midnight
I watched him for a while and saw that he was studying that queer little book which so deeply affected him , and I again heard him utter those despairing words : `` God forbid ! God forbid ! '' ~ ~ ~ I went to bed at a little after ten and tried to sleep , but the city-wide excitement seeped into my room and kept me tossing from the thrusts of nightmares . At midnight Carse came up and stopped just outside my door , obviously listening to determine whether I was asleep . The silence was uncanny for a moment ; then I heard a sharp metallic clicking and he went on to his room . After he had closed his door , I swept my sheet aside and went to my own door . Carse had locked it from the outside !
