A House Built to Listen [SFX: Fireplace crackles. Blueprint unfolds] NARRATOR: Morning did not reach Mourning House so much as dilute its darkness. Ada spread the original building plans across the dining table. Gideon had rebuilt the manor around an older monastery and drawn every alteration himself. The plans showed speaking tubes between bedrooms, counterweight shafts beside the organ, and a service lift that officially ended beneath the kitchen. ADA MERCER: The bell we heard did not come from the tower. The pitch is wrong. Imogen, you recorded it? IMOGEN ROOK: Every minute since I arrived. Gideon hired me to catalogue the wax cylinders in his archive. Listen to the decay. [SFX: Wax cylinder playback. Low bell resonance] IMOGEN ROOK: A real tower bell rings into open air. This note has a short tail and a wooden reflection. It came through a speaking tube. PETER BELL: There is a practice bell under the organ. Master Gideon used it to test the house alarms when he was a boy. CELESTE MOURNING: You told the police it had been dismantled. PETER BELL: I believed it had. NARRATOR: Ada removed a panel beneath the organ. Behind it waited a bronze bell no larger than a soup bowl. A cord ran upward through a pulley and vanished into the wall. The cord was wet with fresh machine oil. LEON VALE: A delayed mechanism explains the sound, not a body behind a locked door. ADA MERCER: Correct. It explains why the killer needed us to agree on nine o'clock. NARRATOR: Gideon's tea contained foxglove, but the cup held no residue below the final sip. Poison had been placed on the rim, not brewed into the pot. Celeste had poured the tea at seven. Peter had carried it upstairs. Leon had brought Gideon papers to sign. Imogen had entered later to collect a cylinder. Every hand had approached the cup. IMOGEN ROOK: Gideon recorded a new will yesterday. He said paper could be altered but a voice had a shape. LEON VALE: There is no new will. I keep every executed instrument. [SFX: Cabinet drawer slides. Empty wooden slot] NARRATOR: In the cylinder cabinet, one numbered slot was empty. Its label read: NINE O'CLOCK, FOR ADA MERCER. The dust around it carried the clean curve of a recently lifted tube.
