midnight
The roof of the empty house adjoined mine along the back wing , but investigation showed that the trap-door across the low dividing wall was bolted underneath . There was nothing out of the ordinary anywhere , and so I assured Mrs. Klopton . Needless to say , I did not tell her that I had left the trap-door open , to see if it would improve the temperature of the house . I went to bed at midnight , merely because there was nothing else to do . I turned on the night lamp at the head of my bed , and picked up a volume of Shaw at random -LRB- it was Arms and the Man , and I remember thinking grimly that I was a good bit of a chocolate cream soldier myself -RRB- , and prepared to go to sleep . Shaw always puts me to sleep . I have no apologies to make for what occurred that night , and not even an explanation that I am sure of .
