midnight
As he glanced timidly up , and met the Jew 's searching look , he felt that his pale face and trembling limbs were neither unnoticed nor unrelished by that wary old gentleman . The Jew , smiling hideously , patted Oliver on the head , and said , that if he kept himself quiet , and applied himself to business , he saw they would be very good friends yet . Then , taking his hat , and covering himself with an old patched great-coat , he went out , and locked the room-door behind him . And so Oliver remained all that day , and for the greater part of many subsequent days , seeing nobody , between early morning and midnight , and left during the long hours to commune with his own thoughts . Which , never failing to revert to his kind friends , and the opinion they must long ago have formed of him , were sad indeed . After the lapse of a week or so , the Jew left the room-door unlocked ; and he was at liberty to wander about the house . It was a very dirty place .
