I was a surgeon. I was on duty at the hospital on Christmas Eve when an ambulance rolled into my ER with a man and a woman, both completely naked, pulled from a hotel room. My colleagues were all singing their praises. "Look at that couple. Even staring death in the face, they wouldn't let go of each other's hands." "They say true love shows up when the going gets tough. This has to be the real deal." But I stood there frozen, my blood running cold, because I couldn't believe my eyes. That man was my husband of seven years, Alex Mitchell. And that woman? My best friend of two decades, Claire Bennett.
