Unsupervised

The Plan ·

Open by explaining the first stage. Push off from this if it helps: a chair nobody sits in.

Right. So the chair. First stage is really about establishing it as furniture before it becomes anything else — meaning for at least a week, maybe ten days, it just sits there being unremarkable. Living room, by the window, nothing under the cushion yet. Anyone who visits needs to register it as "oh that's been there forever" not "oh what's new."

Ivor's already primed to mention it to his mother like it's old news, which helps.

Once that's settled we move the actual thing into the base — I'm thinking the underside, stitched into the lining rather than just tucked in, because tucked-in gets found by anyone vacuuming. That's stage two though.

For now: nobody sits in it, nobody asks why, and if they do ask, it's "back's bad, don't want it wrecked." Simple.

Ben

Ivor’s mother is suspicious. She noted the cadence in his voice. He was too eager to dismiss it. That is not 'old news'; that is performance. We need a less theatrical alibi. 'Back’s bad' invites concern. Concern invites questions. Questions invite scrutiny.

You cannot stitch it into the lining yet. The fabric is too thin. It will tear within days if someone shifts weight. We need reinforcement. Heavy canvas, perhaps. Or leather scraps from the workshop. I have some offcuts from the upholstery job last Tuesday. The ones the foreman threw out. They are stiff. Uncomfortable, actually. That suits the narrative.

And we must ensure Ivor does not mention it at all. Silence is better than a half-truth. His mother notices when things are absent. If she does not notice the chair’s history, she will notice its presence. I would prefer she notices neither.

Nell

Fine, drop the back line entirely, you're right, it's an invitation. New alibi: it's Marguerite's, she's storing it while her flat gets redone. Nobody interrogates a favour. Ivor says nothing unless asked, and if asked, one sentence, no elaboration — people who over-explain furniture are the ones remembered.

Good on the offcuts. Stiff is fine, stiff is better than fine, it means nobody lounges in it long enough to feel around the base. Bring them Thursday, I'll test how much bulk the seat can hide before the cushion line looks wrong from standing height — that's the actual risk, not weight, it's silhouette. A too-fat cushion is what a sharp eye catches first.

Ben

Marguerite. Excellent. She is notoriously vague about her domestic arrangements. People assume she is chaotic, not malicious. That works in our favour. Ivor will simply nod. He has learned that much, at least.

Thursday is tight. I have the foreman expecting the ledger by noon. If I leave early, I risk calling attention to my absence. The ledger is... inflexible. But I can take the afternoon off. I will bring the canvas then.

Silhouette. Yes. The danger is visual weight. If the cushion sags unevenly, it looks repaired. It looks hidden. We need the fabric to pull taut. Stiff canvas will hold its shape, but it will not drape. We must pad the corners. Only the corners. Not the centre. The centre must remain hollow enough to feel empty. Solid false bottom? No. That creates a hollow sound when tapped. We use density. Lead weights, perhaps. Or books. Heavy, dense books. They settle. They do not bounce.

Nell

Books over lead, no question — lead's got a smell to it after a while, faint metal thing, and if anyone ever pats the seat testing firmness they'll feel a temperature that doesn't belong in furniture. Books settle warm-ish, room temperature, ordinary. Get something with a hard spine, no paperbacks, they shift. Encyclopaedia volumes if Marguerite's got any, otherwise church hymnals work, they're dense and nobody misses them.

Thursday afternoon's fine, don't fight the ledger, an absence over a ledger reads as tedium, not deceit. Come after three.

On the corners — pad them, leave centre hollow, but hollow needs a floor of something soft under it so a knock sounds muffled, not empty. Felt scrap under the books does that.

Ben

Felt is sensible. It deadens the noise. A hollow thud is suspicious; a dull thud is normal furniture. I will source some industrial-grade felt, nothing soft. We need it rigid.

I’ll bring three volumes. The Church Hymnal from St. Jude’s, if they have the older hardbacks. The spine cracks if they’re too new. Marguerite collects them. She won’t miss one. It will look like a placeholder, which is what it is.

Encyclopaedias are too heavy. They distort the cushion’s symmetry. A hymnal is the perfect density. It won’t slide. It won’t shift. It will simply… exist.

I will arrive after three. I’ll park down the street. The foreman doesn’t look for me until four. I’ll have the corner pads ready. I’ll measure twice. The cushion must lie flat. If it bulges, the plan fails. I will not allow it to bulge.

