He sat stiffly for a moment. “I guess I can see why Bobby Mallory shows up at his worst around you. I was bragging to myself that I was going to show the lieutenant what a younger officer with sensitivity training could do with a witness like you, and I blew it in five minutes. Finish your story—I won’t criticize your methods.”

I finished my story. I told him I didn’t know how Chigwell had gotten hooked up with Jurshak and Dresberg, but that they’d forced him to come along tonight to look after Louisa. And that Ms. Chigwell was worried about him, so when I showed up with my crazy suggestion that we row up the Calumet and sneak up on the plant from the rear, she jumped at the chance.

“I know she’s seventy-nine, but sailing’s been her hobby since she was a kid and she sure handled her oar splendidly. So then we got here, and we had a lucky break—Jurshak went into the plant and Dresberg walked off to check on the people in the ambulance. Who was in it? Is that who shot at you guys when you showed up?”

“No, that was the sentry,” McGonnigal explained. “He tried making a run for it. Someone got him in the abdomen.”

I suddenly realized that Caroline Djiak didn’t know where her own mother was. I explained the problem to McGonnigal. “She’s probably roused the mayor by now. I should call her if I can get back into one of the offices.”

He shook his head. “I think you’ve done enough running around for one evening. I’ll send a uniformed man over to her house—then she can get an escort down to the hospital if she wants. I’ll run you home.”

I thought it over. Maybe I’d just as soon not include a close encounter with Caroline in the night’s strains.

“Could we go pick up my car? It’s down on Stony a half mile or so.”

He pulled out his walkie-talkie and summoned a uniformed officer—my pal Mary Louise Neely. She saluted him smartly, but I could see she was eyeing me curiously. So maybe she was human after all.

“Neely, I want you to drive Ms. Warshawski and me down the road to pick up her car. Then go to the address she gives you on Houston.” He sketched the situation with Caroline and Louisa.

Officer Neely nodded enthusiastically—it’s a break to be signaled out for a special assignment from among so many. Even though it was just chauffeuring duty, it gave her a chance to make an impression on a senior man. She trailed behind us as McGonnigal went to tell Bobby what we were doing.

Bobby agreed reluctantly—he wasn’t going to contradict his sergeant in front of me or a uniformed officer. “But you’re talking to me tomorrow, Vicki, whether you like it or not. You hear?”

“Yeah, Bobby. I hear. Just wait until the afternoon—I’ll be a lot more cooperative if I get some sleep.”
