“Joey Pankowski used to work at the Xerxes plant,” I continued, “but he died in 1985. Now there’s some question that Louisa Djiak, who also worked there, has a child whose father he may have been. That child is also entitled to a share of the settlement, but Ms. Djiak is very ill and her mind wanders-we can’t get a clear answer from her as to who the father is.”

“I can’t help you, young lady. I have no recollection of any of these names.”

“Well, I understand you took blood and medical histories from all the employees every spring for a number of years. If you would just go back and look at your records, you might find that-”

He cut me off with a violence that surprised me. “I don’t know who you’ve been talking to, but that’s an absolute lie. I won’t stand to be harassed and harangued in my own house. Now you get out right now, or I’ll call the police. And if you’re an officer of the court, you can explain that to them in jail.” He turned without waiting for a reply and marched from the room.

Clio Chigwell watched him leave, her scowl deeper than ever. “You’ll have to go.”

“He did the tests,” I said. “Why is he so upset?”

“I don’t know anything about it. But you can’t ask him to violate his patients’ confidentiality. Now you’d better leave, unless you do want to speak with the police.”

I got up as nonchalantly as I could under the circumstances. “You have my card,” I said to her at the door. “If something occurs to you, give me a call.”

A light drizzle had started to fall. I sat in the car staring at the windshield, watching the rain break up on the greasy glass. After a while I turned on the engine, hoping to coax a little heat from the noisy motor.

Was it the Pankowski name that had rattled Chigwell so? Or was it me? Had Joiner phoned him telling him to beware Polish detectives and the questions they bring? No, that couldn’t be right. If that was the case, Chigwell would never have agreed to see me at all. And anyway, Joiner wouldn’t know Chigwell. The doctor was almost eighty; he must have been long retired when Joiner started at the plant two years ago. So it had to have been the mention either of Pankowski or Louisa. But why?

I wondered with growing uneasiness what Caroline knew that she hadn’t bothered to tell me. I remembered in vivid detail the winter she had asked me to fight an eviction notice served on Louisa. After a week of running between courts and landlord, I saw an article in the Sun-Times on “Teens Who Make a Difference.” It featured a glowing sixteen-year-old Caroline and the soup kitchen she’d used the rent money to set up. That was the last cry for help I’d answered from her for ten years, and I was beginning to think I should have let it go for twenty.

I fished around on the backseat for a Kleenex and found a towel I’d used at the beach last summer. After wiping a peephole in the windshield I finally put the car into gear and headed for the expressway. I was torn between calling Caroline to tell her the deal was off and the elephant child’s ’satiable curiosity to find out what had rattled Chigwell so badly.

In the end I did nothing. When I had fought my way through the noontime Loop traffic to my office, messages from several clients awaited me-inquiries I’d let slide while I mucked around in Caroline’s problem. One was from an old customer who wanted help with computer security. I referred him to a friend of mine who’s a computer expert and tackled the other two. These were routine financial investigations, my bread and butter. It felt good to work on something where I could identify both problem and solution, and I spent the afternoon burrowing through files in the State of Illinois Building.

I returned to my office around seven to type the reports. They were worth five hundred dollars to me; since both clients paid promptly, I wanted to get the invoices into the mail.

I was rattling along on my old standard Olympia when the phone rang. I looked at my watch. Almost eight. Wrong number. Caroline. Maybe Lotty. I picked up the phone on the third ring, right before the answering service kicked in.

“Ms. Warshawski?” It was an old man’s voice, fragile and quavering.

“Yes,” I said.

“I want to speak to Ms. Warshawski, please.” For all its quavering, the voice was confident, used to managing people on the phone.

“Speaking,” I said as patiently as I could. I had missed lunch and was dreaming of a steak and whiskey.

“Mr. Gustav Humboldt would like to see you. When would it be convenient to schedule an appointment?”

“Can you tell me what he wants to see me about?” I backspaced and used white-out to cover a typo. It’s getting harder to find correction fluid and typewriter ribbons in these days of word processors, so I capped the bottle carefully to save it.

“I understand it’s a confidential matter, miss. If you’re free this evening, he could see you now. Or tomorrow afternoon at three.”

“Just a minute while I check my schedule.” I put the phone down and got Who’s Who in Chicago Commerce from the top of my filing cabinet. Gustav Humboldt’s listing covered a column and a half of six-point type. Born in Bremerhaven in 1904. Emigrated in 1930. Chairman and chief stockholder of Humboldt Chemical, founded in 1937, with plants in forty countries, 1986 sales of $8 billion, assets of $10 billion, director of this, member of that. Headquarters in Chicago. Of course. I’d passed the Humboldt Building a million times walking down Madison Street, an old no-nonsense structure without the attention-getting lobbies of the modem giants.

I picked up the phone. “I could make it around nine-thirty tonight,” I offered.

“That will be fine, Ms. Warshawski. The address is the Roanoke Building, twelfth floor. I’ll tell the doorman to look out for your car.”

The Roanoke was an old dowager on Oak Street, one of six or seven buildings bordering the strip between the lake and Michigan Avenue. All had gone up in the early decades of this century, providing housing for the McCormicks and Swifts and other riffraff. Nowadays if you had a million dollars to invest in housing and were related to the British royal family, they might let you in after a year or two of intensive checking.

I set a speed record for two-finger typing and got reports and invoices into their envelopes by eight-thirty. I’d have to forgo whiskey and steak-I didn’t want to be logy for an encounter with someone who could set me up for life-but there was time for soup and a salad at the little Italian restaurant up Wabash from my office. Especially if I didn’t have to worry about parking at the other end.

In the restaurant bathroom I saw that my hair was frizzing around my head from this morning’s drizzle, but at least the black dress still looked tidy and professional. I put on a little light makeup and retrieved my car from the underground garage.

It was just nine-thirty when I pulled into the semicircle under the Roanoke’s green awning. The doorman, resplendent in matching green livery, bent his head courteously while I gave him my name.

“Ah, yes, Ms. Warshawski.” His voice was fruity, his tone avuncular. “Mr. Humboldt is expecting you. If you’ll just give me your keys?”

He led me into the lobby. Most modem buildings going up for the rich these days feature glass and chrome lobbies with monstrous plants and hangings, but the Roanoke had been built when labor was cheaper and more skillful. The floor was an intricate mosaic of geometric shapes and the wood-paneled walls were festooned with Egyptian figurines.

An old man, also in green livery, was sitting on a chair next to some wooden double doors. He got up when the doorman and I came in.
