Carol made a show of searching in her bag and pulling a face in disgust. She looked around her and her eyes lit on the man at the corner table. She hitched herself off the stool, leaving her bag on the bar, and walked across to him. Now her body was between the man and the camera and they couldn’t see what was happening. She bent down, then eventually stood up, the lit cigarette between her fingers. ‘A long time to light a fag,’ Morgan said, suspicion in his voice. ‘She’s not following the script.’

‘Good for her,’ Thorson said softly as Carol returned to her bar stool. She sipped her drink and toyed with the cigarette, stubbing it out before it had burned halfway down. Then she was on her feet in a blur of movement, grabbing her bag and heading for the toilets. As she opened the door, her contact jumped to his feet, leaving his magazine, and followed her.

‘Oh shit,’ Morgan said. ‘Is there an exit out there?’

Surtees shrugged. ‘I’ve no idea. It was Mary who checked the place out.’

Thorson coloured. ‘There’s a fire exit. It’s alarmed.

As she spoke, the peal of a security siren screamed. At the same moment, all hell broke loose in their ears.

Carol ran down the narrow service alley between the tall buildings. She didn’t have to look over her shoulder to check her contact was behind her; she could hear his heavy footfalls closing on her with every step. They emerged on a narrow side street, the pavements busy with people returning to their offices after lunch. Carol slowed to a brisk walk, her contact falling into step beside her. ‘Fucking hell,’ he said. ‘You trying to kill me?’

‘I spotted a geezer from the Drugs Squad sitting outside the café in a car,’ she said, still firmly in character. ‘Him and his storm troopers turned over a mate of mine’s place a couple of months back. They didn’t get anything then, and I’m fucked if I was going to let them get anything now.’ A nearby police siren swirled through the air. ‘We’ve got to get off the street.’

‘My motor’s over in Greek Street,’ he said.

‘They might have clocked that an’ all, Carol said impatiently. She jinked across the road between the traffic-jammed cars, heading for a dingy corner pub. She pushed open the doors. It was still busy from the lunchtime crowd and she squirmed her way to the rear of the room, checking he was still with her. They squeezed into the angle between the bar and the back wall. Carol’s hand was in her bag. ‘Have you got the money?’
