It was time to go to Tyreâs workplace. Twenty minutes later I took a cab up to the main Department of Parks administration building, which stands just inside the Fifth Avenue entrance of the Zoo. I found Frank Ardmore on the second floor of the building in a small office. He was not happy to see me. âI donât understand. Are you a cop?â âNo. Iâm just temporarily attached to a special unit that is investigating Jack Tyreâs murderâand his brotherâs.â âWell, I spoke to the cops for hours. I told them everything I knew. Which wasnât much. Look, the man worked right next door to me for a long time. We were friendly. We talked together all the time. But not after work. He went his way and I went mine.â âDid you ever see these?â I asked. Frank Ardmore stared down at the small leaf bouquet I held in my hand. âWhat the hell is that?â he asked. He kept on adjusting his stubby tie. He had a whole raft of pencils and pens in his shirt pocket, which seemed about ready to fall out. âThree leaves tied together with a twistum.â I opened the red twistum and laid the three leaves on my arm. He shook his head in confusion. âDid Jack Tyre collect leaves?â âAre you kidding? I donât know what you mean. Collect leaves? Thousands of tons of leaves are collected in this park in the fall. Jack didnât work in that department. Did he like trees? How the hell should I know? Could he identify trees? Probably. Most people who work in parks with a lot of trees can identify them. Even I can do that.â He leaned over and pointed. âThat is a ginkgo leaf. That is an oak leaf. And that . . .â He paused. He picked up the third leaf. âAnd that looks like a leaf from a Chinese maple on the Seventy-Second Street footpath, which by the way, is one of the oldest living trees in the park.â I re-bound the leaves. He was not a friendly man. Not at all. I stared at him. There was something strange about his discomfort in my questions. âIs there anything about Jack Tyre that you forgot to tell the police?â âLike what?â âYou tell me.â âYeah. He didnât like Chinese food,â Frank Ardmore replied sarcastically. âThank you for your help,â I replied, equally sarcastically, and started to walk away. âWait a minute. If you want to find out about leaves, why donât you see Georgina Kulaks. Sheâs in charge of tree maintenance around here.â âWhere do I find her?â âI think theyâre working on that European beech near the bow bridge, on the south end of the lake.â I walked out of the administration building and headed uptown and west through the park. At Bethesda Fountain I cut into one of the footpaths and headed toward the lake. It was a beautiful day. People were walking arm in arm. There were dogs and baby carriages and kite fliers. As I walked down the grassy knoll to the bow bridge, I saw a small team of workers near a massive low-crowned tree. That must be the European beech. When I got closer, I realized they were all men. Then I caught sight of a woman standing about twenty yards away from the group, closer to the lake. She was holding a clipboard and staring out across the lake. I walked up to her. She nodded in a friendly fashion. âAre you Georgina Kulaks?â I asked. She nodded and waited, smiling. She was a short, slight woman with brown hair pulled back. She was wearing regulation parks-department pants and a sweatshirt. Her face was lined. âMy name is Alice Nestleton. Iâd like to ask you a few questions about Jack Tyre.â Her eyes opened wide in horror. They stared down at my hand. I realized I was holding the bunch of leaves in plain view. Her face seemed to crumble . . . to dissolve. She turned away from me quickly and knelt down. The sobs seemed to explode from her
