In the end, neither the drive nor the restitching was as big an ordeal as I’d feared-the former because the main streets were so thick with Saturday shoppers that even Lotty had to go slowly. At her clinic, a storefront about a mile west of my apartment, in a polyglot neighborhood on the fringes of the North Side’s new construction, she shot Novocain into my shoulder. I felt a faint tugging as she cut the old stitches and put new ones in, but either because of her skill or the anesthetic I could actually move my arm pretty easily when she finished.

With Lotty lying back in an easy chair in her office, we finally got to April Czernin’s woes. Lotty listened intently, but shook her head with genuine sorrow over the limited help the Czernins could get.

“The insurance really only covers ten thousand dollars of her care? That’s shocking. But it’s so typical of the problems our patients face these days, being forced to make these choices of life and death because of what the insurance does or doesn’t pay.

“But as for your girl, we can’t take her on as a Medicaid patient, because she’s not indigent; as soon as the billing department finds out she has insurance, they’ll do exactly what the university did, call the company and be told the policy won’t cover the defibrillator. The only thing I can suggest is that they try to get her involved in an experimental trial, although the treatment for Long QT is pretty standard at this point, and it may be hard to find a trial group anywhere they can afford to travel to.”

“I think Sandra Czernin would go anywhere if she thought it gave April a fighting chance. Lotty, I keep worrying that I should have noticed something before she collapsed.”

She shook her head. “Sometimes there may be a fainting spell-you say the mother reports one last summer-but often these collapses come out of the blue, with no warning.”

“I’m afraid to go to school Monday,” I confessed. “I’m afraid to ask any of these girls to run up and down the court for me. What if there’s another one with some time bomb ticking in her chest or brain?”

Morrell squeezed my hand. “Tell the school they have to test the girls before you’ll continue the program. I’m sure the moms would agree, at least enough of them to force the school to take action.”

“Bring them up to the clinic and I’ll do EKGs on them, or Lucy will,” Lotty offered.

She was meeting Max Loewenthal for dinner; she invited Morrell and me to join her, which seemed like a welcome change of pace to both of us. We went to one of the little bistros that have sprung up on the North Side, one that had a wine list Max likes, and lingered late over a bottle of Côte du Rhône. Despite my worries and injuries, it was the most pleasant evening I’d spent since Marcena’s arrival.

In the cab home, I fell asleep against Morrell’s shoulder. When we got to my place, I stood drowsily on the curb, holding his walking stick while he paid off the driver. In the way you don’t really notice things when you’re half asleep, I saw a Bentley across the street, a man in a chauffeur’s uniform at the wheel. I saw the lights in my living room, without thinking about it, but when we’d made our slow way up the stairs, and I saw my apartment door ajar, I woke up in a hurry.

“I’m going inside,” I muttered to Morrell. “If I’m not out in two minutes, call 911.”

He wanted to argue about which of us got to be the hero, or the fool, but he had to agree that between my injuries and his, I was the one in better shape-and I was the one with street-fighting smarts.

Before either of us could do anything, heroic or foolhardy, Peppy and Mitch started barking and whining from the far side of my door. I kicked the door all the way open, then flattened myself against the wall. The two dogs bounded out to greet us. My lips compressed now more with annoyance than fear, I followed them in.

Mr. Contreras was sitting in the easy chair in my living room. Facing him, on the couch, were Buffalo Bill Bysen and his personal assistant, Mildred. Even at ten o’clock on a Saturday night, she wore heavy makeup. Mr. Contreras looked up at me with the same guilt-filled defiance that the dogs use when they’ve been digging up the yard.

“So that’s why there’s a Bentley out there on Belmont: waiting for the head of one of the biggest companies in the world, and he came to visit me.” I rubbed my hands together in a display of fake heartiness. “It’s delightful that you were able to drop in, but I’m afraid I’m going to bed. Help yourself to the liquor cabinet, and keep the music down-the neighbors are picky.”

I went to the front door to tell Morrell that the coast wasn’t exactly clear but it was okay to come in.

“I’m sorry, doll,” Mr. Contreras followed me out. “When they showed up and said they needed to see you, well, you’re always telling me not to butt in, so I didn’t like to tell them ‘no,’ case you’d arranged it; you didn’t want me knowing your plans or nothing today.”

I bared my teeth at him in an evil grin. “How thoughtful of you. How long have they been here?”

“About an hour, maybe a little longer.”

“I have a cell phone, you know, and I’ve given you the number.”

“Do you mind?” Mildred came out to the hall to join us. “Mr. Bysen’s day starts early tomorrow. We need to get this over with so we can return to Barrington.”

“Of course you do. Morrell, this is Mildred-I’m afraid I don’t know her last name-she’s Buffalo Bill Bysen’s factotum. Mildred, this is Morrell. He doesn’t like to use his first name.”

Morrell held out a hand, but Mildred only nodded perfunctorily and turned to lead us back into my apartment.

“Mildred and Buffalo Bill have been sitting in the living room for an hour,” I said to Morrell. “Mr. Contreras let them in, thinking it was an emergency when they showed up uninvited, and now they’re very cross that we didn’t use ESP to drop everything and rush home to look after them.”

“His name to you is Mr. Bysen,” Mildred said through tight lips. “If you treat all your clients this rudely, I’m surprised you have any.”

I looked at her thoughtfully. “Are you a client, Mildred? Or is Buffalo Bill? I don’t remember you hiring me. I don’t remember giving you my home address, either.”

“Mister Bysen,” she said with heavy emphasis, “will explain what he needs you to do.”

When we were all back inside, I introduced Bysen to Morrell, and offered refreshments.

“This isn’t a social visit, young woman,” Bysen said. “I want to know where my grandson is.”

I shook my head. “I don’t know. If that’s all you wanted, you could have saved yourself the drive from Barrington by letting your fingers do the walking.”

Mildred sat herself back on the couch next to Bysen and opened her gold leather portfolio, pen poised, ready to take a note or order an execution at a second’s notice.

“He talked to you on Thursday. You called him, and he talked to you. Now you tell me where he is.”

“Billy called me, not the other way around. I don’t know where he is, and I don’t have his cell phone number. And I promised him I wouldn’t look for him as long as I believed he was safe and not being held against his will.”

“Well, that’s just fine, you talk to the boy on the phone, and you know he’s safe and sound, hnnh? You met him two times, and you know him so well you can tell from his voice on the phone that he’s safe? Do you know how much a kidnapper would like to get hold of one of my grandchildren? Do you know what he’s worth? Hnnh? Hnnh?”

I pressed my right fingers against the bridge of my nose, as if that would push thoughts into my brain. “I don’t know. I’m guessing the company’s worth around four hundred billion, and if you’ve divvied it up evenly-you have six children? So sixty-seven billion a head, and then if young Mr. William is being fair with his own kids, I suppose-”
