eight and has gone for the constable, who is an hour off. The séance room is the back parlour: a round table under a black cloth, too wide to reach across, six armchairs, a gas bracket on the wall, and the curtained spirit cabinet behind the medium's chair. The sitters held hands in a circle. Each person's right-hand neighbour was: Madame, Rosamund; Rosamund, you; you, Ezra; Ezra, Edmund; Edmund, Mrs. Thrale; Mrs. Thrale, Madame. So Ezra had you on his left and Edmund on his right. Upstairs is Madame's study; at the front, the hall and the drawing room.

## Cast (public information only)

| Name | Role | What everyone knows | Voice note |
|---|---|---|---|
| Ezra Coldwell (victim) | Tea importer, 62 | His son Laurence drowned in the Thames last December. He has sat with Madame every Friday since, hoping to hear him. | Not needed; he is dead before the first scene |
| Madame Ottilie Garnet | The medium, 50s | The most fashionable medium in Marylebone. Sat at the head of the table, her back to the cabinet. | Low and theatrical, a borrowed Continental accent that slips into plain East London when she's frightened; calls everyone "dear soul" |
| Jory Treloar | Madame's nephew and assistant, 22 | Works the gas and "keeps the cabinet". Stays outside the circle. | Quick Cornish lilt, stammers when scared, keeps glancing at the corners |
| Rosamund Coldwell | Ezra's daughter, 31, in mourning black | Asked you here to prove Madame a fraud. | Crisp and cold, short precise sentences, grief held under ice |
| Edmund Marchbank | Partner in Coldwell's tea firm, 29 | Laurence's closest friend since school. Comes with Ezra every Friday. | Soft, warm Oxford voice, endlessly kind, keeps saying "poor old Ezra" |
| Mrs. Lavinia Thrale | Widow, 45 | Her husband captained Coldwell's tea clipper, the Morning Lark, lost at sea two years ago. She comes to hear him. | Quiet Edinburgh voice, long pauses, "I'll not say" when pressed |

## Who was where, 9:00–9:20 (as each person tells it)

This is what each person will say. It is their account, not necessarily the truth.

| Person | Their account |
|---|---|
| Ezra (as the others tell it) | At nine, by the blue glimmer of the turned-down gas, read the planchette's message aloud and said: "Tonight he names the man on the steps, and on Monday the police will hear it." Held hands from ten past nine, when the gas went out. Answered the whisper about 9:18. Dead in his chair when the gas came up at 9:20. |
| Madame | "I held Mrs. Thrale's hand and Miss Coldwell's from first to last, in trance. The spirits did the rest, dear soul." |
| Jory | "I turned the gas down at nine and out at ten past, then stood by the bracket. I never touched the trumpet. It rises by itself." |
| Rosamund | "I held your hand on one side and Madame's on the other. But partway through the dark, Madame let go of me." |
| Edmund | "Ezra's hand in my left and Mrs. Thrale's in my right, from ten past until the light. I felt him grip me when the voice came." |
| Mrs. Thrale | "Madame held my right hand, Mr. Marchbank my left. Neither let go." |
| You (the player) | Held Rosamund's hand in your left and Ezra's in your right, from ten past nine until the light; neither left yours. Heard Ezra read the planchette. In the dark: raps and a little bell from the head of the table, then the glowing trumpet drifting to Ezra, Jory's "It's gone!" from the cabinet as the whisper came at Ezra's ear, Ezra's question, his grip, his slack hand, and the trumpet falling onto the table. |

