The Steamship Logbook

# Nautical

A passenger is found deceased in their locked cabin aboard the steamship Oceanic. A single porthole is discovered ajar. The investigation examines discrepancies in the ship's mechanical logbooks and the personal timelines of the crew and passengers.

tech icon Initial Crime Scene

The scent of linseed oil and brass polish hangs heavy in the air as you step onto the bridge. From the engine room below, a low, constant thrum vibrates through the deck plates. Your eyes fix on the large, glass-domed chronometer drum, its ink needle tracing a continuous line on the paper ribbon. To your left, wax seals on correspondence pouches in the chartroom tray gleam dully. Ahead, the clockwork door-position indicators on the staterooms hold a rigid stillness.

tech icon Crime Scene Environment

The environment is dominated by a lighting profile of weak, diffuse daylight filtered through salt-crusted glass and supplemented by the steady, amber glow of brass oil lamps. The humidity is high, carrying a persistent, cool dampness that clings to wood and fabric. The acoustic density is layered: a deep, mechanical thrum from the engine room provides a constant baseline, punctuated by the rhythmic click of clockwork mechanisms and the occasional, distant toll of a ship's bell.

tech icon Investigation Constraints

The world operates on late-19th century steamship technology. Key systems include: brass-and-glass mechanical ship's chronometers (which log time automatically via ink on paper), hand-wound clockwork logging mechanisms for engine room status and door positions, pneumatic tube message systems between decks, wax-sealed written correspondence, and a single, centralized telegraph operator who logs all external communications by hand. There are no digital or electronic systems.
