two o'clock in the morning
`` We 're getting somewhere ! '' It was a railroad train on the other side of a valley , but they did not reach the track . The highway curved away from it . At two o'clock in the morning they saw electric lights . The highway became suddenly passable . Presently they ran into the still , silent streets of a slumbering town -- Serrai -- an administrative center for this part of Greece . They threaded its ways while Coburn watched for a proper place to stop .