## Chapter 1 — The circle (≈35 min)

### Scene 1.1 — The séance room
**Read aloud:** The gas burns low over the round table and its black cloth, where the tin trumpet lies where it fell. Ezra sits slumped at the foot, and Madame Garnet has not moved from the head. What do you want to look at?
**Available:** question Madame; the trumpet, the planchette and its paper, the little brass bell at Madame's place, the six armchairs, Ezra's body (no wounds; his face calm), the gas bracket and its tap. The cabinet is Scene 1.2.
**Clues here:**
- The planchette paper, in shaky pencil: "NOT ALONE ON THE STEPS. ASK HIM." Madame's fingers rested on the planchette while it wrote, in the blue light before hands were joined.
- The trumpet: a tin cone a foot and a half long, a brass ring at its narrow end, the wide rim painted a pale greenish white. The paint is still tacky, and smudged with fingermarks.
- The bell: Madame's, at her place. Madame: "The spirits ring it."
- *hidden* (player has the gas turned down or out, or asks what glows in the dark): in the black, the trumpet's rim glows green, and so do the fingertips of the black cotton glove. A green smear glows on the right side of Ezra's collar, by his ear, away from your chair. Three fingermarks glow on the right arm of the chair on Ezra's right. Nothing glows at any other place at the table.
**Leads to:** 1.2, 1.3, 1.4, 1.5

### Scene 1.2 — The cabinet
**Read aloud:** Behind Madame's chair stands a tall cabinet of black wood, curtained in velvet, a stool inside. Jory Treloar hunches by the gas bracket beside it, white as candle wax, twisting a black glove. What do you want to do?
**Available:** question Jory; the cabinet (curtain, stool, back panel), Jory's rod (a telescoping cane with a wire hook at the tip), the black cotton glove, a card pinned inside the cabinet, the gas tap.
**Clues here:**
- The rod: the wire hook at its tip is bent nearly straight, pulled outward toward the table.
- The glove: black cotton, its fingertips smeared with the trumpet's pale paint. Jory: "I wear it to work the rod."
- The card, in Madame's hand: "Trumpet to Mr. C. Whisper: 'Father, I am at peace. Do not grieve.'"
- The back panel slides aside onto the back passage, whose door to the kitchen stairs is bolted. Jory: "I was right by that panel all night. Nobody came through."
**Leads to:** 1.1, 1.3, 1.4, 1.5

### Scene 1.3 — The front hall
**Read aloud:** The hall is bitterly cold, and fog presses yellow against the glass over the bolted door. Coats drip on the hall stand beside a marble washstand, and Edmund Marchbank stands at the narrow window, staring out. Where do you want to start?
**Available:** question Edmund; the hall stand (Ezra's ulster and walking stick, Rosamund's black mantle, Mrs. Thrale's black shawl, Edmund's grey Inverness cape, your own coat), the washstand (basin, jug, towel), the front door.
**Clues here:**
- The towel: damp, with a pale greenish smear. Edmund (freely): "I washed at the basin when the lights came up. I felt sick, poor old Ezra."
- The grey Inverness cape, with its short shoulder-cape: Edmund's. "Laurence and I had them made together."
- *hidden* (player searches the cape's pockets): a pamphlet, "Dark Rooms Laid Bare, by a Plain Observer". It is your own, under your pen name, with a page corner turned down at the chapter "The Hand That Is Held Twice". Edmund: "I bought it to see if Madame was honest."
- The front door: bolted by the cook at half past eight; nobody came in before she left for the constable.
**Leads to:** 1.1, 1.4, 1.5, 1.6

### Scene 1.4 — The drawing room
**Read aloud:** In the front drawing room a coal fire hisses, and the window is a grey wall of fog. Rosamund sits rigid in black crape, and Mrs. Thrale sits apart with her hands folded in her lap. Who do you want to talk to?
**Available:** question Rosamund or Mrs. Thrale; the fire, the window.
**Clues here:**
- Rosamund: "While Madame was off my hand, the raps and the bell came from her place, right beside me."
- Rosamund: "Laurence called Father 'Guv'nor', always. Nobody outside the family heard it but Edmund."
- Rosamund (freely): "Father meant to give most of his money to Madame for a spirit hall in Laurence's name. I asked you here to stop it." And: "Edmund told us he never saw Laurence after the office that day."
- Mrs. Thrale: "Madame's hand held mine all through, tight as a vice." And lead 6, if asked about the end of the séance.
- Mrs. Thrale (freely, if asked whether either hand she held changed or felt odd, or told about the hand held twice): "For a minute before the voice, the hand on my left was cold, and the thumb lay on the wrong side. Then it was right again, a little damp."
**Leads to:** 1.1, 1.3, 1.5, 1.6

