The echoes of laughter and whispered tales of the supernatural had been the evening's prelude. In the dim twilight, shadows played tricks upon the senses, creating a realm between imagination and reality. Halloween at Trinity General School was a night of transformation, where familiar faces donned masks of mystery.
