I tried to turn my attention to some problems that had come in the mail, including a notice of insufficient funds to cover the check of a small hardware store whose pilfering problems I’d solved a few weeks ago. I made a call that brought me no satisfaction and decided to pack it in for the day. I’d just slung my mail into the wastebasket when the phone rang.

An efficient alto told me she was Clarissa Hollingsworth, Mr. Humboldt’s personal secretary.

I sat up in my chair. Time to be alert. I wasn’t ready to go to him, but the shark wanted to swim to me. “Yes, Ms. Hollingsworth. What can I do for Mr. Humboldt?”

“I don’t believe he wants you to do anything,” she said coolly. “He just asked me to pass on some information to you. About someone named—uh—Louisa Djiak.”

She stumbled over the name—she should have practiced pronouncing it before phoning.

I repeated Louisa’s name correctly. “Yes?”

“Mr. Humboldt says he talked to Dr. Chigwell about her and that it is probable that Joey Pankowski was the child’s father.” She had trouble with Pankowski too. I expected better from Humboldt’s private secretary.

I took the receiver away from my ear and looked at it, as though I could see Ms. Hollingsworth’s face in it. Or Humboldt’s. At last I held it back to my mouth and asked, “Do you know who did the investigation for Mr. Humboldt?”

“I believe he interested himself directly in the matter,” she said primly.

I said slowly, “I think Dr. Chigwell may have misled Mr. Humboldt. It’s important that I see him to discuss the matter with him.”

“I doubt that very much, Ms. Warshawski. Mr. Humboldt and the doctor have worked together a long time. If he gave Mr. Humboldt the information, you may certainly depend on it.”

“Perhaps so.” I tried to make my tone conciliatory. “But Mr. Humboldt told me himself that his staff sometimes try to protect him from unfortunate events. I suspect something like that may have been going on in this case.”

“Really,” she said huffily. “You may work in an environment where people can’t trust each other. But Dr. Chigwell has been a most reliable associate of Mr. Humboldt’s for fifty years. Maybe someone like you can’t appreciate it, but the idea of Dr. Chigwell lying to Mr. Humboldt is totally ludicrous.”

“Just one thing before you hang up in righteous indignation. Someone misled Mr. Humboldt terribly about the true nature of the suit Pankowski and Ferraro brought against Xerxes. That’s why I’m not too confident about this last bit of news.”

There was a pause, then she said grudgingly, “I’ll mention the matter to Mr. Humboldt. But I doubt very much that he’ll want to talk to you.”

That was the best I could get from her. I frowned at the phone some more, wondering what I would say to Humboldt if I saw him. Fruitless. I locked up the office and drove up to the little hardware store on Diversey. They hadn’t wanted to talk to me on the phone, but when they saw I was prepared to be vocal in front of their customers they took me into the back and reluctantly wrote out another check. Plus the ten dollars handling for the bad one. I paid it directly into my bank and went home.
