three o'clock in
the morning
The house will be blown up at three o'clock . Yes , yes , I swear it will . Ten days after the fourth letter means now , because there has been a ten days ' delay in the delivery of the letters . It means now , at three o'clock in the morning . Remember what was written on the sheet which Deputy Chief Weber handed you this morning : ` The explosion is independent of the letters . It will take place at three o'clock in the morning . ' At three o'clock in the morning , to-day , Monsieur le Préfet ! ''
