four o'clock
But it was Sunday afternoon before the storm broke . Wolf was at church when Norma wakened , and as she dressed she meditated a trifle uneasily over this departure from their usual comfortable Sunday morning habit . She breakfasted alone , Wolf and his mother coming in for their belated coffee just as Norma , prettily coated and hatted and furred , was leaving the house for the ten-o'clock Mass. . They did not meet again until luncheon , and as Wolf had explained that he must leave at four o'clock for Philadelphia , Norma began to think that this particular visit would end without any definite unpleasantness . However , at about three o'clock , he invited her to walk with him to the station , and join his mother later , at Rose 's house , in New Jersey , and Norma dared not refuse . They locked the apartment , and walked slowly down Broadway , as they had walked so many thousand times before , in the streaming Sunday crowds . Before they had gone a block Wolf opened hostilities by asking abruptly : `` Where did you go to church this morning ? ''
