It was a loud, aggressive bark, the kind she gave when a stranger was at the door. Someone was coming. Kit pushed through the swing door that led to the dining room. The dog was standing with her forepaws on the windowsill.

Kit went to the window. The snow had eased to a light scatter of flakes. He looked toward the woods and saw, emerging from the trees, a big truck with a flashing orange light on top and a snowplow blade in front.

"They're here!" he called out.

Nigel came in. The dog growled, and Kit said, "Shut up." Nellie retreated to a corner. Nigel flattened himself against the wall beside the window and peered out.

The snowplow cleared a path eight or ten feet wide. It passed the front door and came as close as it could to the parked cars. At the last moment it turned, sweeping away the snow in front of Hugo's Mercedes and Miranda's Previa. Then it reversed to the garage block, turned off the drive, and cleared a swath of the concrete apron in front of the garage doors. As it did so, a light-colored Jaguar S-type came past it, using the track it had made in the snow, and pulled up at the front door.

A figure got out of the car: a tall, slim woman with bobbed hair, wearing a leather flying jacket with a sheepskin lining. In the reflected light from the headlamps, Kit recognized Toni Gallo.

"Get rid of her," said Nigel.

"What's happened to Daisy? She's taking a long time-"

"She'll deal with your sister."

"She'd better."

"I trust Daisy more than I trust you. Now go to the door." Nigel retreated into the boot lobby with Elton.

Kit went to the front door and opened it.

Toni was helping someone out of the back of the car. Kit frowned. It was an old lady in a long wool coat and a fur hat. He said aloud, "What the hell…?"

Toni took the old lady's arm and they turned around. Toni's face darkened with disappointment when she saw who had come to the door. "Hello, Kit," she said. She walked the old woman toward the house.

Kit said, "What do you want?"

"I've come to see your father. There's an emergency at the laboratory."

"Daddy's asleep."

"He'll want to wake up for this, trust me."

"Who's the old woman?"

"This lady is my mother, Mrs. Kathleen Gallo."

"And I'm not an old woman," said the old woman. "I'm seventy-one, and as fit as a butcher's dog, so mind your manners."

"All right, Mother, he didn't mean to be rude."

Kit ignored that. "What's she doing here?"

"I'll explain to your father."

The snowplow had turned around in front of the garage, and now it returned along the track it had cleared, heading back through the woods toward the main road. The Jaguar followed.

Kit felt panicked. What should he do? The cars were leaving, but Toni was still here.

The Jaguar stopped suddenly. Kit hoped the driver had not seen something suspicious. The car reversed back to the house. The driver's door opened, and a small bundle fell out into the snow. It looked, Kit thought, almost like a puppy.

The door slammed, and the car pulled away.

Toni went back and picked up the bundle. It was a puppy, a black-and-white English sheepdog about eight weeks old.

Kit was bewildered, but he decided not to ask questions. "You can't come in," he said to Toni.

"Don't be stupid," she replied. "This is not your house, it's your father's, and he'll want to see me." She continued walking slowly toward him with her mother on one arm and the puppy cradled in the other.

Kit was stymied. He had expected Toni to be in her own car, and his plan had been to tell her she should come back later. For a moment, he considered running after the Jaguar and telling the driver to come back. But the driver would surely ask why. And the police in the snowplow might ask what the fuss was about. It was too dangerous. Kit did nothing.

Toni stood in front of Kit, who was blocking the doorway. "Is something wrong?" she said.

He was stuck, he realized. If he persisted in trying to obey Nigel's orders, he might bring the police back. Toni on her own was more manageable. "You'd better come in," he said.

"Thanks. By the way, the puppy's name is Osborne." Toni and her mother stepped into the hall. "Do you need the bathroom, Mother?" Toni asked. "It's just here."

Kit watched the lights of the snowplow and the Jaguar disappear into the woods. He relaxed slightly. He was saddled with Toni, but he had got rid of the police. He closed the front door.

There was a loud bang from upstairs, like a hammer hitting a wall.

"What the heck was that?" said Toni.

MIRANDA had taken a thick sheaf of pages from the book and folded them into a wedge which she had shoved into the gap under the cupboard door. That would not hold Daisy for long. She needed a more solid barrier. Beside the bed was an antique commode chest used as a bedside table. With a huge effort, she dragged the heavy mahogany chest across the carpet, tilted it at a forty-five-degree angle, and jammed it against the door. Almost immediately, she heard Daisy pushing at the other side of the door. When pushing failed, she banged.

Miranda guessed Daisy was lying with her head in the attic and her feet in the cupboard, kicking the door with the soles of her boots. The door shuddered but did not fly open. However, Daisy was tough, and she would find a way. Nevertheless, Miranda had won a few precious seconds.

She flew to the window. To her dismay, she saw two vehicles-a truck and a sedan-driving away from the house. "Oh, no!" she said aloud. The vehicles were already too far for the people inside them to hear her scream. Was she too late? She ran out of the bedroom.

She stopped at the top of the stairs. Down in the hall, there was an old woman she had never seen before, going into the bathroom.

What was happening?

Next she recognized Toni Gallo, taking off a flying jacket and hanging it on the hat stand.

A small black-and-white puppy was sniffing the umbrellas.

Kit came into view. There was another bang from the dressing room, and Kit said to Toni, "The children must be awake."

Miranda was bewildered. How could this be? Kit was acting as if there was nothing wrong…

He must be fooling Toni, Miranda realized. He was hoping to make her think that all was well. Then he would either persuade her to leave, or overpower her and tie her up with the others.

Meanwhile, the police were driving away.

Toni closed the bathroom door on her mother. No one had yet noticed Miranda.

Kit said to Toni, "You'd better come into the kitchen."

That was where they would jump her, Miranda guessed. Nigel and Elton would be waiting, and they would take her by surprise.

There was a crash from within the bedroom: Daisy had broken out of the cupboard.

Miranda acted without thinking. "Toni!" she screamed.

Toni looked up the stairs and saw her.

Kit said, "Shit, no-"

Miranda yelled, "The thieves, they're here, they've tied Daddy up, they've got guns-"

Daisy burst out of the bedroom and crashed into Miranda, sending her tumbling down the stairs.
