midnight
``` Your name is not unknown to fame , ' said the Baron , ` I have heard of it . ' -LRB- The Knight looked haughtily . -RRB- ` But why , since my castle is known to entertain all true knights , did not your herald announce you ? Why did you not appear at the banquet , where your presence would have been welcomed , instead of hiding yourself in my castle , and stealing to my chamber , at midnight ? ' `` The stranger frowned , and turned away in silence ; but the Baron repeated the questions . ``` I come not , ' said the Knight , ` to answer enquiries , but to reveal facts . If you would know more , follow me , and again I pledge the honour of a Knight that you shall return in safety .
