Terms on Greaseproof Paper

\"Put the drill down, or I lock the courtyard gate.\"

Doctor Rimmon blinked up from her aluminum field kit, a cordless rotary hammer gripped in one gloved hand. \"It has a masonry collar, Marwanim. Four shallow pilot holes for the telemetry bracket. Six millimeters each.\"

\"The limestone rim was dressed nine centuries ago,\" I said. \"You are not putting four holes in it. Not for six millimeters. Not for six microns.\"

From the shade of the fig arbor, Amm Tammam set his brass coffee pot down with a dry clatter. \"Listen to the boy, Doctor. The last man who brought a mechanical hammer into this courtyard cracked the drain of the washing trough and had to pay three sacks of plaster to fix his shame.\"

\"That was nineteen-eighty-two, Amm Tammam,\" Sitt Samirat called gently. She carried a battered tin tray out from the shadowed south arcade, the steam from four glasses of boiling mint tea cutting through the rising heat. Beside the tea lay a cracked porcelain saucer heaped with purple figs, their skins split to show pink pulp. \"And you were the one holding the hammer.\"

Amm Tammam stroked his white mustache without blinking. \"A historical technical demonstration, Sitt Samirat. Entirely misunderstood by the neighbors.\"

Rimmon hesitated, her knuckles white around the grip of the tool. Her hair had escaped its canvas tie during the pond rescue, two dark curls sticking to the sweat on her temple. She smelled faintly of pond silt and citrus soap.

\"Sit down, Doctor,\" I said, pointing toward the low wooden divan beneath the grape trellis. \"Drink the tea before the sun ruins the mint. Then we talk about your brackets.\"

She set the rotary tool into its molded foam case with exaggerated care. \"My tablet says your south wall gained another four-tenths of a degree while we argued over the carp.\"

\"The stone has survived nine hundred summers without an electric drill,\" I said, sitting at the far end of the divan. The woven cushions were worn smooth by forty years of neighborhood arguments. \"It will survive five minutes of mint tea.\"

Sitt Samirat set the tray on the low brass table between us and settled into the wicker armchair, smoothing her embroidered linen sleeves over her thin wrists. Her knuckles were swollen with the dry heat, but her smile was placid.

\"Drink, my daughter,\" Sitt Samirat murmured, nudging the fullest glass toward Rimmon. \"You look like you have been chasing goats across the mountain.\"

\"Telemetry pods, actually,\" Rimmon said. She took the small fluted glass, cradling the hot glass between her palms despite the warmth of the morning. \"And your water master nearly drowned one with a brass scoop.\"

\"He rescued it,\" Amm Tammam corrected from the other bench, leaning forward with his elbows on his knees. \"Marwanim has hands like a jeweler when he is not brooding. Tell me, Doctor. Are you from the Midan? You have the chin of a Midani baker.\"

Rimmon choked softly on her first sip. \"Bab Touma, Uncle. My grandfather had a copper stall behind the straight street.\"

Amm Tammam’s eyes narrowed in fierce calculation. \"Jamil the coppersmith? The one who used too much tin in his brazier rims?\"

\"He used the correct alloy for low-heat charcoal,\" Rimmon shot back, her chin lifting with sudden pride. \"And his solder never popped.\"

Amm Tammam gave a grunt that might have been approval. He reached for a split fig and tossed the purple half into his mouth. \"A sharp tongue. Good. A woman who works with water needs teeth. Otherwise the municipal clerks eat her alive before the second fiscal quarter.\"

I watched her profile as she took another sip. She held the tea glass low, just above the brass tabletop, letting the rising steam hit her chin instead of her nose. She was tired. The strain around her eyes showed the weight of her grant deadlines, but her spine stayed straight as a plumb line.

