Your master vanished on judging day. The machine still works. Someone wants it not to.
The Crown Exhibition is the grandest day in Candlemere: glass halls, brass wonders, and a Royal Warrant
that can make a workshop's fortune. Your master's invention is crated in Hall C, and judging begins at four.
Your master, however, is gone — bed unslept, door locked from outside, one strange drawing left behind. Find him,
protect the machine, and outwit rival guilds, a restless prince, and an inspector who thinks you know more than you
are saying. The clock is already ticking.
