The observatory lamp

An original fiction passage set in the nineteenth century.

Clara pushed open the observatory door. It gave a long, complaining creak, and the darkness beyond seemed to lean towards her. She had come only to fetch the brass key her uncle had forgotten, yet a narrow bar of light lay across the floor. At its end, the great telescope pointed towards the shuttered window.

She stopped. The lamp on the desk was still warm, though the room had been empty when she left it. Clara called her uncle’s name. Her voice sounded small beneath the curved ceiling. Then a silver point appeared between the shutters. It trembled once and vanished.

She crossed the room. The telescope’s eyepiece was turned towards her, not the window. On the desk lay a note in her uncle’s careful hand: “Look up.” Clara lifted her eyes to the dome. A panel had been opened above her, and the night sky filled the gap. The bright point returned, steady now. She forgot the key in her hand.
