I followed with lagging step , and thoughts busily bent on discovering a means of extrication ; but he himself looked so composed and so grave also , i became ashamed of feeling any confusion : the evil - if evil existent or prospective there was - seemed to lie with me only ; his mind was unconscious and quiet
可是他显得那么镇定，那么严肃，使我反而为自己的慌乱而感到羞愧了。如果说心中有鬼不管是现在还是将来那只能说我有。他心里十分平静，而且全然不觉。
