midnight
`` What man ? '' enquired Emily . `` It was no man , lady , '' said Launcelot , who stood by , `` but the devil himself , as my comrade says . What man , who does not live in the castle , could get within the walls at midnight ? Why , I might just as well pretend to march to Venice , and get among all the Senators , when they are counselling ; and I warrant I should have more chance of getting out again alive , than any fellow , that we should catch within the gates after dark . So I think I have proved plainly enough , that this can be nobody that lives out of the castle ; and now I will prove , that it can be nobody that lives in the castle -- for , if he did -- why should he be afraid to be seen ? So after this , I hope nobody will pretend to tell me it was anybody .
