nine o'clock in the
evening
` My master would have it so . ' ` But tell us then what Master Cardillac was doing out in the streets at so late an hour ? ' ` That I can not say . ' ` But you have never before known him to leave the house after nine o'clock in the evening , have you ? ' Here Olivier falters ; he is confused ; he sighs ; he bursts into tears ; he protests by all that is holy that Cardillac really went out on the night in question , and then met with his death . But now your particular attention , please , Mademoiselle . It has been proved to absolute certainty that Cardillac never left the house that night , and so , of course , Olivier 's assertion that he went out with him is an impudent lie .
