Passport Mystery

James Armstrong left London to join his wife, Alicia, after her grandmother had a bad fall and called for her granddaughter to help in a southern coastal city.
James was working at that time on a passport scam involving his wife without her knowledge. Percy Gray is the father of the surgeon who operated on Alicia's grandmother's arm who called his father, a retired police detective, to have a look at the situation that caused the fall, thinking foul play had played a part, so fate stepped in to introduce Percy Gray and James Armstrong to solve the granny's fall affair.
The passport scam was also solved by James, with help from Alicia. It had caused some angst between them when Alicia was told of her part in the passport affair, but she eventually could see why James had not told her. He now had to make up his mind whether to stay in London for his job or take up Percy Gray's offer as a partner in a private investigation business. Granny would be incapacitated for several years, and Alicia wanted to help her out, so they decided to stay in the southern coastal city permanently and take up the investigations partnership.
