### Part 1

The elevator ride to the thirty-second floor usually calmed me. As the numbers climbed, Miami Beach dropped away beneath me, along with the traffic, the horns, and the constant humid buzz of the city. My condo had always been the opposite of the house where I grew up: pale stone, clean lines, quiet rooms, nothing piled on anything else. I had designed every inch of it myself, and I was proud of the fact that walking through the front door felt like lowering the volume on the entire world.

That afternoon, however, I wasn’t alone. Beside me stood Ethan Cole, the property manager handling the rental while I prepared to move my design firm to California. Behind us were Peter and Lauren Walsh, a physician and his wife who wanted the condo for two years while Peter worked at a nearby hospital. They were ideal tenants—quiet, financially secure, no pets, no interest in parties—and they had already discussed paying several months in advance. The rent would cover most of the early expenses for my new showroom in Los Angeles.

“The afternoon light is the best part,” I told them as the elevator slowed. “And the building is incredibly quiet.”

The doors opened.

Lauren stopped before taking a single step.

“What is that smell?”

It hit me an instant later: stale cooking oil, old laundry, artificial fruit punch, and something sour underneath all of it. My stomach tightened. Ethan frowned and checked his tablet. “The cleaning crew confirmed the unit was ready yesterday.”

I crossed the hallway quickly and pressed my thumb to the electronic lock.

Red light.

Access denied.

I tried again.

Red.

My pulse jumped. I pulled the emergency key card from my wallet, slid it through the reader, and heard the lock release.

The front door opened three inches.

Noise poured through the gap—cartoon voices, children shouting, something crashing in the kitchen.

I pushed the door wider.

For several seconds, I honestly wondered whether I had stepped onto the wrong floor.

My cream-colored sofa was buried under clothes, blankets, snack bags, and pizza boxes. Toys covered the marble floor. One of my dining chairs had been dragged in front of the television. There were fingerprints across the glass coffee table, purple juice stains on the rug, and marker drawings on a wall I had paid a painter to finish by hand.

Then I saw my sister.

Melissa was lying sideways across the sofa wearing gray sweatpants and an oversized T-shirt, eating chips directly from a family-sized bag. Her fifteen-year-old daughter, Chloe, sat in my reading chair with dirty sneakers pressed against the leather. Her two younger sons were racing remote-controlled cars around a sculpture pedestal.

Melissa glanced toward the doorway.

Her expression wasn’t embarrassed.

It wasn’t frightened.

She looked irritated.

“Claire?” she said. “Why didn’t you call first?”

I stared at her. “Why would I call before entering my own home?”

Behind me, Lauren whispered, “Oh my God.”

.

Melissa finally noticed the strangers. “Who are they?”

“The people who were going to rent this condo.”

Peter looked around once more. “Were going to.”

“Please,” I said, turning toward him. “Give me twenty-four hours. Something has obviously happened.”

Lauren shook her head. “I’m sorry. This isn’t what we were shown.”

The elevator doors closed behind them less than a minute later. Ethan followed, promising to call me after he tried to salvage the deal.

Then I was alone with Melissa.

I stepped carefully over a plastic dinosaur. “Explain.”

She ate another chip. “We needed somewhere to stay.”

“How did you get inside?”

“Mom helped.”

My skin went cold.

Melissa stood and walked into the kitchen, where sticky jelly covered one side of my quartz island. She opened my refrigerator, took out a bottle of water, and twisted the cap.

“Mom said you were moving anyway. She said leaving a place this big empty while I was struggling was ridiculous.”

“It wasn’t going to be empty. You just watched my tenants leave.”

.

Melissa rolled her eyes. “Those people looked unbearable.”

“They were going to pay fifty-eight hundred dollars a month.”

“Of course that’s the first thing you mention. Money.”

I laughed because the alternative was screaming. “This property is part of my business plan. The rental income is financing my California expansion.”

“You have plenty of money.”

“And you don’t get to decide what happens to it.”

Her face hardened.

I demanded the key. After several seconds, she reached into her pocket and dropped a silver emergency fob onto the countertop.

I recognized it immediately.

It belonged in a small zippered compartment inside my purse.

“Where did you get that?”

“Mom.”

“She couldn’t have had it.”

Melissa gave me a smug little smile. “Remember when you came over two weeks ago and used the bathroom?”
