This is a gangster epic that combines historical conspiracy, steampunk and mysticism. The story is set in the British industrial city "Steel City" in 1919, focusing on the Kirwan family - a gang empire based on smuggling arms, casinos and dock control. The leader of the family, **Edwin Cowan**, is as cold and meticulous as a precision pocket watch, while his younger brother **Linus** and the executioner **Marcus** are transformed into violent gears, jointly maintaining the bloody rule of the family.
The work uses a cold and hard writing style to outline the gunfire and gears in the steel rain and fog, and uses the cloak of the gangster epic to explore the symbiosis and alienation of human nature under the craze of the industrial revolution.
