[ WP ] A man invents time travel in order to find a cure for his sick wife and succeeds , only to find out he ca n't go back

*I've taken the title and gone my own way with it a bit, I hope that's ok. It also did n't turn out quite the way I wanted it. The character gives up a bit too easily and the dialogue feels a bit clumsy. I might come back to edit it later, if I have some ideas. *

 The crowds shifted uneasily around the terminal. The loud bustling pounded in the ears of Dr Hadley as he sat nervously, clutching the locked briefcase to his chest. He held in his hands the culmination of many years of painstaking work. She would live. 
 
 It had taken several years and all of his life savings to develop the technology to travel forward in time. As soon as he arrived, his time machine was seized and destroyed under some obscure law. Unperturbed, he just worked on trying to cure the disease. He would worry about returning when he had reason to. He hadn ’ t dared to look her up in case he was unsuccessful and all he found was a miserable grave somewhere. 
 
 The tannoy system blared above the crowd “ Would all passengers destined for 2013 please report to gate 5. ” 
 
 Hadley stood up gingerly, careful to keep the briefcase stable to avoid disturbing its priceless contents. Pushing his way through the crowds, he got in line at gate 5 and waited his turn. 
 
 “ Good afternoon, sir ” the attendant exclaimed jovially, as Hadley approached his desk. “ Boarding pass please ” 
 
 “ I.. I ’ m afraid I don ’ t have one, but I absolutely have to be on this vehicle ” Hadley said, weakly. 
 
 “ I ’ m sorry sir, no boarding pass, no entry. ” The boarding attendant frowned at Hadley; he had customers like this all the time. “ Please report to the ticket office and you ’ ll be able to purchase a ticket for the small fee of five hundred thousand dollars. ” 
 
 “ I haven ’ t got the money.. “ 
 
 “ Then I ’ m sorry, sir, but you aren ’ t getting past me. ” The attendant motioned to the next passenger in the line, who barged in front of Hadley, pushing him out of the queue. 
 
 Hadley turned and left the terminal building. Maybe he would go looking for that grave after all.
