‘Again, not in the way you think of it. Molokov served with OMON, the Russian Special Purpose Police Squad, but was kicked out, ostensibly for corruption. With so many special-forces police on the take in Moscow, that takes some doing. Molokov did three years in Matrosskaya Tishina prison in Moscow for offences linked to people smuggling. Another difference from Vitrenko, who’s never been arrested, far less faced trial and imprisonment. The truth is that Molokov built his reputation as a contract killer. He’s now officially wanted for a whole range of crimes. Molokov hates Vitrenko but can’t do anything about the situation. He and Vitrenko were on a collision course and Molokov knew he’d come out worst. So Vitrenko was able to force Molokov into partnership with him, with Molokov very much the junior partner.’

‘Why hasn’t Molokov been extradited from Germany?’ asked Maria.

‘Molokov and Vitrenko are both living here under assumed names. The difference between them is that Vitrenko is better at it – living in someone else’s skin, as it were. But the German police still don’t know what identity Molokov’s using or where to find him. And that’s where we’re ahead of the game.’

‘Oh?’

‘We have a location for him. More by accident than by design. Our main interest in Molokov is that he’s the highest-ranking member of the Vitrenko organisation who we can observe. Unlike you chasing around after small fry like Kushnier, Molokov could really give us a fix on Vitrenko.’

‘It sounds like there’s no love lost between them.’

‘There isn’t, particularly on Molokov’s side. Vitrenko has the power to keep him in check, but Molokov is a deadly son of a bitch. But there is a specific stress-point in the Vitrenko–Molokov marriage. Your Federal Crime Bureau here in Germany has a source of information within the organisation. Our intelligence suggests that Vitrenko believes the leak is from Molokov’s side. I took part in a failed operation to nail Vitrenko back on Ukrainian soil. One of Molokov’s top men, a thug called Kotkin, ended up dead, as did a member of our team who was supposedly on the Vitrenko payroll.’

Olga Sarapenko cut in. ‘What we need to know is if you are with us in this. Will you help us nail Vitrenko?’

Maria sipped her water. She noticed her hand trembling as she did so. Her wrists still ached from the rope they’d been bound with.

‘What if we were to do this legally? Locate him and get the BKA to arrest him?’

‘You know that’s not an option, Maria,’ said Buslenko. ‘That would give him a chance to slip through our fingers. You for one should know how easy that is. Anyway, that is not our objective. We are here to put an end to Vitrenko. Literally.’
