 Now to work. First, an investment. $10.95 for a pair of binoculars. Nothing fancy, but good enough. Magnification, three and a half times. Very fine for seeing Penny Cullen sitting on a bench watching the ocean. That evening, get to the waterfront sometime before six. Find a spot that overlooks a bench to the left of a statue of a dying man. And wait. At quarter of six, a vendor pedals by the bench on a bike. He's selling ice cream.
