twelve o’clock
I reached the house . ``` `` Madame la Comtesse is asleep , '' says the maid . ``` `` When can I see her ? '' ``` `` At twelve o'clock . '' ``` `` Is Madame la Comtesse ill ? '' ``` `` No , sir , but she only came home at three o'clock this morning from a ball . '' ``` `` My name is Gobseck , tell her that I shall call again at twelve o'clock , '' and I went out , leaving traces of my muddy boots on the carpet which covered the paved staircase .
