1923 Season 1 - Threesixtyp ✨ ✨

The snow came early that year, burying the Gallatin Valley in a silence that felt less like peace and more like a held breath. In a cramped, clapboard office above a saloon, Arthur “Artie” Pendergast wasn't listening to the wind. He was listening to the tick-tick-buzz of a Western Electric telegraph key, but the rhythm was wrong.

Spencer glanced at the brass gear in his palm. “You know how to fix it?”

Artie had built the decoder—a clumsy, brass-and-copper contraption he called the "Threesixtyp" because its three rotating discs mapped letters in 360-degree permutations.
