On my way in to the office I stopped off at the market. I needed to replace the bug-infested foodstuffs I’d discarded on Monday. I wasn’t likely to cook or bake, but my barren shelves looked pitiful. I stocked up on flour, cornmeal, cereal, and crackers, both graham and saltines, if you really want to know. I also bought baking soda and a container of baking powder. I’d noticed, as I tossed the old one in the trash, that the “best if used by” date on the bottom of the tin was March 1985. On a roll by then, I bought dried bow-tie pasta and long-grain rice, along with cans of tomato sauce, tomato paste, and diced tomatoes with onion and basil. I was shopping only to give my beleaguered brain a rest. I needed a new game plan and I wouldn’t come up with one if I tried to tackle the problem directly.

I moved to the next aisle, piling tissue boxes, rolls of paper towels, and toilet paper in my cart. I had my hand on a container of liquid detergent when a possible solution occurred to me. I finished my shopping, paid for my groceries, and stowed everything in the trunk of my car. Then I slid under the wheel and took my notebook out of my shoulder bag, leafing through the pages until I found the address Sanchez had given me for the McNally Pet Hospital on Dave Levine Street. At the back of my mind, I’d been playing a little game of “suppose” and “what if” in my quest to find Walker’s dad. I’d thought, What if, on his retirement, Dr. McNally had sold his practice to another veterinarian? The new vet might well know his current whereabouts.

I fired up my Mustang and pulled out of the lot. I hung a right on Chapel and drove the length of it until I reached the dead end at Miracle, where I turned left for half a block. This put me at Dave Levine Street, six blocks from the point at which it split from State. The address I wanted had to be somewhere to my left. I turned and continued at a greatly reduced speed until I reached Solitario Street. On the far side of the intersection, in a seven-tenant strip mall, I spotted Mid-City Cat Clinic with an address that matched the one Sanchez had given me. I snagged the only parking place available and sat for a moment, hoping the gods would be merciful. A wooden cutout of a Puss in Boots pointed at the clinic door, where the names of two veterinarians were stenciled on the pane—Stephanie Forbes, DVM, and Vespa Chin, DVM.
