Chapter 1 - THREE KNOCKS IN THE NIGHT

Mister, can I borrow your dog for one night? I'm scared to sleep alone.
The words drifted into the study at 10:47, soft as the rain gnawing at the French windows.
Dante Moretti did not lift his head. He thought the wind had made a sentence out of nothing.
Then he heard the breathing. Small and careful, the kind a child uses when she is trying very hard not to be a nuisance.
He looked up.
She stood in the doorway, five years old, brown hair tied crooked on one side as if she had done it herself in the dark. Pajamas printed with planets and blue stars. Two woolen socks that didn't match, one gray, one striped. Against her chest she crushed a pillow shaped like a five-pointed star, its fabric worn thin along one edge.
Dante set down the file he had been reading. On the mahogany desk beside it sat a half-finished espresso. Beside the espresso sat a Beretta, safety on.
He did not move to cover it.
The girl saw it. He watched her see it. She did not flinch. Her eyes slid past him and past the lamplight, to the far corner of the study where Bruno lay by the fireplace, sixty-five kilos of black Cane Corso with his chin on his paws.
She studied the dog with the grave attention of a woman weighing a contract.
How did you get up here? Dante asked.
The back stairs. The ones by the linen room.
Those stairs aren't for children.
Mama's polishing the crystal for the big night. She hugged the pillow tighter. She said I had to sleep by myself. And I can't.
He knew her. Elena's daughter. Elena, the Cuban woman his mother had brought into the house three winters ago, the quietest servant in a house of quiet servants. He had spoken to the child perhaps three times in three years. He knew her name was Sophie. He knew almost nothing else.
Why can't you sleep by yourself?
Sophie's thumb found the loose seam of the star.
Because at night, she said, somebody knocks.
Dante waited.
Three times. On my door. Knock, knock, knock. Her voice dropped to a whisper. And when I open it, nobody's there. Every night. Almost every night.
The fire popped. Dante glanced at Bruno.
In six years, the dog had never shown interest in a stranger. He had watched senators, priests, three ambassadors and a heavyweight boxer walk past him without lifting an ear. Now his broad head was tilted, his amber eyes fixed on this small girl in mismatched socks as though he had been expecting her for a very long time.
Dante almost laughed. Two hours ago he had signed an order that would be felt in Queens by morning. Now a child was negotiating for his dog.
Take him, he said.
Sophie's eyes went wide. She crossed the carpet carefully, as if it were ice, and laid one small hand on Bruno's collar.
The dog rose without a sound.
At the doorway she turned back.
Thank you, Mr. Dante. She paused, as if the next part mattered more. He looks lonely, too.
Then she was gone, and the study was only a room again, with a fire and a file and a gun beside a cold cup.
Dante sat very still. Something in his chest had shifted, small and quiet, and he could not find a name for it.
He listened for the sound of her feet on the back stairs.
Down the corridor, the rain kept knocking at the glass. But that was only rain.
At 11:16, Bruno began barking.
Dante had heard that bark exactly twice in six years.
Once when an armed stranger climbed the south wall.
Once when a fire broke out in the stables.
He was out of his chair before the second bark.
By the time he reached the servants' corridor, the dog was standing outside Sophie's bedroom, teeth bared toward the wall.
Not the door.
The wall.
Sophie stood behind him, clutching her star pillow.
Elena rushed from the linen room, her face white.
"What happened?"
Sophie pointed toward the wallpaper beside her bed.
"The man came back."
Dante looked at the wall.
There was nothing unusual about it.
Then Sophie whispered something that made Elena grab the doorframe.
"He said Mama has to give back the blue book."
Dante turned slowly toward Elena.
"What blue book?"
Elena's lips parted.
No words came.

And Dante understood that the little girl had not come to his study because she was afraid of the dark.
She had come because someone inside his house was hunting her mother.
