The Blue Light

I'm not sure about the narrator, but the ghost fell silent as a result of shock and embarrassment.

On reaching the room occupied by the twins, which I should mention was called the Blue Bed Chamber, on account of the colour of its hangings, he found the door just ajar. Wishing to make an effective entrance, he flung it wide open, when a heavy jug of water fell right down on him, wetting him to the skin, and just missing his left shoulder by a couple of inches. At the same moment he heard stifled shrieks of laughter proceeding from the four-post bed. The shock to his nervous system was so great that he fled back to his room as hard as he could go, and the next day he was laid up with a severe cold.
