London, 1871. The spectre of communism might be haunting Europe, but Karl Marx’s demons are far more mundane. Watched by a spy, chased by debt collectors, harassed by his family (legitimate and not), and rescued repeatedly from financial ruin by Friedrich Engels, a single madcap day is the backdrop for a run of misadventures and mistakes. Marx might have envisioned an economic system that would restore order and equality to the workers of the world, but his own affairs are in chaos. Amidst this storm in a teacup, can he find an hour to write?
