The school bus had been locked for nearly two hours when a small hand appeared behind the fogged window.

The rain was coming down in sheets when Dana’s cruiser pulled up to the Hale residence in the affluent neighborhood of Oak Ridge.

The house was a beautiful, sprawling two-story brick home with a manicured front lawn and a long stone driveway. A luxury SUV sat parked near the garage.

Dana and Martinez walked up the front steps, their raincoats dripping onto the covered porch. Dana pressed the doorbell.

A moment later, the door was opened by a woman in her late forties. Julianne Hale was tall, elegant, with blonde hair styled in a neat bob, wearing a cream cashmere sweater and pearl earrings. Her face was calm, though her eyes showed the faint, red strain of someone who had spent the afternoon crying.

"Detective Brooks," Julianne said politely, opening the door wider. "Come in out of the rain. Have you found out anything more about... about what happened at the school?"

Dana stepped into the warm, carpeted foyer, holding her badge in her palm. "Mrs. Hale, we need to speak with you regarding your corporate filing for Sovereign Academic Holdings."

Julianne’s hand, which had been resting on the door handle, went rigid. Her polished smile faltered for a fraction of a second before she smoothed her expression back into place.

"I... I’m not sure what you mean," she said, taking a step back into the hallway. "That is a small real estate holding company my family set up for investment properties."

"It’s the company you used to buy off Marcus Vance’s mortgage," Martinez said bluntly, closing the front door behind them. "Marcus Vance, the fleet maintenance director who locked Eli Turner inside Bus 18 this morning."

"That’s insane," Julianne said, her voice rising an octave. "I don't know any Marcus Vance! I don't manage the bus fleet! My husband is the principal, not me!"

"Your husband had an affair nine years ago, Mrs. Hale," Dana said quietly, watching the woman’s facial expressions with hawk-like precision. "He paid two hundred thousand dollars to a woman named Clara Turner to keep a child quiet. A child he believed died five years ago."

Julianne lowered her head. She walked slowly into the formal living room and sat down on the edge of a silk sofa, her posture rigid, her fingers knotting together in her lap.

"I found out three months ago," Julianne whispered, her voice dropping into a flat, icy tone. "I was organizing our joint tax files for our accountant. I found a wire transfer receipt from five years ago. Two hundred thousand dollars sent to a legal trust in Austin."

She looked up at Dana, her eyes filled with an old, poisonous bitterness.

"I spent nine years standing by Andrew," Julianne spat. "I endured his endless work hours, his arrogant school board politics, his pathetic little ego. I gave up my career in corporate law to be the 'perfect principal’s wife.' And all the while, he was funneling our family savings to his bastard child's mother!"

"Did you hire Marcus Vance to kill that boy?" Dana asked directly.

"No!" Julianne snapped, her eyes flashing with anger. "I didn't want the boy dead! I wanted the money back! I found out Clara Turner had faked the child's death to extort Andrew for more money over the years! I bought Vance’s mortgage so he would give me access to the district's internal communications! I was going to expose Clara, ruin Andrew’s reputation, and take every single cent he had in a divorce!"

"Then why was Eli on Bus 18?" Martinez asked.

"I don't know!" Julianne cried out, tears of frustration finally spilling over her lashes. "Clara called me two nights ago! She was terrified! She said someone else was threatening her! Someone who knew about the forged death certificate! She told me she was going to drop the boy at the school so Andrew would be forced to take responsibility publicly!"

Dana stepped closer to Julianne. "Who was threatening Clara, Mrs. Hale?"

"She didn't give me a name," Julianne sobbed, covering her face. "She just said... she said 'he’s coming for the trust money.' That’s all she said!"

Dana’s phone buzzed. It was a text message from the precinct forensic unit analyzing Clara Turner’s house.

Brooks - Medical Examiner preliminary report on Clara Turner: Cause of death was acute insulin toxicity. Manner of death: Homicide. Fingerprints found on the syringe match a prior record: Deputy Superintendent Robert Sterling.

Dana looked at Martinez.
