Four
o'clock
Madame locked the door , and amused herself with her own business , without minding me , humming little nasal snatches of French airs , as she smirked on her silken purchases displayed in the daylight . Suddenly it struck me that it was very dark , considering how early it was . I looked at my watch ; it seemed to me a great effort of concentration to understand it . Four o'clock , it said . Four o'clock ! It would be dark at five -- _ night _ in one hour ! ` Madame , what o'clock is it ?
