THE MAFIA BOSS THOUGHT LILY HAD SAID SOMETHING SILLY, UNTIL THE GLAMOROUS WOMAN SHE POINTED AT SUDDENLY LOOKED NERVOUS

The first thing I noticed was that Lily had stopped asking for cake.

For my daughter, that was almost as alarming as a fire alarm.

Three-year-olds have priorities. Hers included strawberry frosting, pink shoes, and the absolute conviction that clouds were sheep who had gotten lost. We had been standing beside the dessert table at the DeLuca Foundation's winter gala for twelve minutes, and Lily had asked about the miniature cakes exactly eleven times.

Then she pointed across the ballroom.

"Mama," she said, "that lady's belly fell off upstairs."

I followed her finger.

Alessia Vieri stood beneath a crystal chandelier in an emerald evening gown, one hand resting on a perfectly rounded stomach. A photographer leaned toward her. Three women smiled. Beside them stood Marcello DeLuca, the thirty-eight-year-old businessman who owned the hotel, the development company sponsoring the gala, and approximately half the rumors people told about Chicago after midnight.

I gently lowered Lily's arm.

"Sweetheart, don't point."

"But it fell."

"Sometimes dresses look different from different angles."

Lily looked at me as though I'd suggested fish could ride bicycles.

"No, Mama. It went plop."

I should explain how we'd ended up there.

My name is Grace Walker. I'm twenty-nine. I arrange flowers for a living, keep spreadsheets because flowers don't pay invoices by themselves, and have raised Lily alone since her father died two years earlier. My biggest client was a wedding coordinator who hired me to decorate hotel events when her regular suppliers were unavailable.

That afternoon, the hotel daycare provider had canceled at the last minute. The foundation was hosting a family-friendly reception before the formal gala, so my supervisor agreed to let Lily remain with me for the first hour. My sister Jo was due to pick her up at nine.

Nothing in the job description said I would become the person whose child accused a billionaire's future bride of wearing a removable stomach.

Across the room, Alessia's smile tightened.

She had heard.

"What a funny little imagination," she said brightly, walking toward us. Her perfume reached us first, sweet and expensive. "Children say the strangest things."

"I'm sorry," I answered. "She's overtired."

Lily frowned. "I'm not tired. Your belly was on the floor."

The photographer stopped taking pictures.

Alessia crouched, carefully, as if her dress were too delicate to bend.

"You must have seen a pillow, darling."

"It had straps," Lily replied.

A small silence opened between us.

Marcello turned.

He was not smiling. His eyes moved from Alessia to Lily and then to me. I knew his reputation: difficult with employees, ruthless in negotiations, impossible to intimidate. I also knew he had funded a neighborhood center called Harbor House, where Lily and I attended a free Saturday music program. People were rarely only one thing.

"What's your name?" he asked Lily.

"Lily. Like the flower."

"I know the flower." He crouched until they were eye level. "What did you see?"

"The green lady took off her big belly in the upstairs room. Then she put it away."

"Lily," I whispered.

Alessia laughed sharply. "Marcello, please. Are we seriously questioning a toddler in the middle of our evening?"

He didn't look away from my daughter.

"Can you show me where?"

Lily nodded with the solemn pride of someone finally being understood.

"Where she hid it."

I put a hand on Lily's shoulder. "Mr. DeLuca, she wandered ahead of me earlier while I was checking the flowers on the mezzanine. I'm sorry. I should have kept her closer."

"Was she alone?"

"For less than a minute. I found her outside the guest powder room."

That wasn't quite the full truth. Lily had been looking for a bathroom while a delivery elevator blocked the corridor. But she was safe now, and I was not about to march her into a stranger's private suite on the basis of a child's observation.

"We can discuss it with security," I said. "Without her going anywhere."

Marcello studied me for a moment, then nodded.

"Agreed."

Alessia touched his sleeve. "This is absurd. You'll humiliate me in front of our donors over something a little girl imagined?"

"No," he said. "I'm going to find out whether she was somewhere she shouldn't have been. That's all."

He motioned to a woman with a headset. "Get the floor manager. And please find a quiet room for Ms. Walker and her daughter."

"You know her name?" Alessia asked.

"It's on her staff badge."

It was such a simple answer that I almost smiled.

Instead, I followed the floor manager into a small sitting room behind the ballroom. I could hear a string quartet through the wall. Lily immediately asked whether the cake would still be there when we returned.

"Probably," I told her.

"Good. I want the pink one."

A woman named Mrs. Rios arrived with water and a plate of crackers. She said she was the hotel's guest-services director, and she spoke to Lily as though Lily were a guest rather than a problem. It helped me breathe.

Ten minutes later, Marcello entered with a female hotel security supervisor, not the two men who followed him around at public events.