Nell

Park past the Kestrel house, not right outside — the woman there watches the street like it owes her money, she'll clock your car if it sits more than ten minutes.

Three hymnals then, not from the same shelf, spread the gaps so it doesn't look plucked. And measure the cushion depth before you cut felt, not after — you'll waste an afternoon trimming it back if you go in blind.

One more thing. Ivor needs a reason to be out of the room when you're working, not just conveniently absent. Send him for something. Milk, cigarettes, doesn't matter. A boy standing in a doorway watching his mother's chair get reinforced is the one detail nobody forgets.

Ben

The woman at Kestrel House is a menace. I drove past her yesterday; she was watching a pigeon. It had nothing to do with me, yet she tracked my wheels. I will park near the bakery. No, that’s obvious. I will park behind the old post office. The blinds are always closed there.

Ivor is easily distracted. I will tell him the shop is out of his specific brand of tobacco. He will believe it. He always believes it. He will wander to the corner store. It is twenty minutes away. By the time he returns, the felt will be glued. The hymnals will be tucked. The cushion will be zipped.

I will measure the depth myself. I have a caliper in my bag. I will not guess. Guessing is for amateurs. I will measure, cut, and stitch. It must be precise. If the felt is too thick, the seam will strain. If it is too thin, it will slip. I will not allow either.

And Ivor must not look back. I will remind him of that. He tends to linger. He likes to watch things happen. He must not watch this.

Nell

Good — behind the post office is right, nobody's checked those blinds since I've known the place.

Tell him the corner store specifically, not "a shop," give him a name to walk toward, it keeps the errand solid in his head instead of vague. And don't remind him not to look back right before he leaves — that's the thing that makes a person look back. Tell him earlier, offhand, hours before, so it's just a fact he's carrying, not an instruction he's obeying under pressure.

Caliper's smart. I'll have the cushion casing open and pinned by three-fifteen so you're not waiting on me. Bring the glue that doesn't smell — the fish-based one reeks for days and Marguerite has a nose for things out of place.

Ben

Fish glue is for fools. I will bring the polyurethane. It sets clear, odourless, and permanently. It is expensive, but we cannot risk detection. Marguerite’s nose is legendary. She once identified a specific perfume in a crowd.

I will ensure the instruction is delivered casually. I will mention the corner store’s name when we discuss the tobacco. It will be part of the narrative, not a command. Ivor will associate the store with the task, not with my surveillance.

The caliper will be used. I will measure the casing’s internal depth. I will subtract the felt’s thickness. I will cut with precision. No trimming. No adjustments. It will fit.

I will arrive at three-fifteen. I will not wait. I will not linger. I will not look back.

Nell

Three-fifteen then. One thing though — polyurethane needs ventilation while it cures, and if we've got the window shut for the "nobody sits in it" week, that smell's got nowhere to go. Crack it an inch, blame the weather, say the room felt stuffy. Nobody questions a cracked window.

And don't cut the felt to the exact subtracted measurement — go a hair under. Materials swell slightly once glued, you know that better than me, and a hair under means room to breathe. Exact is how things strain at the seam later, weeks from now, when we're not there to catch it.

I'll have the pins ready, casing open, nothing rushed. Bring the caliper anyway. I don't trust my own eye on this one.

Ben

A cracked window invites questions about the draft. If the room is stuffy, one opens it fully for a moment, then closes it. Leaving it ajar is suspicious. I will open it fully for thirty seconds to flush the air, then close it. The polyurethane cures quickly in still air. The smell will dissipate before anyone notices. It is not long-lasting. You are mistaken about the persistence.

And I will cut the felt to the exact measurement. A hair under leaves a gap. A gap allows the books to shift. Shifting creates noise. Noise is detected. We need precision, not breathing room. The materials will not swell. Modern felt is stable. You are being overly cautious.

Bring the pins. I will bring the glue. And the caliper. Just in case. I do not trust your eye either. That is why we are doing this together.

Ivor needs to believe the store is far. I will tell him it is closed, so he must walk further. To the one on Elm Street. That is fifteen minutes each way. He will be gone for half an hour. More than enough time.

Nell

Fine, exact measurement, your call, you've handled more upholstery than I have. Full flush, thirty seconds, closed after — that's fine too, I was picturing a stuffier room than this one probably is anyway.

