I dressed for the day in jeans and running shoes. Since the cops had trailed me to St. Remigio’s, I was going to leave my car at my office; I wanted to be able to move fast through the city. The dogs got the shortest of walks. I left them with Mr. Contreras, then drove to my office, where I went inside just long enough.to check my messages. No tox report. No messages that couldn’t wait. I put a fresh battery pack in my cell phone and took off.

On my way to the El, I turned abruptly into a bakery, then stuck my head out the door. No one had halted on the walk behind me. I bought a ginger scone and a bottle of orange juice, picked up the morning papers and hurried to the train.

The detective’s life is harder on public transport. The train was so packed I had to stand. I couldn’t eat or read and when I got out, I was still two miles from my destination, since the line to the Gold Coast is different from the one near my office. At Division, I flagged a cab to the corner of Banks and Astor. When I got out, a young woman swung into the backseat

before I finished paying-it was eight-ten, the time when aggressive young lawyers and financiers race to their desks.

I crossed the street to where I could see the Bayard apartment. With the Herald-Star in front of my face, I called up and asked for Renee. She was still inside; I hung up just as she came to the phone. I made a little eyehole in the Herald-Star; while I ate my scone, I watched nannies and mothers hurry their children to school. I also got to see a ferocious competition for cabs among the work-bound-including a shoving match between two women. The one I was silently betting on lost.

Renee Bayard could probably have won a battle for a taxi, but she didn’t have to fight: a dark sedan was waiting in front of the Banks Street apartment. At eight-forty-eight, the driver climbed out and stood by the rear door. At eight-fifty, Renee came through the front gate, a commanding figure in navy wool. Her son was with her. The driver tucked Renee into the backseat, but Edwards walked over to State Street and headed north.

He could be going anywhere, but the Vina Fields Academy lay in that direction. If he was going to pick up books or lesson plans for Catherine, Elsbetta would know about it, and I couldn’t use that as my pretext for getting into the building. I bit my lip in indecision, but finally crossed the street and rang the lower apartments, starting with the first floor. No one answered there, the second floor hung up on me, but the third floor buzzed me in as soon as I said I was from the Vina Fields Academy. They buzzed me again through the inner door. Just to minimize suspicions in the building, I rode to the third floor, said I was there for Catherine Bayard and was directed to five. So far, so good.
