Rain polished the courthouse steps while Inspector Vale examined the corpse beneath the blindfolded statue of Justice at midnight alone. A silver teaspoon protruded from the judge's pocket, engraved with tomorrow's date and stained by raspberry jam from somewhere nearby. No footprints crossed the marble, yet wet roses formed an arrow pointing toward the locked records room downstairs beside them. Vale counted twelve petals, twelve chimes, and twelve nervous witnesses pretending not to recognize the dead man's crimson gloves tonight. Then the courthouse clock struck thirteen, and every electric light vanished except one glowing inside the victim's open mouth below.
