Lawfully Wedded by Mistake

One clerical error, and I'm suddenly wedded to the man my twin agreed to marry by mail-order proxy. 

I just want to take photos and be the best crime photographer in my field. I have no interest in dating or marriage. Then this happens! And I'm somehow "married" to some guy I don't know. Except I do. He's a cop in one of the towns I interviewed in this past year. And they've just hired me. 

What are the chances? In my life, pretty good. And since my name is Murphy, the law always applies.
