midnight
I sha n't show up until a Sikh named Narayan Singh tells me that a certain Noureddin Ali is in there . He 's the bird I 'm after . He 's a dirty little murderer , and I 'm going to be right pleasant to him . `` You may have to sit in the place all day waiting for me ; but wait until after midnight if you must . Sooner or later Noureddin Ali is bound to show up . I shall be hard after him . If they offer you food , take it .
