Krasic didn’t like the sound of this one bit. He knew hackers tended to be fully paid-up members of the paranoid tendency, but that didn’t mean they were always wrong. ‘I can’t come round now. I’m four hundred kilometres from Berlin.’ Out of the corner of his eye, he could see Tadeusz looking interested.

‘Can you get yourself to an internet café?’

‘What?’

‘An internet café. A place that rents out computers with internet access.’

‘I know what an internet café is. How does that help me?’

‘I’ll set up an account and send the stuff to you. I’ll use hotmail.com. You type in www.hotmail.com then your account name. I’ll set it up with your own first name and surname. The password is the street where I live. OK? Can you remember that?’

‘It’s a lot more secure than talking on the phone. And, if I were you, I wouldn’t hang about. You need to see this, and fast.’ The caller hung up.

‘Shit,’ Krasic muttered, tossing the phone on to the dashboard. ‘Where the fuck am I going to find an internet café?’

‘What’s going on, Darko?’ Tadeusz asked. ‘Who was that?’

Krasic swore under his breath in Serbo-Croat. ‘Hansi the hacker. He’s been doing something for me that turns out to be urgent. I need to find an internet café.’

‘Well, take the next exit. Every little town and village has internet access these days. What’s it all about?’

Krasic scowled. ‘You’re not going to like this.’

‘I’m not going to like it any better if you make me wait.’

‘After she left you last night, Caroline Jackson met another man.’

Tadeusz looked shocked. ‘You were still following her?’

‘I was still having her followed. You think I’m going to take a stranger on trust? I’ve had someone on her tail since you told me about her. And this is the first time she’s done anything at all except shopping and working out.’

‘So who was this man? Where did she meet him?’ Tadeusz was trying to sound casual, but Krasic could hear the underlying tension in his voice.

‘He has an apartment in the same block where she’s staying. When she got home, she went straight to his apartment. Rado saw them in the window. She was kissing him.’

Tadeusz shook his head. ‘He must have been mistaken. You know Rado. He’s not the sharpest knife in the drawer. They’ll have been greeting each other.’

Krasic shook his head. ‘No. I saw them myself. They were kissing each other like they meant it. And it looked like it wasn’t the first time, either. She was in his apartment for the best part of an hour and a half.’

Tadeusz clenched his fists. ‘But she didn’t spend the night?’
