Porter glanced a few times at Katie, but she seemed to have fallen asleep. Porter reached back to check her pulse. It was weak, fading all the time. ‘Hang in there,’ Porter muttered under his breath. I didn’t go to all this trouble just to bring a corpse across the border.

His own condition wasn’t too bad. The shirt had long since been ripped off his back, and he’d taken a battering to his back when he jumped out of the car. His jeans had been torn in a couple of places, and the soles of his trainers had been burnt when they were escaping from the burning mine. There was a hole in the left shoe and the right one wasn’t in much better shape. His chest was a mess of cuts and bruises, and there wasn’t even any water in the car to start washing them.

Hassad’s right, I need to get myself cleaned up, he told himself. There’s still a long way to go before we get out of this hellhole.

‘Here,’ said Hassad.

He pulled the Polo up outside a modest one-storey house, set five hundred metres back from the main road. There was a petrol station about a mile up the road, and eight or nine hundred metres back there was a warehouse. Otherwise the place was completely isolated. A set of hills rose up behind the house, and there was flat plain in front of it, but the ground was too dusty, dry and hard for anything other than a few rough-looking bushes to grow. Safe enough, Porter decided. They could rest for a couple of hours, get themselves back in shape, and get the hell out of here.

Hassad had fished out some keys from a compartment hidden inside the spare wheel. There were at least a dozen on the ring. Hezbollah kept a string of safe houses within a short drive of the mine, he explained. They permanently expected Israeli tanks to come rolling across the border towards them, and were always prepared to evacuate in a hurry. All the keys to safe houses were kept in the cars hidden around the perimeter of the mine. Anyone could grab one at any time and make a clean getaway if the mine came under attack.

Preparation, thought Porter. They plan every move meticulously. That’s what makes them such a dangerous enemy.

He picked Katie up from the back seat of the car, cradling her in his arms. She was half asleep, but also half unconscious. Hassad had already pushed the door open. It was just after eight in the morning, and there was a slightly chill breeze in the air, but the house was warm enough. He followed Hassad through from the hallway into the main room. There wasn’t much furniture: the walls were painted plain white, and there was a sofa, and a couple of cheap wicker chairs, but at least it was clean, and it was the most luxurious place Porter had seen since he left Beirut airport. He laid Katie down on the sofa. She moaned softly as his arm caught one of her many bruises. Porter looked over to Hassad. ‘We need food and medicine,’ he said. ‘She’s in a bad way.’
