On the screen swam a fish. Not the cartoon ease of aquarium animation, but a living, breath-still fish whose scales were the color of dusk. It did the impossible: it lived upside down. Against the pull of gravity and the expectation of movement, it drifted with serene, stubborn refusal. The camera lingered on it the way a camera lingers on a face about to confess a secret—intimate, patient, almost apologetic. The soundtrack was thin at first: a clock, a low hum, the wet echo of tides. Then a voice, maybe from the projector itself, read a letter that never named the writer.
