Chapter 1 - The Threshold of Silence

The first thing Mara Bell heard was the bed striking the wall.
The second was her daughter’s heel kicking against the floor.
Mara dropped the laundry basket and ran toward twelve-year-old Maisie’s bedroom. The door was almost closed. Through the narrow opening, she saw her seventeen-year-old son kneeling over his sister.
Callum had Maisie pinned against the mattress.
One hand was beneath her jaw. The other appeared to be pressed against the side of her neck.
Maisie’s face had turned dark red. Her mouth opened and closed without making a sound. Her fingers clawed at Callum’s wrists while her legs thrashed beneath the blanket.
“Callum!”
He looked up.
His face was white with terror.
“Mom, call an ambulance.”
Mara rushed into the room and grabbed his shoulder. “Get off her!”
“Don’t move her!”
“You’re hurting her!”
“She can’t breathe!”
Mara pulled him backward with all her strength. Callum fell against the nightstand, knocking over a lamp.
The moment his hand left Maisie’s jaw, her head rolled sideways. Her struggling stopped.
“Maisie?”
Mara gathered her daughter into her arms.
The girl was limp.
“No. No, baby, wake up.”
Callum scrambled back onto the bed. “Lay her flat.”
“Stay away from her!”
“There’s something in her throat.”
Mara stared at him. Red marks were already forming along Maisie’s jaw and neck.
“What did you do?”
“I didn’t do anything. She came into my room choking.”
“You were holding her down.”
“I was keeping her airway open.”
Mara reached for her phone, but before she could unlock it, blue lights swept across the bedroom walls.
A siren stopped outside the house.
Callum turned toward the window.
“Did you call them?” Mara asked.
“No.”
Two police officers entered the house moments before the paramedics. They found Mara kneeling beside the bed and Callum standing near the wall with scratches across both arms.
One officer moved between him and Maisie.
“Hands where I can see them.”
Callum raised his hands. “She needs help first.”
The paramedics placed Maisie on the floor. One tried to ventilate her while the other examined her mouth.
“Severe obstruction,” the medic said. “Minimal air movement.”
Callum pointed toward Maisie’s chin. “Keep her jaw forward. When I held it there, she got a little air.”
The officer seized his wrist.
“Turn around.”
“What?”
“Turn around and place your hands behind your back.”
Mara watched the metal cuffs close around her son’s wrists.
For one terrible second, Callum looked younger than seventeen.
“Mom,” he said. “Tell them I was helping her.”
But Mara could still see his hands around Maisie’s neck.
“I saw you holding her down.”
The words left her mouth before she understood what they would do.
Callum stopped struggling.
The paramedics rushed Maisie downstairs. As the officer guided Callum toward the hallway, he stared at the torn white rabbit lying beside the bed.
The stuffed animal had been a gift from Vincent, Mara’s ex-husband.
A split seam ran across its stomach. Small pieces of stuffing covered the floor.
Callum suddenly pulled against the officer.
“Check the rabbit.”
“Keep moving.”
“There was something inside it.”
The officer tightened his grip.
Callum looked directly at his mother.
“Someone was listening to us.”
At the hospital, Dr. Sloane Harper ordered an emergency scan after the breathing tube failed to pass normally.
The image appeared on the monitor several minutes later.
A small metallic object was lodged above Maisie’s vocal cords.
Dr. Harper leaned closer.
“That isn’t food.”
Mara wrapped both arms around herself. “What is it?”
“I won’t know until we remove it.”
A technician enlarged the image.
Inside the narrow capsule was a battery, a circuit board and what appeared to be a tiny antenna.
Dr. Harper’s expression changed.
“Mara, this looks like a listening device.”
Before Mara could answer, the technician pointed toward a faint mark on the screen.

The device still had power.
And somewhere outside the operating room, it was still transmitting.
