Run a cheese cave as its mouse cellarmaster. Wheels age in real time: sell them young, or wait and they are worth up to five times as much. Nothing ever spoils, so leaving is always safe. Hire apprentices, hand over cheeses for the notes at the grating, dig rooms for cheeses that take an afternoon, a night or three days, win rosettes at the County Show, and listen to 1910s gramophone records while you wait. Drawn in pen and ink, like a 1920s magazine.
