o'clock
Madame Wachner had summed up Count Paul very accurately . At last there came the sound of a carriage in the quiet lane outside . `` Fritz ! Go and see if that is the carriage I ordered to come here at nine o'clock , '' said his wife sharply ; and then , as he got up silently to obey her , she followed him out into the passage , and Sylvia , who had very quick ears , heard her say , in low , vehement tones , `` I work and work and work , but you do nothing ! Do try and help me -- it is for your sake I am taking all this trouble ! '' What could these odd words mean ? At what was Madame Wachner working ?
