Sitting Room Fireplace Mantel

Data reaches to the fireplace mantel in the twilight-lit sitting room of the Sherlock Holmes holodeck program and picks up a box of matches. He tosses the box to the Gentleman, who catches it left-handed against program rules. Geordi spots the glitch from this interaction. The mantel, a carved wooden shelf above the dormant fireplace, holds simulation props amid leather chairs and gas lamps, its surface catching faint light as tension builds.
