Anomaly in the Archive

A sudden tremor echoed from the stack of oversized volumes at the shelf's edge. You mentioned stories of restless spirits bound in ink. I proceeded cautiously, keeping low beneath the shadow of a heavy encyclopedia. The top tome—an aged, cloth-bound atlas—shivered once more. I reached the seam and braced my shoulder against the cover, levering it open a fraction. Inside, no spectral force awaited. A mechanical copper clockwork bookmark had slipped loose between the thick pages, its exposed escapement wheel still ticking and vibrating against the binding. I clamped the gear mechanism still. Anomaly resolved.
