 I finally caught sight of him a couple of blocks later. He was headed south along a back street. I trailed him all the way out to 47th Avenue. Sand dunes, oil wells, a scattering of houses. Then I saw him duck into some shadows, so I waited. About ten minutes later, a big Cadillac came along, cruising slowly. As it reached the corner, someone inside flicked out a package, and then the car disappeared into the night. Frank Jessup suddenly darted out of the shadows, scooped up the package, and came running straight toward me.
