Daisy ran across the front of the car and came to the driver's side. Her tan glove closed on the door handle.

The garage door was not yet fully open, but Craig could wait no longer. Just as Daisy opened the car door, he released the clutch and trod on the accelerator pedal.

The car leaped backwards as if fired from a catapult. Its roof struck the lower edge of the aluminum garage door with a clang. Sophie gave a yell of fear.

The car flew out of the garage like a champagne cork. Craig stamped on the brake. The snowplow had cleared the thick overnight layer of snow from in front of the garage, but more had fallen since, and the concrete apron was slippery. The Ferrari went into a backwards skid and stopped with a bump against a bank of snow.

Daisy came out of the garage. Craig could see her clearly in the gray dawn light. She hesitated.

The car phone suddenly spoke in a female voice. "You have one new message."

Craig pushed the gearshift into what he hoped was first. He eased the clutch out and, to his relief, the tires found purchase and the car moved forward. He turned the wheel, heading for the way out. If only he could make it onto the drive, he could get away from here with Sophie and summon help.

Daisy must have had the same thought, for she fumbled in the pocket of her jacket and brought out a gun.

"Get down!" Craig yelled at Sophie. "She's going to shoot!"

As Daisy leveled the gun, he stamped on the accelerator and swung the steering wheel, desperate to get away.

The car went into a skid, slipping across the icy concrete. Alongside his fear and panic, Craig had the feeling of deja vu: he had skidded this car, in this place, only yesterday, a lifetime ago. Now he struggled to control the vehicle, but the ground was even more slippery after a night of steady snow and freezing temperatures.

He turned into the skid, and for a moment the tires gripped again, but he overdid it, and the car skidded in the opposite direction and spun around in a half circle. Sophie was flung from side to side in the passenger seat. He kept waiting for the bang of a gunshot, but none came yet. The only good thing, a part of Craig's terrified mind told him, was that it was impossible for Daisy to take steady aim at a vehicle that was being driven so erratically.

The car stopped, with great good luck, in the middle of the drive, facing directly away from the house and toward the lane. The path in front of Craig had obviously been swept by the snowplow. He had a clear road to freedom.

He pressed on the accelerator pedal, but nothing happened. The engine had stalled.

Out of the corner of his eye, he saw Daisy raise the gun and take careful aim at him.

He turned the key, and the car jerked forward: he had forgotten to take it out of gear. The mistake saved his life for, in the same instant, he heard the unmistakable firecracker bang of a gun, only slightly deadened by the soft snow covering everything; then the side window of the car shattered. Sophie screamed.

Craig knocked the stick into neutral and turned the key again. The throaty roar filled his ears. He could see Daisy taking aim again as he pressed the clutch and found first gear. He ducked involuntarily as he pulled away, and it was lucky that he did, for this time his side window smashed.

The bullet also went through the windshield, making a small round hole and causing the entire pane of glass to craze over. Now he could see nothing ahead but blurred shapes of darkness and light. Nevertheless he kept the accelerator depressed, doing his best to stay on the driveway, knowing he would die if he did not get away from Daisy and her gun. Beside him, Sophie was curled up in a ball on the passenger seat, hands covering her head.

On the periphery of his vision, he saw Daisy running after the car. Another shot banged. The car phone said: "Stanley, this is Toni. Bad news-a break-in at the lab. Please call my mobile as soon as you can."

Craig guessed that the people with guns must be connected to the break-in, but he could not think about that now. He tried to steer by what he could see out of the smashed side window, but it was no good. After a few seconds, the car went off the cleared path, and he felt the sudden drag as it slowed. The shape of a tree appeared in the crazed glass of the windshield, and Craig slammed on the brakes, but he was too late, and the car hit the tree with a terrific crash.

Craig was thrown forward. His head hit the broken windshield, knocking out shards of glass, cutting the skin of his forehead. The steering wheel bruised his chest. Sophie was flung against the dashboard and fell with her bottom on the floor and her feet up on the seat, but she swore and tried to right herself, so he knew she was all right.

The engine had stalled again.

Craig looked in the rearview mirror. Daisy was ten yards behind him, walking steadily across the snow toward the car, holding the gun in her suede-gloved hand. He knew instinctively that she was coming closer just to get a clear shot. She was going to kill him and Sophie.

He had only one chance left. He had to kill her.

He started the engine again. Daisy, five yards away now and directly behind the car, raised her gun arm. Craig put the gearshift into reverse and closed his eyes.

He heard a bang just as he stamped on the throttle. The rear window shattered. The car leaped backwards, straight at Daisy. There was a heavy thump, as though someone had dropped a sack of potatoes on the boot.

Craig took his foot off the throttle, and the car rolled to a stop. Where was Daisy? He pushed broken glass out of the windshield and saw her. She had been thrown sideways by the impact and was lying on the ground with one leg at an odd angle. He stared, horrified at what he had done.

Then she moved.

"Oh, no!" he cried. "Why won't you die?"

She reached out with one arm and picked up her gun, lying on the snow nearby.

Craig put the car into first gear.

The car phone said: "To erase this message, press three."

Daisy looked into his eyes and pointed the gun at him.

He let out the clutch and stamped on the throttle.

He heard the bang of the gun over the bellow of the Ferrari engine, but the shot went wild. He kept his foot down. Daisy tried to drag herself out of the way, and Craig deliberately turned the wheel in her direction. An instant before the impact he saw her face, staring in terror, her mouth open in an inaudible scream. Then the car hit her with a thud. She disappeared beneath its curved front. The low-slung chassis scraped over something lumpy. Craig saw that he was headed straight for the tree he had hit before. He braked, but too late. Once again, the car crashed into the tree.

The car phone, which had been telling him how to save messages, stopped in mid-sentence. He tried to start the engine, but nothing happened. There was not even the click of a broken starter motor. He saw that none of the dials was working, and there were no lights on the dashboard. The electrical system had failed. It was hardly surprising, after the number of times he had crashed the car.

But that meant he could not use the phone.

And where was Daisy?

He got out of the car.

In the driveway behind him was a pile of ripped black leather, white flesh, and gleaming red blood.

She was not moving.

Sophie got out and stood beside him. "Oh, God, is that her?"

Craig felt sick. He could not speak, so he nodded.

Sophie whispered, "Do you think she's dead?"

Craig nodded again, then nausea overwhelmed him. He turned aside and vomited into the snow.
