The moment Joanna told me she was engaged, I had this awful feeling that something was wrong. We used to speak on the phone every day. Growing up I spent more time at her house than I did at my own. I’d always imagined what it would be like to see her get married, and now I didn’t even know her fiancé’s name. She asked me to come and meet Mark and I intended to tell her to slow down. You can’t know someone for a month and be sure that you want to spend the rest of your lives together. When I got to Joanna’s front door, only Mark was there. He was charming and gorgeous and nothing but nice to me, and I started to understand. And then he told me that Joanna was missing.
