The first thing Roman Calder heard was the lock sliding into place behind him. Not the click of an ordinary door. A bolt. Heavy steel dragging across steel. Roman turned. Through the narrow pane of reinforced glass, a black coat disappeared around the end of the corridor.

For half a second, he simply stared. Then came the hiss. Soft. Steady. Almost polite. Roman looked toward the vent above the pantry shelves. A gray vapor curled through the metal grille.

“Son of a—”

He lunged for the door. The handle turned, but the door opened less than an inch before striking the outside bolt. Roman slammed his shoulder against it. Nothing. He tried again.

The room had once been built as a wine-storage chamber before renovations converted it into a secure pantry. Thick walls. Reinforced door. No window except the narrow glass panel facing the service hallway. A room designed to keep things in. Tonight, someone had remembered that.

Roman pulled his phone from his pocket. No signal. That was wrong too. There were signal repeaters throughout the Calder estate. He had paid enough for them to make a call from the bottom of the swimming pool if he wanted. Someone had disabled the east wing.

The hiss grew louder. Roman looked up. The smell reached him next—sharp, bitter, industrial. His stomach tightened. He knew enough to understand that whoever had locked him inside had not intended to frighten him. They intended to wait until he stopped breathing.

Roman lifted the brass serving cart beside the wall and smashed it against the glass. Once. Twice. The glass shuddered but held. He raised the cart again.

Then something moved beyond the door. Small. Roman froze.

A little boy stepped into view. Four years old. Brown hair falling over one eyebrow. Red sweater. One shoelace undone. Owen Dawson. The housekeeper’s son.

Roman dropped the cart. “Owen.”

The boy brightened when he recognized him. “Mister Roman?”

Roman walked toward the glass and immediately felt the room tilt. Too fast. Already too much gas. “Don’t come closer.”

Owen stopped. His smile disappeared. “Why?”

“Go find your mother.”

“But your door—”

“Owen.” Roman put every ounce of authority he had left into the child’s name. Men twice Owen’s size had obeyed that voice without hesitation.

The child did not. He stared through the glass. Roman saw the moment Owen understood something was wrong. Children did not understand poison or betrayal or succession wars. But they understood when an adult could no longer stand properly.

Roman gripped the doorframe. “Go.”

Owen looked behind him. No one. Then his eyes shifted upward. There was a red alarm box on the wall beside a wooden bench. Roman followed the boy’s gaze.

“No.”

Owen dragged the bench toward the wall.

“Owen, listen to me.”

The boy climbed.

“Get down.”

Owen reached. His fingers missed the alarm lever. He stretched farther. The bench rocked beneath him. Roman’s heart slammed harder than the poisoning could explain.

“Owen!”

The boy caught the handle with both hands and pulled.

The mansion began to scream. Sirens exploded through the corridor. Red lights spun above the service doors. Fire doors released. Somewhere deeper in the house, bells hammered through three floors of stone, oak, and stained glass.

Owen nearly fell from the bench. He caught himself. Then shouted the most reassuring word Roman had heard all night.

“Mommy!”

Footsteps thundered from the laundry room. Clare Dawson appeared around the corner carrying folded towels. She dropped them.

“Owen!”

The boy pointed. “Mr. Roman can’t get out.”

Clare ran to him. She was thirty-two, broad-shouldered, fair-skinned, with auburn hair twisted into the practical knot she wore during work. Six years in Roman Calder’s mansion had taught her the location of every fuse box, linen cabinet, water valve, emergency exit, medicine kit, and temperamental window latch. It had also taught her not to panic merely because powerful men were panicking around her.

But when she saw Roman behind the glass, her face changed. He had one hand pressed to the wall. The other hung uselessly at his side.

“Back away from the door,” she ordered.

Roman almost laughed. Even dying, he appreciated the irony. “Take Owen outside.”

“I said back away.”

“Clare.”

“Roman.”

It was the first time she had used his name without Mister. The first time she had sounded as if she might drag him out of hell simply to argue with him afterward.

She lifted Owen off the bench. “Corner. Low to the floor. Sleeve over your mouth.”

“Mom—”

“Now.”

Owen obeyed. Clare pulled the master key from her waist and pushed it into the door. It entered. It would not turn. Then saw why. The outside bolt. Mounted high. Closed. Her eyes narrowed. Someone had locked him inside from the hallway.

Clare shoved the bolt open and twisted the key. The door moved an inch. Roman’s body blocked it.

“Move away.”

“I’m trying.” His voice barely carried.

That frightened her more than shouting would have. Roman Calder did not run out of voice.

Clare wedged both hands through the opening. “Give me your wrist.”

“Get the boy out first.”

“If you want to protect him, help me open this door.”

Something about that reached him. Roman pushed. Clare pulled. The opening widened. Poisoned air rolled into the corridor. Clare covered her nose with her apron, caught Roman under one arm, and pulled.

He was nearly a foot taller than she was. She could not lift him. So she used the slick marble floor, the linen runner beneath them, and whatever strength remained in his legs.

“One step.”

Roman gave her one.

“Again.”

Another. His knees buckled. Clare grunted as his weight crashed into her shoulder.

“Don’t you dare make me carry you.”

“Bossy woman.”

“You can fire me tomorrow.”

“Tempting.”

That faint attempt at humor told her he was still conscious. Together they crossed the threshold. Fresh air rushed through the fire doors. Clare dragged him toward the open courtyard entrance. Emergency workers appeared from the south hall wearing respirators. One took Roman. Another ran toward the gas source.

Owen broke from his corner. “Mommy!”
