three o'clock
Rolfe stood by a window and read quietly . This first report told him little that he had not already learnt , but there were a few details of the suicide . Frothingham , it appeared , always visited the office of _ Stock and Share _ on the day before publication . Yesterday , as usual , he had looked in for half an hour at three o'clock ; but unexpectedly he came again at seven in the evening , and for a third time at about eleven , when the printing of the paper was in full swing . ` It was supposed by the persons whom he then saw that Mr. Frothingham finally quitted the office ; whether he actually left the building or not seems to remain uncertain . If so , he re-entered without being observed , which does not seem likely . Between two and three o'clock this morning , when _ Stock and Share _ was practically ready for distribution , a man employed on the premises is said , for some unexplained reason , to have ascended to the top floor of the building , and to have entered a room ordinarily unused .
