After I wrapped up the deal, I had a splitting headache and needed to go home. It was just after lunch, and since my car was in the shop, I had to beg a ride home with a colleague. The solitude of my home was just what I needed. My daughter, Sally, was at school and my wife wouldn't get home until after six o’clock or possibly later. I took a potent pain killer that my doctor had given me months ago for an injured back. It was probably a stronger pain killer than I needed, but I gulped it down with a swallow of water and crashed on the den sofa.
