twelve o’clock
There was a momentary silence ; and then I heard him tell his accomplice that he would go alone to look for the cab , and that she had better close the door and wait quietly in the passage till he came back . This was done . He walked out into the street . It was after twelve o'clock . No sound of a strange footfall was audible -- no soul was at hand to witness , and prevent , the coming struggle . His life was mine . His death followed him as fast as my feet followed , while I was now walking on his track .
