Four o'clock
`` No , my dear boy , '' he continued , -- `` You ca n't catch it , And I ca n't fetch it , `` so you may as well take it easy and wait for the next one . '' `` When does the next one go ? '' inquired Ralph , looking up at the strange young man , but with his eyes still unaccustomed to the darkness of the room . `` Four o'clock , my cherub ; not till four o'clock . Going up on that train myself , and I 'll see you right through : -- `` Oh , sonny ! if you 'll wait and go with me , How happy and delighted I should be . '' Then the young man did a strange thing ; he took hold of Ralph 's arm , led him to the window , turned his face to the light and scrutinized it closely .
