six o'clock
Miss Martin was not to be spoken to except in Dove 's company . There was only one person who could assist him , if she would , and that was Madeleine Wade . He called to mind the hearty invitation she had given him , and reproached himself for not having taken advantage of it . One afternoon , towards six o'clock , he rang the bell of her lodgings in the MOZARTSTRASSE . This was a new street , the first blocks of which gave directly on the Gewandhaus square ; but , at the further end , where she lived , a phalanx of redbrick and stucco fronts looked primly across at a similar line . In the third storey of one of these houses , Madeleine Wade had a single , large room , the furniture of which was so skilfully contrived , that , by day , all traces of the room 's double calling were obliterated . As he entered , on this first occasion , she was practising at a grand piano which stood before one of the windows .
