THE NIGHT THE SHED OPENED

Kristin kept the pharmacy cap in the zippered pocket of her handbag.

The next day, she drove to Georgia's condominium.

She told Ethan she had a client meeting. The lie sat badly with her, but she could not ask him to help until she knew whether his mother had lied about the flood. If the condominium was truly uninhabitable, Kristin would apologize. She would blame hormones, exhaustion, anything necessary to repair the damage.

The building manager recognized Georgia's name.

"Unit 204?" he said. "No flood there. We had a pipe break in 307 last winter, but 204 is fine."

"Are you sure?"

He checked his tablet. "Mrs. Cole requested a temporary water shutoff before she left. Said she'd be away with family."

Kristin sat in her car for several minutes afterward, both hands on the steering wheel.

The relief she had expected from proof did not come. Proof only gave the fear a shape.

Georgia had invented an emergency to enter their home.

When Kristin returned, she found the back door open. Georgia was in the yard carrying a cardboard box toward the shed.

"Need help?" Kristin called.

Georgia stopped. "No."

"What's in the box?"

"Old things Ethan asked me to sort."

"He told me the shed was empty."

"Then perhaps he doesn't tell you everything."

Georgia unlocked the brass padlock and stepped inside. Before the door closed, Kristin glimpsed shelves that had not been there when they bought the house. Bottles lined the upper one. File boxes filled the lower.

She waited until Georgia went grocery shopping.

The brass padlock was too strong to cut with the small tools in the garage, but the rear wall of the shed had a loose board. Kristin worked it free with a screwdriver, careful not to split the wood. The gap was barely wide enough for her arm.

She reached inside and took several photographs with her phone.

The first showed the edge of a folding cot.

The second showed a shelf of canned food, bottled water, and medical supplies.

The third caught the lower part of the interior door. A name had been carved into the wood again and again.

RACHEL.

Kristin dropped the phone.

It landed in the grass without breaking. She picked it up, replaced the board, and returned to the kitchen just as Georgia's car entered the driveway.

Ethan came home after seven. Kristin waited until Georgia was in the shower before showing him the photographs.

He went still at the third image.

"Who is Rachel?" Kristin asked.

"My sister."

She had known Ethan for five years. They had been married for two. He had never mentioned a sister.

"Where is she?"

"I don't know."

He sat on the edge of the bed and stared at the phone. The construction site, dinner, his wet jacket on the chair all seemed to disappear from his awareness.

"She was ten years older than me," he said. "She left when she was eighteen. Mom said Rachel stole money and ran off with a man."

"How old were you?"

"Eight."

"Did you see her leave?"

"No. I woke up, and she was gone."

Kristin sat beside him. "Why is her name inside our shed?"

"It can't be the same shed."

"What do you mean?"

Ethan enlarged the picture. His face had lost its color.

"We lived in this neighborhood when I was a kid," he said. "Three streets over, I think. After Dad died, Mom sold the house and we moved across town."

"Did this shed belong to your family?"

"I don't know. I hardly remember the old place."

"Ethan, Georgia lied about the flood."

He looked at her.

Kristin told him what the building manager had said. She expected disbelief, perhaps anger that she had investigated his mother. Instead, he stood and went to the guest room.

Georgia emerged from the bathroom in a robe, drying her hair.

"Why did you lie about your condo?" Ethan asked.

The towel stopped moving.

"Who says I lied?"

"The building manager."

Georgia looked past him at Kristin. "You went to my home?"

"Answer him," Kristin said.

Georgia tightened the robe belt. "I was lonely. Is that the crime? I retired, and suddenly there was no one. You two are having a baby. I wanted to feel included. If I had simply asked to stay, Kristin would have said no."

"You don't know that," Ethan said.

"Don't I?"

He showed her the photograph of Rachel's name.

Georgia's knees appeared to buckle. She caught the bedpost.

"Where did you get that?"

"The shed."

"You broke in?"

"Why is Rachel's name there?"

Georgia's gaze went from the phone to Kristin. Hatred surfaced for less than a second, but it was unmistakable.

"Your sister was troubled," she said. "After she disappeared, I stored her belongings in that shed. Seeing them was painful, so I locked the door."

"How did her belongings get into a shed behind a house we bought last year?"

Georgia sat slowly on the bed. "Because this was our house."

Ethan laughed once, without humor. "No."

"Your father used a different last name on the deed. After he died, the bank took the property. It changed hands twice. You were too young to remember the address. When you and Kristin showed me the listing, I recognized the kitchen window. I thought you knew."

Kristin felt the room tilt around her.

They had not found the house by chance. Georgia had forwarded the listing to Ethan, calling it an affordable opportunity in a good neighborhood.

"You brought us here," Kristin said.

"I helped my son buy a home."

"You brought us back to the place where his sister vanished."

Georgia's eyes filled with tears. "Rachel ran away. I have lived with that shame for twenty-seven years. Do you think I wanted to tear open the wound?"

"Open the shed," Ethan said.

"Tomorrow."

"Now."

"It's dark, and the floor is unsafe."

"Give me the key."

Georgia reached into the robe pocket, then froze.
