It was still early in the morning when he pulled out of the underground garage and into the cul-de-sac, but he drove carefully for the couple of miles to the M4 junction. Once on the motorway, he was able to join the rush-hour traffic, whipping round the M25 motorway, orbiting the outskirts of London.

Erika felt herself regain consciousness, but the darkness was absolute. Her face was pressed against something rough. One arm was pinned under her at an angle. She brought the other arm up to touch her face, but her hand hit a solid mass a few inches above her head. She shifted, feeling the pain shoot through her face. She tasted blood and swallowed painfully. There was a rumbling, swaying motion underneath her. She felt around her the curved sides of the confined space, the metal above her, the inside mechanism of the lock, and realised she was in the boot of a car. Then a foul, pungent smell hit her. It had a tang of rot, and she heaved, barely able to catch her breath when she was forced to suck the rancid smell back into her lungs in the confined space. The car sped up and took a turn, the road bumping unevenly underneath. The gravitational force pushed Erika across to the edge of the boot, and something heavy rolled against her.

It was then that she knew she was in the back of the car with a body.

Information was coming through to the incident room fast, and Moss and Peterson were realising with horror that DCI Foster could be the next victim. The Douglas-Brown house had been searched, and was empty. Erika’s car had been found parked two streets away and the number plate for David’s car had been photographed leaving the west section of London’s congestion charge zone.

‘Simon Douglas-Brown’s secretary bought David a one-way ticket on the Eurostar to Paris,’ said Crane, coming off the phone.

‘So, not Prague,’ said Moss.

‘Shit. What about DCI Foster?’ asked Peterson.

‘She’s not in the house. She’s not in her car. She must be in his,’ said Moss. ‘Crane, how fast can we scramble a helicopter?’

‘When Chief Superintendent Marsh gives the order, four minutes,’ said Crane.

‘Okay, I’m calling Marsh,’ said Moss.

The junction sign for Ebbsfleet International Train Station loomed above, and David indicated and took the exit off the M25, slowing as he hit the ramp, which curved round and changed to a single lane carriageway. The A2 was busy with cars, but they peeled off at the turning for the Bluewater Shopping Centre, its futuristic glass spires emerging from where it sat deep in an old chalk quarry. David drove on, speeding past empty industrial wasteland, grass, and the occasional tree dotting the scrubland. He slowed when he saw the lay-by up ahead, and then turned off. He came to a halt, and had to get out of the car to unhook a chain which hung across a small dirt track.

Erika had struggled to control the fear climbing her throat – the fear of being boxed in with a dead girl, and of what would happen when they reached their destination. She had forced herself to check for signs of life, and during this had discovered the body was that of a girl with long hair, whose life had long since left her. Her eyes had adjusted to the dark, and she could make out two tiny pinpricks of light next to the inside of the locking mechanism. She had run her hands over it, slowly at first, feeling its sharp greasy contours for a weakness, a way of prising it open. The car had lurched and the body had rolled against her again, and for a brief moment she’d panicked, clawing at the lock and breaking two of her fingernails below the quick. The pain had pulled her away from the brink of losing it, and she’d forced herself to think. To remain calm.

To survive.

She’d found a small hole in the carpeting underneath her, used to pull out the layer of carpet where underneath were kept the tools and spare wheel. She’d had to lie to one side, on top of the dead girl, to get the carpet up far enough to reach under, where she’d found a wrench. She had it now, in her grip. It was cold, but her hands were sweating. She felt the car come to a stop and braced herself. A door opened, and weight shifted. Moments later, the car lurched as David got back in. She heard a door close again, and then the car set off slowly, lurching from side to side, its suspension creaking. She felt the body beside her move, and the weight shifted so that it rolled onto her, the hair on its scalp pressing against the back of her head. She closed her eyes and tried to think; to focus on what she would do.

David drove slowly along the bumpy track, which opened out to a vast, disused chalk quarry. In the centre was a deep pit filled with water. He came to a stop twenty yards from the edge, and killed the engine. He got out of the car and walked to the edge. The quarry walls were smooth. Tufts of grass grew in patches, and a small tree emerged from a break in the rock. Fifty feet below, the water was still and the weak morning sunlight bounced off dim blurry patches where the water was still frozen. To the left, the Bluewater Shopping Centre sat low on the horizon, and a couple of miles in the opposite direction, a high-speed train left Ebbsfleet International, streaking past silently on its way to the Eurotunnel crossing to Paris.
