Sherlock: The Riddle of the Crown Jewels (1988)

Watson has forty-eight fictional hours to recover the stolen jewels, following riddles through Victorian London while some opportunities depend on the time of day. This is a trail of literary and physical puzzles more than a household of suspects to interrogate. WAIT UNTIL helps with timing, and the built-in HINT menu can reveal increasingly direct help. SAVE and RESTORE remain useful; UNDO depends on the interpreter's support. Keep the supplied material handy, and choose this for a clock-bound Holmes excursion rather than a freely argued accusation.
