St. Agnes stood behind a rusted fence on the edge of a redevelopment zone.
The west wing had burned years ago, but the chapel remained.
Gideon's company had purchased the land after the closure and delayed demolition three times.
Now Evelyn understood why.
Theo brought only two people he trusted. Naomi came despite everyone's objections. Adrian came because Evelyn refused to leave him behind where Gideon could reach him.
Lily came because she was the only person who knew where to go.
"I hate this plan," Naomi said as they cut through the side gate at two in the morning.
"It's not a plan," Adrian replied. "It's a bad decision with flashlights."
"Finally, something we agree on."
Inside, the chapel smelled of mold and old plaster.
Lily walked to the front pew.
"Mom counted seven from here."
Seven tiles from the altar they found a brass fitting embedded in the floor.
It was shaped like a flower.
Two shallow slots sat at its center.
Evelyn stared.
"The clips."
She placed hers into one slot and Mara's into the other.
They fit perfectly.
Nothing happened.
Lily reached down and turned both clips inward at the same time.
A mechanical click sounded beneath the floor.
The altar shifted half an inch.
Adrian pushed it aside.
A staircase descended into darkness.
"How old is this place?" Naomi whispered.
"Older than St. Agnes," Theo said.
The tunnel below had stone walls and modern electrical wiring. Someone had used it recently. Dust covered the edges but not the center path.
They passed three locked doors.
Behind the fourth was a storage room filled with filing cabinets.
Every drawer held patient records.
Thousands of them.
Naomi opened one folder and went pale.
"These aren't just St. Agnes patients. There are cases from facilities in four states."
Adrian opened another.
"Guardianship transfers. Adoption orders. Asset waivers."
Theo found a shelf of red-bound ledgers.
One space was empty.
"The missing book," he said.
A sound traveled through the tunnel.
Metal striking metal.
Lily turned toward the far end.
"Mom?"
Evelyn grabbed her shoulder.
"Stay with me."
They followed the sound to a reinforced door.
A small glass window had been painted black from the other side.
Theo tried the handle.
Locked.
Adrian found an electrical keypad.
"Four digits."
Lily looked at the clips.
"Mom said our birthday opens old doors."
"Whose birthday?"
"Mine."
Evelyn entered Lily's birthday.
Red light.
"Mara's?" Naomi suggested.
Red.
Evelyn tried her own.
Green.
The lock released.
Everyone stared at her.
"Why would my birthday open this door?"
No one answered.
Theo pulled the door open.
The room beyond was empty except for a chair, a portable medical light, and a cassette recorder on the floor.
The recorder was running.
Evelyn pressed stop, rewound a few seconds, and played.
Mara's voice filled the room.
"If you found this, don't follow me. Claire was right. The records under St. Agnes aren't evidence of what Helena did. They're evidence of what someone did using Helena's name."
A pause.
Then another voice spoke in the recording.
Helena.
Evelyn recognized her mother's voice from old home videos.
"Mara, you still don't understand. I died because it was the only way to protect Evelyn."
Mara answered, "From who?"
Helena whispered a name.
The tape warped.
Static swallowed the word.
Then Mara said clearly:
"Evelyn isn't Claire's daughter."
Evelyn felt the room tilt.
The tape continued.
"Claire lied about the adoption. Malcolm lied about the bridge. And you lied about the night Evelyn was born. If she learns what happened in Room Zero, she'll never forgive any of us."
The recording clicked off.
Naomi stared at Evelyn.
"Room Zero?"
Lily tugged at Evelyn's sleeve.
"I know where that is."
Theo shook his head. "There was never a Room Zero on the plans."
Lily pointed to the wall behind the medical chair.
"It's behind there."
A seam ran down the plaster.
Adrian pushed against it.
The wall moved.
Cold air rushed from the darkness beyond.
And somewhere inside, a woman began to cry.
