The Listening Glass sat on a mail cart in the annex behind Ponyville City Council, warmer on the left than the right. Ember Flint had her sleeves rolled and a city rag folded under the near caster. Four screws lay in a jar lid that still smelled like pickled beets. The Evening Margin was spread under the jar so the ink would not mark the floor. The exposé took the bottom of the front page and called itself blistering before anypony else could.
The glass is a breadbox of brushed brass with a blue wafer over the seam and no switch Ember has found. The council bought it in late summer from North Latch, a Las Pegasus concern that demonstrates its work in rooms with the lamps already low. The purchase order, which Ember files with the other things that hum, lists one thousand eight hundred bits and the purpose "early listening." At the Ponyville Market demonstration a North Latch pony asked a crowd to think of a grievance quietly. The box ticked. Ponies applauded the tick. Ember was there for the extension cord.
The Margin's piece ran before dawn. It named the glass a sealed authority and a mystery the realm had been too polite to fear. It said the council had outsourced attention. It said the wafer was an insult. It did not say what the brass was hiding. A diagram occupied a quarter of page four: a square, the caption "interior withheld," and a credit to the illustrator. The exposé ended on one sentence. Ponyville would be safe when it learned to befriend what it could not open.
Council clerks stapled that sentence to a half-sheet and set it on the front desk beside the visitor book. The half-sheet is titled Friendship Report, the way all the half-sheets are, and leaves a line for a name. By midmorning twelve ponies had signed. One had copied the square from page four and written, under it, the part we are not to know.
Luna Starlight's foreword sat above the fold in the type the Margin saves for morals.
"Mystery is a teacher," she wrote. "Our task is to remain seated."
She was on a train to Las Pegasus before the cart squeaked. Silver Hoof, who signed the order, read the foreword in the corridor and did not go in.
"The demonstration ticked," he said. "That was the line we put in the order."
He did not look at the jar lid. The exposé had used the firm's name nine times and the word interior once.
Ember had the hatch up because the left caster clicks when the wall boiler starts, and the boiler starts on the hour. She put the rag under the caster on Monday. The click stopped. On Tuesday a small kettle noise came back in the brass, and she took the four screws out with a driver from the lost-and-found. Inside she found a mica card, a coil of ordinary wire, and a rune tile with a Ponyville Market sticker on the back. The sticker said six bits. The tile's printed name was Hearth Hug. A folded card in a child's type said the glass would lose its nerve if nopony read the enclosed lesson aloud at the start of each watch.
She read it once, the first night, because the card said to. The lesson was forty words and ended on the word together. The kettle noise arrived halfway through, which was also when the boiler came on. She has not read the card since. The noise has kept the boiler's hours. She left the screws in the lid while the Margin was still wet, so she would not scar the brass.
The form she filed is three lines: caster, boiler, six-bit tile with sticker. A supervising pony returned it before supper with the lesson line empty and a red stamp asking her to complete the reflection. The sample reflection, printed in advance, says the filer has sat with mystery and grown.
Ember slid the form under the rag so both would stay with the cart.
"I wrote boiler," she said. "They sent it back asking what I learned."
At dusk the half-sheet had one signature line left. Somepony had written we will try beneath the exposé's last sentence. The glass was warm on the left. The rag was dark where the caster sweated. Nopony had read the forty words since Tuesday, and the light in the seam had not gone out.
