I put out the light. Outside the window, a few cold stars shimmered in the blue-black sky. No one should be knocking at my door at this time of the night, I thought. And even suppose someone really were doing so, it must surely be an ignorant good-for-nothing—waking people up like this yet giving no reply. Yet these musings were cut short again—this time, the sound from outside my door was a rumbling, like the sound of thunder. Naturally, it couldn’t be the thunderous din of mosquitoes. Certainly, there were mosquitoes around, but they were all hidden in dark corners, long since having lost any impetus to make such a sound. I knew too that it wasn’t real thunder, for it was still too early for that just then. I turned over under my quilt, pressing my left ear firmly to the pillow, suspecting that this rumbling was nothing more than a ringing in my ears.
