Charlotte, darling, Henry said to his wife, who was staring at im in gape-mouthed horror. Jassamine, beside her, was wided eyed. Sorry im late. You know, i think i might nearly have the sensor working- Will interrupted. Henry, he said, your on fire. You do know that, don't you? Oh, yes, Henry said eagerly. The flames were now nearly to his shoulder. I've been working like a man possessed all day. Charlotte, did you hear what i said about the sensor? Charlotte dropped her hand from her mouth. Henry! She shrieked. Your arm! Henry glanced down at his arm, and his mouth dropped open. Bloody hell!
