I packed my overnight case and sighed. I hated this, hated going anywhere far away from home during the heart of the winter. I was always scared that my car would break down in the middle of nowhere, during a snow storm. But I had to conquer my fear this particular frosty Friday afternoon. I had a call of duty. My old friend had a pressing need to see me today. He sounded desperate on the phone. He wouldn’t enlarge on his plight, just said that he needed to see me this very day, and that I could stay overnight, so I wouldn’t have to drive back in the dark.
