He always went into drinking houses and billiard saloons , and once into a place where they say the worst kind o ' gambling is allers -- I mean always -- going on . But he knew me by sight , and I was afraid he would ask me about that letter which I did n't deliver for him . So I had to follow him a good piece behind ; and sometimes I lost track of him . Then , again , he would keep a tramping round from one drinking place to another -- but never getting drunk that I could see -- till twelve or one o'clock at night . By that time I felt I ought to go home , and so I never tracked him to his lodgings , if he has any . But it 's my belief he travels in the night , and sleeps in the daytime , like the cats . '' `` Good , so far , '' said Marcus .
