two o'clock in the morning
`` The boulevard is watched . No one can enter the room except by this way . So there is nothing to fear . '' At two o'clock in the morning a car stopped outside the house , and one of the manservants , who must have been waiting in the kitchen , hastened to the front door . Perenna switched off the light in the passage , and , drawing the curtain slightly aside , saw Mme. Fauville enter , followed by Silvestre . She went up . The lights on the staircase were put out .
