midnight
-- I spent the evening quietly with Carrie , of whose company I never tire . We had a most pleasant chat about the letters on `` Is Marriage a Failure ? '' It has been no failure in our case . In talking over our own happy experiences , we never noticed that it was past midnight . We were startled by hearing the door slam violently . Lupin had come in . He made no attempt to turn down the gas in the passage , or even to look into the room where we were , but went straight up to bed , making a terrible noise .
