a quarter past eleven
Your door is probably shut by ten ? '' she asked . `` By eleven , '' answered Silas . `` At a quarter past eleven , '' pursued the lady , `` leave the house . Merely cry for the door to be opened , and be sure you fall into no talk with the porter , as that might ruin everything . Go straight to the corner where the Luxembourg Gardens join the Boulevard ; there you will find me waiting you . I trust you to follow my advice from point to point : and remember , if you fail me in only one particular , you will bring the sharpest trouble on a woman whose only fault is to have seen and loved you .