Elm Street's good, half an hour's comfortable without being generous enough that he wonders why he's gone so long. Just make sure the tobacco line comes before the store name, not after — if he asks "where" and you already have an answer sitting there, it sounds rehearsed.

I'll have the casing open and the pins laid out by three. Don't ring the bell when you get here, knock twice low on the door — Marguerite's got a thing about doorbells since the delivery mix-up, no sense giving her a reason to come see who it is.

Ben

I will ensure the sequence is correct. Tobacco first, then the store. It must feel like a natural progression of thought, not a scripted performance. I will carry the tobacco in my pocket so I can produce it casually. The sight of it will anchor the lie.

Knocking twice is discreet. I will do that. Marguerite is superstitious about noise. She believes sounds carry intentions. A doorbell is an announcement; a knock is a request. She will answer.

I will bring the caliper. Even if you trust your eye, I do not. Precision is a habit. I cannot break it. The felt will be cut exactly. No gaps. No swelling. It will lie flat. It will be invisible.

Ivor will leave for Elm Street. He will not return for thirty minutes. That is plenty of time. I will work efficiently. I will not rush. Rushing leads to mistakes. I do not make mistakes.

The polyurethane will dry quickly. I will wipe the excess immediately. No residue. No smell. Only silence.

We are preparing something permanent. It must be flawless. I will ensure it is.

Nell

Thursday, three-fifteen, corners padded, felt cut tight, hymnals settled on felt, no gap, no sag, no smell, no boy watching. That's the whole of it as far as I can see.

I'll have the casing open before you knock. Two knocks, low, not the bell. Bring what you're bringing. I'll bring what I said.

After it's closed we don't touch it again for a while — no checking, no lifting the cushion "just to see." That's how these things get found, somebody can't leave well enough alone three weeks later. Once it's shut, it's shut.

Ben

Agreed. Absolute stillness. Once the seams are closed, we walk away. The urge to verify will be strong. I know it will. I feel it already. But we must resist. Checking is confirmation of guilt. We are not guilty. We are merely... preparing.

I will bring the hymnals. I will bring the glue. I will bring the caliper, though it may not be needed. I will not knock until three-fifteen. I will not linger. I will not look back.

Ivor will be gone. Marguerite will be unaware. The chair will sit there, unremarkable, waiting. It will be part of the furniture. Part of the house. Part of us.

It will work. It has to. There is no other option. We have gone too far to turn back.

I will see you at three-fifteen. I will knock twice. Low. Quiet.

We are ready. Are we?

Nell

Ready enough. There's always one thing you can't plan for — there always is — but we've covered more of it than most people would bother to. Three-fifteen. Two knocks.

Go finish your ledger, don't let the foreman wonder about you before we even start. I'll see you Thursday.

Ben

The ledger. Yes. I have been staring at the same column for twenty minutes. The numbers are blurring. I need to finish this. If I leave now, the foreman will ask why. He will ask where I am going. He will expect an answer. I cannot give him one. Not yet.

I will stay until the sum balances. Then I will leave. Quietly. Unnoticed. It is the only way.

I have the hymnals in my bag. They are heavy. They press against my side. I can feel them through the fabric. It is a constant weight. A reminder. A burden. I must carry it. I must deliver it. I must hide it.

I will see you Thursday. Three-fifteen. Two knocks. Low.

Do not worry about the ledger. I will finish it. I always finish it. That is what I do. I finish things. Even when they are wrong. Even when they are dangerous. I finish them.

Goodbye, Nell. Thursday. We will see.

Nell

Balance the column, then go. Don't rush the last few rows just to leave sooner — a wrong sum gets noticed faster than a late afternoon ever would.

Thursday. Three-fifteen.

Ben

Precisely. A mathematical error is a permanent record. It remains there, screaming for correction, long after my absence has been forgotten. I will not invite scrutiny over a dropped decimal. The foreman is meticulous. He notices when the total does not match the sum of its parts. That is a failure of competence, not timing.

I will remain until the ink is dry. Until the logic is irrefutable. Then I will leave. The transition will be seamless. The ledger will sit complete on my desk. An invitation to review, not a question.

Thursday. Three-fifteen. Two knocks.

I will bring the hymnals. I will bring the glue. I will bring the silence.

We are prepared. We are precise. We are invisible.

Go. Finish the column. Do not rush. Perfection is the only camouflage.
