about nine o'clock
It was only one of twenty little things I remembered . Stayed in the back of my head , waitin ' to tie up with something else . `` Come Tuesday -- week ago to-day and my afternoon off . I was comin ' home early , about nine o'clock . I 've got front door privileges , but I generally use the servants ' entrance just the same . Right ahead of me , a green automobile with one of those limousine bodies drove up to the front door . It 's dark down in the area by the servants ' entrance .
