If you want to talk to me, I will be in the gazebo across from the Drake for ten minutes. If you don’t show, I’ll be on my way. Will Bobby Mallory sit on the truth for you?

V.I.

I sealed up my note in the envelope and addressed it to my uncle. Across the street, I entered the lower lobby of the Drake, where there’s an arcade of shops. A bellman was standing near the stairs leading to the Drake’s main lobby. I gave him a five and asked him to deliver the envelope at once. Then I walked quickly through the arcade to the hotel’s north entrance.

It was 1:23 when I handed the letter to the bellman. Assume Peter was in his room. Assume the bellman delivered the envelope right away. Peter would call Dornick … or Alito … or Les Strangwell. Something should happen within twenty minutes.

Just across the street from the Drake is a little park, a triangle made by the hotel, Michigan Avenue on the left, and Lake Shore Drive as the hypotenuse. Beyond the drive lie some of the city’s most beautiful sand beaches. This time of year, the Oak Street Beach was packed with tourists, tanners, swimmers, and volleyballers, but the triangular park was essentially empty. A homeless man was asleep on a patch of grass outside its gazebo.

I walked along the row of cars parked on the south side of the triangle. Only one had someone sitting inside. There was a service van in front of one of the condos, and it could have held a surveillance team, but I didn’t think Dornick or Strangwell would feel the need to keep that sophisticated of a watch on Peter.

I walked back to Michigan Avenue, which was filled with shoppers and tourists. A trio of black youths banged homemade drums on the corner.

A tunnel goes under the avenue, but I crossed at street level. I was in the company of a woman who had a leash with a dog at the end of it in one hand and a cellphone in the other that was glued to her ear. A nanny with a baby buggy, also on a cellphone, was behind me. I felt reassuringly anonymous, just one more person in a ball cap enjoying the end of summer.

I sat on a bench in a bus stop on the far corner and watched the park. An elderly man with a toy poodle shuffled over from one of the condos near the hotel. The dog sniffed at late-blooming orange flowers while the man stared vacantly into the distance. A hard-muscled young woman jogged past the gazebo, down a ramp leading under Lake Shore Drive and to the beach. A few bicyclists emerged on the return route.
