About six o'clock
I went back to the bed and tried to sleep , but I could n't . I could have killed Twigg ; but there was n't any way to do it . He kept on reading and smoking . About six o'clock he said : `` This is quite a yarn , is n't it ? Somehow I never seemed to find time for Marryat when I was a boy . You 've read this , of course ? '' `` Yes , '' I muttered .
