A Rattling Ambush

I stalked out from beneath the dark console and hauled myself up to the bottom shelf of the bookcase, dragging my prize along. Tucked right between two heavy, dusty encyclopedias was an empty glass mug. A wicked thought struck me. I hooked my metallic ring right against the rim and dropped it inside—*CLANG-CHIME!* The sharp echo vibrated through the glass, loud enough to wake any phantom. I crouched behind the spine of a book, listening to the chime ring out across the quiet room. You'll never guess where the next noise comes from.
