Pat, the ghost of a scoutmaster with an arrow through his neck, squints at it. "We’ve pressed every other floor in this house for decades. Basement, ground, first, second, attic. Never seen that one before."

The other ghosts crowd around in the drafty hallway. The elevator—installed in 1927 by a previous owner, a reclusive film collector—has always been temperamental. But tonight, the full moon through the warped window of the landing casts a silver line directly onto the BD9 button.

At the end of the corridor: a small screening room. Nine velvet seats. A projector. And on the wall, a single title card in gilded letters:

"Or," says Thomas, the lovesick Romantic poet, "we could finally learn what BD stands for."

She presses it.

It looks like you're referencing a specific file or episode label — "ghosts s02e12 bd9" — which suggests the British sitcom Ghosts (or possibly the US version), Season 2, Episode 12, with "BD9" likely indicating a Blu-ray rip or disc image quality.
