What is the mood of the following excerpt?
“Walking on tiptoe and shading the candle, they went first to the dining room. There wasn’t a stick of furniture to be seen. Bare walls and mantelpieces, and an empty floor stared at them. They felt as if everything in the room disliked them being there. Shadows flitted right and left from the candle-flame and something seemed to be at their back, watching, waiting" (Blackwood 4).