"Grace, this is Anita Flores," he said. "She'll take your account if you're willing. Lily doesn't need to repeat anything she doesn't want to."

I appreciated that more than he could know.

Lily was drawing circles on a notepad. Anita sat at the other end of the table and asked only whether Lily had gotten lost upstairs.

"I went where the bathroom sign points," Lily said. "The green lady was talking loudly. Then the belly made a plop."

"Did the lady see you?"

"After. She told me go back downstairs."

"What happened next?"

Lily drew a rectangle and a smaller rectangle inside it.

"She took the belly behind the shiny wall. The wall opened."

Anita and Marcello exchanged a glance.

"A cabinet?" I asked.

"No, Mama. The mirror door. Like at Aunt Jo's house where the coats live."

A mirrored wardrobe.

"Which room?" Anita asked.

"With the swans."

I blinked. There were swans embroidered on the draperies of the north mezzanine suite. I'd delivered an arrangement there that morning.

"The Marigold Suite," I said. "Two silver swans on the window curtains."

Anita checked her tablet. "That suite is registered to Ms. Vieri."

"Of course it is," Marcello said quietly.

Alessia had told the press she was five months pregnant with his child. The engagement was rumored to be announced tonight. I'd seen her photograph in magazines, read comments celebrating their love, and thought nothing more about it. I had no reason to.

Now I was staring at my daughter's drawing of a secret compartment.

"You don't have to involve us any further," I said.

"I won't," Marcello answered. "But if someone frightened your daughter, I need to know."

That was when his phone vibrated.

He read the screen, and something closed in his expression.

"Anita. Nobody goes into that suite without you. Secure the corridor first."

"What's wrong?" I asked.

"Our security chief says the cameras on that hallway are unavailable. They went offline at eight seventeen."

I looked at the clock. It was eight fifty-four.

"Lily and I were up there around eight twenty."

"I know."

He had not accused me of anything. Yet my throat went dry. Missing footage is a useful thing to have when you want someone else's story to disappear.

A knock came at the door.

A hotel employee presented Marcello with a cream envelope. He opened it, read one page, then read it again.

"Who sent that?" Anita asked.

"My attorney's office, supposedly. A notification of a document waiting for my electronic approval."

"What document?"

"A family protection agreement." His voice was flat. "It would put my Harbor House property shares under joint management when Alessia and I marry."

I knew Harbor House. I knew its battered piano, its free meals, the volunteers who remembered children's birthdays. The entire east side of our neighborhood would have been poorer without it.

"Isn't that a normal prenup thing?" I asked cautiously.

"Not the way this one is written. And my attorney says his office didn't send it."

He took out his phone and called someone. I heard only fragments.

"Freeze the approval portal ... all sessions ... independent counsel, not Victor ... Yes, tonight."

When he ended the call, he stood very still.

"Victor?" I repeated.

"Victor Kane. My head of security."

A memory brushed against me. Upstairs, outside the Marigold Suite, I'd seen a tall man in a security jacket moving a laundry cart away from the corridor. He'd watched me find Lily. At the time, he had looked irritated by a child standing in his way.

"I saw him on the mezzanine," I said.

"When?"

"Just before I found Lily. Around eight twenty."

Marcello looked at Anita.

"Then we don't use his camera report."

He turned back to me. "I want to be clear. You've done nothing wrong. You and Lily can leave when your sister arrives. Your contract will be paid in full."

Lily tapped his sleeve.

"Mister?"

"Yes?"

"There's a blue star on the belly."

For the first time, Marcello looked surprised rather than concerned.

"A blue star?"

"Inside. On a little pocket. Green lady put a tiny square in it. Then she hid the whole thing."

He lowered his gaze to the cream envelope.

A blue star was stamped beside the electronic approval number.

"That's odd," he murmured.

Anita's tablet pinged. She read a message, her face tightening.

"The Marigold Suite is empty. The mirror cabinet's been cleaned out. And the security logs show someone used a master card six minutes ago."

"Whose card?" Marcello asked.

Anita hesitated.

"Yours."

I watched him absorb that.

Someone had used the boss's access to remove whatever my daughter had seen. Someone had shut off a camera, prepared a document he hadn't authorized, and placed a blue star where Lily remembered one.

Then the ballroom announcer came through the wall, his voice rising above the music.

"Ladies and gentlemen, please welcome Miss Alessia Vieri. She has a very special announcement to make with Mr. DeLuca this evening."

Marcello didn't move.

Instead, he looked at Lily's drawing and said, "Grace, if Lily saw a place to hide something, perhaps the person who moved it assumed nobody else did."

Lily carefully colored a tiny star beside the rectangle.

"She said the other man would come back for it," my daughter said.

The room went colder.

"What other man?" I asked.

Lily looked up at me.
