four o'clock
Where have you sprung from , and when did you arrive ? '' `` I only got in yesterday after sundry adventures which I will tell you about presently . When did you arrive from the front ? '' `` I came down a few days ago on a week 's leave on urgent family business , '' the young man laughed , `` and I am going back again this afternoon by the four o'clock train . '' `` Stay till ten , '' Vincent said , `` and we will go back together . There is a special train going through with ammunition , and as everything will make way for that it will not be long behind the four o'clock , and likely enough may pass it on the way . There is a horse-box attached to it , and as I only take one horse there will be room for yours . ''