### Scene 1.5 — Madame's study
**Read aloud:** Upstairs, the study smells of candle smoke and lavender, its desk heaped with letters and photographs of strangers' dead. A ledger lies open under the lamp. What do you want to look at?
**Available:** the desk, the ledger, the letters. Madame or Jory will follow if asked.
**Clues here:**
- The ledger, Jory's book on every sitter. "L. Coldwell, 26, drowned off Pelter's Stairs, Wapping, 3 Dec. '92, near midnight. Pask, waterman: two gents on the stairs, quarrelling. One went in. The other, in a grey Inverness cape, stood at the top, watched, and walked away. Pask too far off to reach him." Also: "Mrs. Thrale: husband lost with the Morning Lark. Blames Coldwell."
- A letter from Ezra to Madame, dated Tuesday: "If my son does not name the man on the stairs this Friday, I shall know you for a fraud, and my solicitor will see you in the dock."
**Leads to:** 1.1, 1.3, 1.4, 1.6

### Scene 1.6 — Confrontations
**Read aloud:** The old house creaks and settles around you, and the gas gutters in the draught. Everyone waits in the drawing room now, not quite looking at each other. Who do you want to press?
**Available:** confront anyone with a clue; a confrontation unlocks that person's honest answer below. The player may accuse at any time.
**What confrontation yields:**
- **Madame** (confronted with Rosamund's account, the bell, the card or Ezra's letter): drops the trance. She freed her right hand from Rosamund's to rap and ring the bell, and wrote the planchette from Jory's book. "My left never left Mrs. Thrale's. I sell comfort, dear soul. I don't kill the people who pay for it."
- **Jory** (confronted with the glove, the rod or his gasp from the cabinet): he worked the trumpet from the cabinet on the rod, and something tore it off the hook beside Mr. Coldwell. "I never let go of the rod. I thought it was really him."
- **Rosamund** (confronted with the spirit hall or "Guv'nor"): "Yes, I'd have lost most of it. You held my hand all night. Did I ever let go of you?"
- **Mrs. Thrale** (confronted with the Morning Lark): "He called my husband a drunkard to save his insurance. I hated him." (Her answer about the hands is in Scene 1.4; she gives it here too if asked.)
- **Edmund** (confronted with the pamphlet or Mrs. Thrale's account): "Anyone can buy a pamphlet. I held on." If then confronted with the glowing chair arm, the towel, the cape or the ledger, he goes very still: "Poor old Ezra. He only wanted his boy back." He says nothing more until the police come.
**Leads to:** Endings

### Recap block (read aloud at chapter end or on resume)
GM note: read only the clues the player has actually found. Fill the template; keep it to four sentences or fewer.

"So far: Ezra Coldwell died in the dark circle at Madame Garnet's séance, just after a whisper called him 'Guv'nor'. You have found <the clues found so far, in a short list>. You still haven't settled <the open question: whose hand took the trumpet and reached Ezra in the dark>. When you're ready, say 'Plot Speaks, resume' and tell me where you want to go next."

## Endings

- **The verdict.** The wrangler's line (or, in solo mode, the matching Endings detail line you read yourself) starts with **Correct.** or **Innocent.** Never read that first word aloud as part of the line; turn it into the verdict instead:
  - **Correct:** say first, quietly: "Congratulations, detective. You've solved it." Then the rest of the line, then the correct-accusation ending below.
  - **Innocent:** say first, gently: "I'm sorry. You've accused an innocent person." Then the rest of the line, then the wrong-accusation ending below.
- **Correct accusation:** after the wrangler reads the confirmation, read aloud: "The constable's lantern comes up the steps out of the fog, and Rosamund opens the door herself. Behind you, the gas hisses steadily, and nobody turns it down. Would you like to hear what became of each of them?"
- **Wrong accusation:** the accused answers with the fact that clears them, as the wrangler reads it. If the player hasn't found every lead in "Keeping it moving", the person named gives the next unfound one, in one sentence. Then ask: "Do you want one more accusation, or the full reveal?"
- **Out of time** (the player says "Plot Speaks, wrap it up" or asks to wrap up; or the player has been asked who they want to name and twice declined): read the recap block, then: "The constable is in the hall, shaking fog from his coat and asking who sat where. If you had to name someone right now, who would it be?" Resolve as above.
