Film noir detective investigates who ate the last pizza slice

15-second FILM NOIR comedy short, storyboard as visual reference. 1940s black-and-white noir - stark high-contrast monochrome, hard venetian-blind shadows, drifting cigarette smoke, rain on windows, dramatic low-key chiaroscuro lighting. Slow, moody, deadpan. Photorealistic period look. 0-1.9s CRIME SCENE: open on an empty greasy pizza box on a table, one lonely crumb left, a hard spotlight on it, smoke drifting, blind-slat shadows. 1.9-3.8s DETECTIVE: low angle - a trench-coated detective in a fedora, half his face in shadow, cigarette glowing, narrowed eyes. 3.8-5.6s LINEUP: three nervous roommate suspects against a wall under a harsh interrogation light, sweating. 5.6-7.5s SUSPECT ONE: close-up as a roommate leans into the light, wide-eyed, mouthing a denial, sweat beading. 7.5-9.4s EVIDENCE: the detective slams a photo on the table - a smear of tomato sauce - gloved hand pointing, dramatic overhead light. 9.4-11.3s TURN: his eyes slowly shift and narrow toward something low off to the side, smoke curling past his face. 11.3-13.1s CULPRIT: a cat sits in a pool of shadow, a fleck of tomato sauce on its whisker, staring back with cold indifference, eyes catching the light. 13.1-15s GETAWAY: the cat turns and struts into the darkness, tail high, no remorse; the detective frozen in defeat behind it. Hold. Camera: slow noir push-ins, low dramatic angles, hard shadow reveals, a slow tilt to the cat. Moody and deliberate. No text, no captions.