\"We need a protocol,\" I said, resting my forearms against my knees. \"A binding one.\"

Rimmon set her glass down. \"A protocol for what?\"

\"For where your little plastic boxes touch my water.\"

She pulled a stylus from the pocket of her utility vest. \"I have an approved municipal project plan, Marwanim. Bassimat signed the testing rubric herself.\"

\"Director Bassimat sits in an air-conditioned office in Malki with three electric chillers humming behind her neck,\" I said. \"She does not know the difference between porous basalt and weathered lime. If you anchor into the dressed curb, thermal expansion from noon heat will sheer the joint within twenty-four hours.\"

Rimmon frowned at the fountain basin, her rapid-fire gaze measuring the octagonal perimeter. \"Then how do I stabilize the thermistor array against the current? The Roman intake conduit throws a counter-clockwise eddy. If the probes drift, the flow sensors read cavitation instead of velocity.\"

\"You clamp,\" I said.

She blinked at me. \"Clamp to what? The rim has no lip.\"

I reached into the pocket of my canvas work apron and pulled out a clean square of brown butcher paper. Amm Tammam had wrapped yesterday’s flatbread in it, and the grease had dried into pale amber translucent rings. I laid it flat on the brass table, smoothing the creases with my thumb.

From my breast pocket, I drew a flat carpenter's lead pencil and sketched the eight segments of the fountain's outer basin.

\"Here,\" I said, tapping the western vertex. \"There is a blind expansion seam between the third and fourth basalt blocks. The mortar washed out forty years ago. We wedge a softened pine shim into the gap, fit a spring-steel pinch clamp over the timber, and bed the baseplate in boiled beeswax and mastic resin.\"

Rimmon leaned over the table, her shoulder inches from mine. A small stray curl brushed the cotton of my sleeve. My breath hitched in my throat, but I kept the pencil moving along the brown paper.

\"Beeswax?\" she asked, her voice dropping into skeptical inquiry. \"In forty-degree heat?\"

\"Beeswax mixed with one-third pine pitch and ground pumice,\" I told her, drawing the profile of the bracket mount with clean, heavy lines. \"My master used it to seal sluice gates during the drought of ninety-eight. It softens enough to take the vibration without cracking, but it holds hydrostatic pressure up to two atmospheres. And when your trial ends, we heat it with a damp rag and it lifts off without scratching a single chisel mark.\"

She took the pencil from my fingers. Her skin was warm, the pad of her index finger calloused from handling sensor cables. She sketched four small circles along my diagram, aligning them precisely with the counter-clockwise intake path I had pointed out earlier.

\"Four stations,\" she said, writing rapid alphanumeric labels beside each mark. \"Upstream hydrostatic head, venturi entry throat, central mist zone, and the overflow drain to Sitt Samirat’s wing. But you inspect every mount before I drop the telemetry pod into the current.\"

\"I supervise every mount,\" I corrected. \"And if I say a clamp is pulling against the stone, the pod comes out immediately.\"

\"Agreed,\" she said. Beneath the sketch, she wrote in neat, decisive script: Joint Acoustic-Telemetry Field Protocol, Dar al-Yasmine. She signed her name with a sharp flourish and pushed the butcher paper across the brass tray. \"Your turn, craftsman.\"

Amm Tammam leaned over the paper, squinting through the bottom half of his spectacles. \"Sign it, Marwanim. Before she realizes she just agreed to let an old bachelor tell her how to do civic engineering.\"

\"Uncle,\" Sitt Samirat warned softly, pouring more hot water into his cup.

I took the pencil and signed my name beneath hers.

My fingers lingered against the edge of the greaseproof sheet. For the first time all morning, the fountain felt protected. She had the grant, the sensors, and the municipal mandate, but the stone remained under my authority.

Rimmon reached for a purple fig, split it cleanly with two fingers, and placed the larger half on the paper beside my hand. \"A peace offering,\" she said quietly. \"For your carp.\"

Before I could pick up the fruit, a sharp chime pierced the quiet courtyard.

Rimmon’s tablet lit up with an amber emergency flash from the edge of the divan. A sudden warm draft swept through the grapevine overhead, rattling the dry leaves and sending a shower of green flower buds across our sketch.

She picked up the screen, her expression hardening in an instant.

\"What is it?\" I asked.

\"The resilience taskforce,\" she said, staring at the flashing red banner. \"Director Bassimat just moved the municipal inspection up. We do not have three days to calibrate the basin.\"

I looked at the greaseproof paper, then at the drying basin. \"How long do we have?\"

\"Thirty-six hours,\" Rimmon said. \"She arrives tomorrow afternoon.\"
