The rain came the way it only came in October: thin, cold, and without end.

Rosa held her daughter's hand so tightly her knuckles ached, and still she could feel the small fingers working themselves loose. The driveway of the Cain Estate stretched ahead of them, pale gravel gone dark with water, and at the end of it the house sat against the sky like something that had been there longer than Massachusetts had.

"Stay close," she whispered.

"I am close."

"Closer."

Six years old and afraid of nothing. That was the problem.

Rosa had worked in that house for two years and in all that time she had never once brought Sophia through the gate. The school had called at noon — a pipe had burst, the building was closed, come get your child — and there was no one. No sister. No neighbor. No money for a sitter. So she had done the only thing left to her and brought her daughter to the one address in the city where children did not belong.

Everyone on staff understood one thing without being told. You did not draw attention to yourself around Mr. Cain.

He was polite. He paid above market. He never raised his voice. But black cars arrived at strange hours, and men in dark suits stood by the gate for entire afternoons without speaking, and once Rosa had watched him take a call in the study and hang up with a hand that trembled so slightly she would have missed it if she had not been dusting the shelf two feet away.

Nobody explained who he was. Nobody had to.

"Through the courtyard," Rosa said. "Servants' entrance. Don't wander. Don't touch anything. Don't speak unless spoken to."

Sophia nodded the way children nod when they have already stopped listening.

They were halfway across when the growl rolled out of the dark.

Rosa froze. Chained near the old carriage house, half swallowed by the shadow of the wall, was Zeus.

He was enormous — a Cane Corso, black as wet slate, shoulders like a bull's, a pale scar cutting across one eye. The guards fed him. The guards walked him. Nobody else went near. Not because Mr. Cain forbade it, but because the one time a new gardener had tried, Zeus had put him flat on the ground in under two seconds and stood over him without biting, just staring, until somebody called him off.

After that the staff had settled into an unspoken rule. You did not go near the dog.

Rosa reached for her daughter's shoulder. Her hand closed on air.

"Sophia—"

She was already walking.

Rosa would relive those ten seconds for the rest of her life. The rain falling silver under the courtyard lamps. Her own voice breaking as she said her daughter's name. And Sophia, small and fearless, crouching in front of a hundred and twenty pounds of trained muscle, looking him straight in his one good eye.

"Hi," she said. "You look lonely."

The growling stopped. Rosa did not breathe.

Somewhere behind her, a door opened. Footsteps crossed wet stone.

"Sophia," Rosa whispered. "Please, baby. Don't move."

Zeus took one slow step forward. Then another. Then he lowered his enormous head and pressed it into the child's small hands as if he had been waiting his entire life for somebody to ask him how he was.

The front door closed softly behind her.

When Rosa turned, Damon Cain was standing on the top step in the rain, not moving, staring at the two of them with an expression she had never seen on his face before.

"Mr. Cain." Her voice came out cracked. "I'm so sorry. She got away from me. She's never—"

He raised one hand. Not sharply. Just enough. He came down the steps slowly, his shoes clicking against the wet stone, and for the first time since she had started working there, he looked genuinely uncertain.

"How long has she been talking to him?"

"Seconds. Only seconds, sir. I swear."

He crouched a few feet away — careful, the way you approach something fragile rather than something dangerous. Zeus's ears flicked toward him. The dog did not move away from Sophia.

"He's never done that," Cain said quietly, almost to himself. "Not with anyone."

Sophia looked up at him without a trace of fear, the way only a child can look at a man grown adults trembled around. "He's a good dog," she said. "He was just waiting for somebody to be nice to him."

Rosa expected many things. Anger. A sharp order to leave. A cold reminder that she had broken the rules by bringing her daughter into that house at all.

What she did not expect was for Damon Cain to lower himself all the way down onto the wet stone in his expensive suit and simply sit there.

"What's your name?" he asked.

"Sophia."

Something crossed his face. Quick. Painful. Gone before she could be certain she had seen it.
