THE GOLD OF PRAGUE

Master Ottokar Brandt, the court alchemist, claims he has turned copper into gold. Tomorrow at noon he will do it again before Emperor Rudolf II, who has promised him a pension and a noble title in return.

You are an apprentice in the laboratory. Tonight Brandt is out at dinner. On the workbench: his grimoire, two golden ingots, and a note slipped under your door: “It isn't magic. It's theft. Prove it before noon. — A friend at the Treasury”

Four rooms, one investigation: each experiment gives you a result you will need in the next one. Everything goes into your case file.
