Jack and Mr. Grin

Jack Orange is a twentysomething guy who works at a place called The Tent packing dirt in boxes and shipping them off to exotic, unheard of locales. He thinks about his girlfriend, Gina Black, and the ring he hopes to surprise her with. But when he returns home one day, Gina isn't there. He receives a strange call from a man who sounds likes he is smiling-- Mr. Grin. He says he has Gina. He gives Jack twenty-four hours to find her--Publisher's description.
